Check If Auto Update Statistics Is Enabled With DATABASEPROPERTY

How do you check if auto update statistics is enabled on your database? It is pretty easy to check that, you can use the DATABASEPROPERTY function
Run the following line of code

SELECT DATABASEPROPERTY('pubs','IsAutoUpdateStatistics') AS IsAutoUpdateStatistics

If 1 is returned(true) it is enabled, if 0 is returned(false) then it is not enabled

Now to save me (and you) time I have pasted a code block below with all the properties, just change the database name from pubs to your database name and run the code


DECLARE @v VARCHAR(55)
SELECT @v = 'pubs'

SELECT
DATABASEPROPERTY(@v,'IsAnsiNullDefault') AS IsAnsiNullDefault,
DATABASEPROPERTY(@v,'IsAnsiNullsEnabled') AS IsAnsiNullsEnabled,
DATABASEPROPERTY(@v,'IsAnsiWarningsEnabled') AS IsAnsiWarningsEnabled,
DATABASEPROPERTY(@v,'IsAutoClose') AS IsAutoClose,
DATABASEPROPERTY(@v,'IsAutoCreateStatistics') AS IsAutoCreateStatistics,
DATABASEPROPERTY(@v,'IsAutoShrink') AS IsAutoShrink,
DATABASEPROPERTY(@v,'IsAutoUpdateStatistics') AS IsAutoUpdateStatistics,
DATABASEPROPERTY(@v,'IsBulkCopy') AS IsBulkCopy,
DATABASEPROPERTY(@v,'IsDboOnly') AS IsDboOnly,
DATABASEPROPERTY(@v,'IsDetached') AS IsDetached,
DATABASEPROPERTY(@v,'IsEmergencyMode') AS IsEmergencyMode,

Microsoft Unveils Vision and Road Map to Simplify SOA, Bridge Software Plus Services, and Take Composite Applications Mainstream

Attendees gathered at the fifth annual Microsoft SOA & Business Process Conference today, where the company shared its vision and road map to simplify the effort required to design, build, deploy and manage composite applications within and across organizations. Microsoft Corp. announced “Oslo,” the code name for the set of technical investments that help customers realize this vision.

This multiyear, multiproduct effort utilizes the company’s top engineering talent to build on the model-driven and service-enabled principles of Microsoft Dynamic IT (http://www.microsoft.com/presspass/press/2007/jun07/06-04TechED07PR.mspx ) and extend the benefits of service-oriented architecture (SOA) beyond the firewall. The “Oslo” technology innovations further Microsoft software-plus-services efforts by providing extensions to the application platform to help developers bridge between on-premise and off-premise projects. As part of a technical road map, Microsoft made available new tools and guidance to help organizations take advantage of “real-world SOA” today, including new SOA resources from Microsoft and a host of industry partners.

“Many customers are challenged to realize the promise of SOA given today’s complexities,” said Jeff Raikes, president of Microsoft Business Division. “The combination of our current software-plus-services approach and the new wave of ‘Oslo’ technologies will enable IT to deliver high-impact business solutions.”

Today, applications cannot easily span the boundaries between technologies, between business and IT, and between an organization, its suppliers and its customers. Microsoft’s continued investments in SOA and business-process management (BPM) technologies will help customers better connect across these boundaries using a service-oriented and model-driven approach. As part of “Oslo,” Microsoft will work to deliver a unified platform integrating services and modeling, moving from a world where models describe the application to a world where models are the application.

“It’s time to help developers and IT professionals extend the capabilities of SOA to address the new ‘blended’ world of software plus services and cross-boundary collaboration,” said Robert Wahbe, corporate vice president of the Connected Systems Division at Microsoft. “‘Oslo’ will enable a new class of applications that are connected and streamlined — from design through deployment — reducing complexity, aligning the enterprise and Internet, and simplifying interoperability and management.”

At the conference today, Microsoft also demonstrated an upcoming community technology preview of Microsoft BizTalk Services (http://labs.biztalk.net/default.aspx), featuring additional support for interoperability, Web 2.0 services, identity standards and workflow in the cloud.

Building on the technology available today, the “Oslo” advancements will be delivered through Microsoft server and tools products in five key areas:

Server. Microsoft BizTalk Server “6” will continue to provide a core foundation for distributed and highly scalable SOA and BPM solutions, and deliver the capability to develop, manage and deploy composite applications.

Services. BizTalk Services “1” will offer a commercially supported release of Web-based services enabling hosted composite applications that cross organizational boundaries. This release will include advanced messaging, identity and workflow capabilities.

Framework. The Microsoft .NET Framework “4” release will further enable model-driven development with Windows Communication Foundation (WCF) and Windows Workflow Foundation (WF).

Tools. New technology planned for Visual Studio “10” will make significant strides in end-to-end application life-cycle management through new tools for model-driven design of distributed applications.

Repository. There will also be investments in aligning the metadata repositories across the Server and Tools product sets. Microsoft System Center “5,” Visual Studio “10” and BizTalk Server “6” will utilize a repository technology for managing, versioning and deploying models.


Customers are realizing the benefits of Microsoft’s real-world approach to SOA and vision by employing today’s technology, including BizTalk Server and BizTalk Services, along with the upcoming .NET Framework and Visual Studio. On Feb. 27, 2008, Microsoft will continue the wave of innovation by also launching Windows Server 2008, .NET Framework 3.5, and Microsoft SQL Server 2008.

Reinforcing their commitment to SOA, Microsoft, Accenture and Avanade recently announced the Accenture and Avanade Solutions Showcase, located on Microsoft’s corporate campus. This Solutions Showcase highlights the power of SOA while offering customers customized solutions in areas such as the next-generation workplace, infrastructure optimization and business intelligence. The first solution to be developed in conjunction with the new Solutions Showcase, a human resources (HR) solution that helps organizations quickly and efficiently bring on board new employees, was demonstrated during Robert Wahbe’s keynote address at the Microsoft SOA & BPM Conference.

“The Solutions Showcase illustrates the benefits of bringing together the technology skills and industry expertise of Accenture, Avanade and Microsoft in a single location,” said Paul


Daugherty, chief architect for Accenture. “Our customers are always looking to extract more value from their application development investments and can benefit from this joint innovation as they develop mission critical-solutions on the Microsoft platform.”

Customers and partners can visit the new Microsoft SOA and Business Process Solution Center at http://www.microsoft.com/soa for additional information and resources, including patterns and practices based on the most successful customer implementations.

Rhino Mocks 3.3 Released

Rhino Mocks 3.3 has been released.

Bug Fixes:
Fixing inconsistency in how Is.Equals handled ICollection instances, now it will compare them by their values, not their Equals()
Fixing NASTY bug where setup result that were defined in a using(mocks.Ordered()) block were not registered properly.

Improvements:
Changing error message to "are you calling a virtual (C#) / Overridable (VB) method?" - make it friendlier to VB guys.
Exception for Record will not trigger a ReplayAll(), which can mask the exception.
Adding a check for running on Mono to avoid calling Marshal.GetExceptionCode in that case.

New features:
Adding support for calling void methods using Expect.Call
Adding remoting proxies.
Made IMethodOptions generic. Allows compile time type safety on Return.
Adding a PublicFieldConstraint

Oracle Database 11g Generally Available on Microsoft Windows Platform

Oracle today announced the general availability of Oracle(r) Database 11g on the Microsoft Windows platform. Oracle Database 11g on Windows helps organizations of all sizes tackle the demands of rapid data growth, changing environments, and the need to deliver higher quality of services while reducing and controlling IT costs.
"Oracle is committed to providing choice, and we continue to deliver on that promise with the release of Oracle Database 11g on Windows," said Andy Mendelsohn, senior vice president of Database Server Technologies, Oracle. "Optimized for Windows, Oracle Database 11g helps growing businesses address their increasing data management demands with unrivaled price/performance and scalability."

Optimized for Windows and .NET
Oracle Database 11g is optimized for Windows platforms and services. Administrators can take advantage of new Windows-specific features including database backup and recovery using Windows Volume Shadow Copy Service as well as enhancements in Active Directory and Kerberos integration. New features in Oracle Database 11g and enhanced integration with Windows offer a fast, reliable and secure foundation for mission-critical applications. Oracle's recent world record for price/performance with the TPC-C benchmark running Oracle Database 11g on Windows(1) demonstrates Oracle Database's ability to cost-effectively meet the needs of businesses of all sizes without compromising performance.

As a Premier partner in the Microsoft Visual Studio Industry Partner (VSIP) program, Oracle offers tight integration between Oracle Database and Microsoft Visual Studio. With the release of Oracle Database 11g on Windows, .NET developers will experience even faster performance and improved developer productivity. The new Oracle client result cache can significantly improve performance of repetitive queries. Oracle SecureFiles provides breakthrough performance for storage and retrieval of unstructured data such as documents, XML, images, and video. New indexing and storage methods for XML provide up to 15 times improved performance.

In previous releases, Oracle has delivered new and unique features for Windows customers such as Oracle Real Application Clusters, which turns a cluster of low-cost, industry-standard servers running Windows into a highly available, scalable and secure platform for running database and packaged applications. Oracle Database 11g is no exception and offers new capabilities, including:

* Oracle Real Application Testing enables businesses to efficiently test the changes made to their IT environment from operating systems to servers to software, reducing the risks and costs associated with such changes;

* Oracle Advanced Compression capabilities delivers compression ratios of 2x to 3x or more for all data types for added cost-effective storage of data;

* Oracle Total Recall offers an easy, practical way to query the historical changes to data for change tracking, auditing and compliance;

* Oracle Active Data Guard enhances the performance of production systems and provides a more cost-effective disaster recovery solution by enabling the offloading of resource intensive tasks such as queries and backups to a single physical standby database; and,

* Oracle Partitioning automates many manual data partitioning operations and extends existing range, hash and list partitioning to include interval, reference and virtual column partitioning.

Melbourne Health Tests Oracle Database 11g on Windows
Melbourne Health is a major public health provider in Victoria, Australia that provides comprehensive acute, sub-acute and community-based health care programs. Melbourne Health is the lead driver behind the Bio21:Molecular Medicine Informatics Model (MMIM), a platform that provides clinical researchers access to data from disparate existing databases across multiple disease types at multiple institutions, co-located in a virtual repository.

A participant in the Oracle Database 11g beta program, Melbourne Health tested DICOM image storage, metadata (image information) extraction and DICOM image retrieval, ability to anonymize the image, generation of thumbnails, and conformance validation of Oracle Database 11g on Windows and Linux platforms.

"Oracle Database 11g on Windows has provided a number of new features such as increased capabilities for management of unstructured data including medical imaging, improved data compression for managing rapidly growing volumes of data, and data encryption for securing sensitive data that we would consider implementing in support of the Bio21:MMIM project. Authorized researchers will be able to access de-identified information about an image via the MMIM SAS interface, just as they do for other clinical research data," said Dr. Marienne Hibbert, Ph.D., MMIM Project Director.

Webcast Explores IT Trends and Challenges in Windows Environment
A Webcast featuring IDC Research Vice President Carl Olofson and hosted by Oracle and Redmond Magazine, is scheduled on Wednesday, October 24, 2007 at 12:00 PM ET / 9:00 AM PT.

Video: Pascal Bourque - Building a rich datagrid in WPF

Channel 9 has posted their latest video: Pascal Bourque - Building a rich datagrid in WPF

From the site:

We talk about what its like to develop a rich control using WPF, mainly focusing on the custom theming of the grid. It really shows off the whole concept of seperating the UI interaction and style from the core code. And with that capability, diving into redefining a grid's purpose and how real-time visualization changes can be used effectively.

I'm hoping they take my suggestion of a custom themes contest and run with it. It'd be interesting to see what other type of skins people could create.

Sort Values Ascending But NULLS Last

This is a frequent request in newsgroups and fora. People want to sort the column in ascending order but don't want the NULLS at the beginning.
Oracle has this syntax: ORDER BY ColumnName NULLS LAST;
SQL Server does not have this. But there are 2 ways to do this. The first one is by using case and the second one by using COALESCE and the maximum value for the data type in the order by clause.

The 2 approaches with a datetime data type



DECLARE @Temp table(Col datetime)
INSERT INTO @Temp VALUES(getdate())
INSERT INTO @Temp VALUES('2007-10-19 09:54:03.730')
INSERT INTO @Temp VALUES('2006-10-19 09:54:03.730')
INSERT INTO @Temp VALUES('2005-10-19 09:54:03.730')
INSERT INTO @Temp VALUES('2006-10-19 09:54:03.730')
INSERT INTO @Temp VALUES('2004-10-19 09:54:03.730')
INSERT INTO @Temp VALUES(NULL)
INSERT INTO @Temp VALUES(NULL)




SELECT *
FROM @Temp
ORDER BY COALESCE(Col,'9999-12-31 23:59:59.997')




SELECT *
FROM @Temp
ORDER BY CASE WHEN Col Is NULL Then 1 Else 0 End, Col





The 2 approaches with an integer data type



DECLARE @Temp table(Col int)
INSERT INTO @Temp VALUES(1)
INSERT INTO @Temp VALUES(555)
INSERT INTO @Temp VALUES(444)
INSERT INTO @Temp VALUES(333)
INSERT INTO @Temp VALUES(5656565)
INSERT INTO @Temp VALUES(3)
INSERT INTO @Temp VALUES(NULL)
INSERT INTO @Temp VALUES(NULL)




SELECT *
FROM @Temp
ORDER BY COALESCE(Col,'2147483647')




SELECT *
FROM @Temp
ORDER BY CASE WHEN Col Is NULL Then 1 Else 0 End, Col

Interview With Kalen Delaney About Inside Microsoft SQL Server 2005 Query Tuning and Optimization

Inside Microsoft SQL Server 2005: Query Tuning and Optimization I am a big fan of Inside Microsoft SQL Server 2005 The Storage Engine so when I saw that yet another book got published in this series I just had to check it out. Inside Microsoft SQL Server 2005: Query Tuning and Optimization is very well written gets to the point and give you the answers that you need. I decided to contact Kalen to see if she would be willing to do an interview, by now you know that the answer is yes of course ;-)


The question-and-answer session with Kalen that follows was conducted via email.

What is the audience for this book, is it the enterprise user or can a small department benefit from the tips in this book?
Because this book deals with query tuning, anyone who writes SQL queries for SQL Server can benefit. Very little in the book is geared towards system tuning, so the size of the machine doesn’t really matter. Now of course, if you have a very small system with very small tables, you won’t get as much benefit out of tuning your queries. However, if you have any tables of more than a few thousand rows, and you do any joins, you will need to tune your queries. In addition, the issues of blocking and concurrency control can impact any system, no matter how small.

What new technologies in SQL Server 2005 do you think are the most beneficial for performance?
For very large databases, the best new technology is partitioning. For any size system, if you have had serious performance problems due to blocking, you might find a big performance benefit by using one of the snapshot-based isolation levels, but you really need to understand the resource costs that come along with the improved performance. For your individual queries, I think the new optimizer hints and query level recompiles can make a big difference. For indexes, the ability to add included columns to nonclustered indexes can give some of your hard-to-tune queries a major performance boost.

What will a person who reads this book gain in terms of understanding how to performance tune a server?
The focus of this book is not so much on tuning the server, but on tuning queries. There is more in Inside SQL Server 2005: The Storage Engine on server issues such as memory and processor management. The biggest server wide issues are covered in Chapter 5, when I talk about managing the plan cache, and how and when query plans are reused.

Is the book geared towards a beginner/intermediate level user or do you have to be an advanced user to really utilize the information in this book?
The book is not geared towards beginners, but everyone should be able to get something out of it. It’s primarily geared to SQL Server developers and DBA’s who have been working with SQL Server for a while, and have encountered performance problems that they are trying to find solutions for.

With all the changes in SQL Server 2005, how critical has the tempdb become in regards to performance?
Tempdb has always been important. In SQL Server 2005, if you are using one of the snapshot-based isolation levels, you are going to have to be more aware of the demands placed on tempdb, both in the sizing requirements and the additional I/O resources needed. Fortunately, SQL Server 2005 provides tools to monitor tempdb, including a dozen new performance monitor counters, and a dynamic management view, sys.dm_db_file_space_usage, that keeps track of how much space in tempdb is being used for each of the different kind of object stored in tempdb.

I understand that this is the first time you wrote with a team of other writers; can you tell us something about that experience?
I initially thought that not having to write the whole volume by myself meant that I could get it done sooner, but that was not the case. Everyone had their own schedule and their own way of writing. The personal aspect of working with the other authors was great. I deeply respect all of the others and it was an honor to be working so closely with them. I had some concerns about the depth of coverage and I wondered whether all the chapters would end up being as deep as I hoped for, but that turned out not to be a major problem. The only real issues were agreeing on a common terminology and coding style, and even that wasn’t that big of an issue, because I got to do a final editing pass on everyone’s chapters.

What SQL Server books are on your bookshelf?
All of the Inside SQL Server books are there, of course, and all of Ken Henderson’s books. Bob Beauchemin’s book is in my car, to read while I am waiting for the ferryboat, and while on the ferry. I also have technical books that aren’t SQL Server specific, such as Jim Gray’s Transaction Processing, Russinovich’s and Solomon’s Windows Internals, Chris Date’s Introduction to Database Systems and Mike Stonebraker’s Readings in Database Systems.

Why do you write technical books?
I love working with SQL Server and trying to find out all I can about it. When I found that I could explain difficult concepts in a training environment, I thought I could do the same thing in a written format, and reach more people that way. I have always loved explaining things, ever since I was a teaching assistant for High School Math.

Will you be updating your books for SQL Server 2008?
I have just started meeting with my editors at Microsoft Press about SQL Server 2008, and it looks like a revision is in the plans. We’re really looking at it as just a revision, with the same structures as the current books, with straightforward changes and the inclusion of new features.

Name three things that are new in SQL Server 2005 that you find are the most valuable?
Dynamic Management Views, Dynamic Management Views, and Dynamic Management Views!
Oh, you wanted three different things? ;-) How about XML query plans and optimization hints. (I’m also very fond of many of the new TSQL constructs, but I was only talking about things that I cover in my new book.)

Name three things which are coming in SQL Server 2008 that you are most excited about?
You’ll have to ask me this next time. I have actually been avoiding SQL Server 2008 while I was getting my Query Tuning and Optimization book finished, because I didn’t want to get distracted.

Can you list any third party tools that you find useful to have as a SQL Server developer/admin?
I’ve tried a few other products, but usefully I find that it is much easier to just stick with the Microsoft line and use the tools provided with the product.

Name some of your favorite non-technical books.
Oh, I love to read. It would be impossible to list my favorite books, but I can tell you my favorite authors, most of whom write science fiction: Lois McMaster Bujold, Ursula LeGuin, Sheri Tepper, Orson Scott Card, Octavia Butler, Elizabeth Moon. I also love to read historical fiction like Leon Uris.

    What am I doing wrong?

    THIS APPEARED ON CRAIG'S LIST

    What am I doing wrong?

    Okay, I'm tired of beating around the bush. I'm a beautiful (spectacularly beautiful) 25 year old girl. I'm articulate and classy.
    I'm not from New York. I'm looking to get married to a guy who makes at least half a million a year. I know how that sounds, but keep in mind that a million a year is middle class in New York City, so I don't think I'm overreaching at all.

    Are there any guys who make 500K or more on this board? Any wives? Could you send me some tips? I dated a business man who makes average around 200 - 250. But that's where I seem to hit a roadblock. 250,000 won't get me to central park west. I know a woman in my yoga class who was married to an investment banker and lives in Tribeca, and she's not as pretty as I am, nor is she a great genius. So what is she doing right? How do I get to her level?

    Here are my questions specifically:

    - Where do you single rich men hang out? Give me specifics- bars, restaurants, gyms

    -What are you looking for in a mate? Be honest guys, you won't hurt my feelings

    -Is there an age range I should be targeting (I'm 25)?

    - Why are some of the women living lavish lifestyles on the upper east side so plain? I've seen really 'plain jane' boring types who have nothing to offer married to incredibly wealthy guys. I've seen drop dead gorgeous girls in singles bars in the east village. What's the story there?

    - Jobs I should look out for? Everyone knows - lawyer, investment banker, doctor. How much do those guys really make? And where do they hang out? Where do the hedge fund guys hang out?

    - How you decide marriage vs. just a girlfriend? I am looking for MARRIAGE ONLY

    Please hold your insults - I'm putting myself out there in an honest way. Most beautiful women are superficial; at least I'm being up front about it. I wouldn't be searching for these kind of guys if I wasn't able to match them - in looks, culture, sophistication, and keeping a nice home and hearth.

    it's NOT ok to contact this poster with services or other commercial interests

    PostingID: 432279810


    THE ANSWER
    Dear Pers-431649184:

    I read your posting with great interest and have thought meaningfully about your dilemma. I offer the following analysis of your predicament.
    Firstly, I'm not wasting your time, I qualify as a guy who fits your bill; that is I make more than $500K per year. That said here's how I see it.

    Your offer, from the prospective of a guy like me, is plain and simple a crappy business deal. Here's why. Cutting through all the B.S., what you suggest is a simple trade: you bring your looks to the party and I bring my money. Fine, simple. But here's the rub, your looks will fade and my money will likely continue into perpetuity...in fact, it is very likely that my income increases but it is an absolute certainty that you won't be getting any more beautiful!

    So, in economic terms you are a depreciating asset and I am an earning asset. Not only are you a depreciating asset, your depreciation accelerates! Let me explain, you're 25 now and will likely stay pretty hot for the next 5 years, but less so each year. Then the fade begins in earnest. By 35 stick a fork in you!

    So in Wall Street terms, we would call you a trading position, not a buy and hold...hence the rub...marriage. It doesn't make good business sense to "buy you" (which is what you're asking) so I'd rather lease. In case you think I'm being cruel, I would say the following. If my money were to go away, so would you, so when your beauty fades I need an out. It's as simple as that. So a deal that makes sense is dating, not marriage.

    Separately, I was taught early in my career about efficient markets. So, I wonder why a girl as "articulate, classy and spectacularly beautiful"
    as you has been unable to find your sugar daddy. I find it hard to believe that if you are as gorgeous as you say you are that the $500K hasn't found you, if not only for a tryout.

    By the way, you could always find a way to make your own money and then we wouldn't need to have this difficult conversation.

    With all that said, I must say you're going about it the right way.
    Classic "pump and dump."
    I hope this is helpful, and if you want to enter into some sort of lease, let me know.

    Halo 3 Records More Than $300 Million in First-Week Sales Worldwide

    Interactive entertainment will never be the same, with the launch of one title that has changed the way the world thinks about video games. “Halo® 3” has captured the attention of consumers worldwide and has made history as one of the biggest entertainment launches of all time.

    Microsoft Corp. today announced that “Halo 3” has officially become a global phenomenon, garnering more than $300 million in sales in the first week alone. The critically acclaimed Xbox 360® exclusive, which was released worldwide on Tuesday, Sept. 25, is the fastest-selling video game ever and already one of the most successful entertainment properties in history.

    Initial reports from retailers worldwide show console sales have more than doubled compared with the weekly average before the launch of “Halo 3.” With games such as “Halo 3,” “Madden 08” (EA Sports), “Mass Effect” (Microsoft Game Studios) and “Rock Band” (Harmonix), Xbox 360 has the greatest lineup in the history of video games and is the only console where consumers can play all the year’s biggest blockbusters.

    “‘Halo’ is truly a cultural phenomenon, and the launch of ‘Halo 3’ is an important milestone for Xbox 360 and for video games as entertainment and as an art form,” said Bill Gates, chairman of Microsoft. “‘Halo 3’ embodies our vision for the future of entertainment, where some of the world’s greatest creative minds will deliver a new generation of interactive storytelling.”

    “Halo 3” is quickly staking its place as the most popular Xbox LIVE® game in history with members gathering in record numbers to play on the world’s largest online gaming and entertainment network on TV. More than 2.7 million gamers have played “Halo 3” on Xbox LIVE in the first week, representing nearly one-third of the 7 million Xbox LIVE members worldwide. Within the first day of its launch, “Halo 3” players worldwide racked up more than 3.6 million hours of online gameplay, which increased more than elevenfold to 40 million hours by the end of the first week, representing more than 4,500 years of continuous gameplay. Since “Halo 3 launched,” gamers have unlocked nearly 30 million achievements. In its first week alone, “Halo 3” drove a record number of Xbox LIVE Gold Memberships as hundreds of thousands of new members gathered online with friends, family members and other gamers around the world to collectively compete and complete the game.

    “Halo 3” is the conclusion to the epic trilogy and picks up where “Halo 2” left off, answering questions about the fates of the beloved protagonist Master Chief™ and his artificial intelligence sidekick Cortana as they struggle to save humankind from destruction at the hands of the alien coalition known as the Covenant. In addition to the rich storyline, “Halo 3” continues the franchise’s grand tradition of delivering innovative online multiplayer experiences via Xbox LIVE. The game’s online multiplayer and innovative four-player cooperative gameplay for Xbox LIVE Gold users, the much-talked-about Saved Films feature that enables players to capture and save their favorite moments on their hard drives, and Forge, an innovative map editor that enables myriad customization options, are just some of the new features gamers are experiencing.

    Developed by Bungie Studios and published by Microsoft Game Studios, the “Halo” franchise is exclusive to the Xbox 360 video game and entertainment system and optimized for the Xbox LIVE online entertainment network. “Halo 3” was released in 37 countries and 17 languages. To date, more than 20 million copies of the games in the “Halo” trilogy have been sold worldwide.

    Record week-one sales come on the heels of the previously announced $170 million in sales in the U.S. within the first 24 hours of the game’s release, which marked not just the biggest video game launch, but the biggest entertainment launch in history. The Xbox 360 title beat previous U.S. sales records set by blockbuster openings for entertainment events such as the release of “Spider-Man 3” and “Harry Potter and the Deathly Hallows.” In addition, more than 1.7 million copies of “Halo 3” were pre-ordered in the United States, making it the fastest pre-selling game in history, surpassing the previous record-setting pre-sales of “Halo 2.”
