If you're dying to dabble with business intelligence (BI), but don't know where to start, you might want to investigate SQL Server Accelerator for Business Intelligence. On June 25, 2003, Microsoft announced the product's latest release, which includes several improvements on the older version:
- Support for SQL Server 2000 Standard and Enterprise editions
- Support for Office 2003
- The ability to generate a solution from an XML file, which lets developers more easily integrate SQL Server Accelerator for BI directly into their products
- Separation of the application-generation and deployment processes so that developers can deploy applications faster
- Support for drillthrough actions in count measures, which enhances the reporting capabilities of generated applications
The support for SQL Server 2000 Standard Edition is particularly nice because it opens up SQL Server Accelerator for BI to a much wider audience than the previous version, which required SQL Server Enterprise Edition. SQL Server Accelerator for BI employs industry best practices and automates the creation of the back end for a customized BI solution. These features let SQL Server customers spend less time coding and more time building unique end-user BI applications.
Developing a complex BI and data-warehousing solution isn't easy, and SQL Server Accelerator for BI isn't going to cure all your BI problems. However, the product does provide infrastructure, back-end processing, and rich analytics that you can customize without too much effort. SQL Server Accelerator for BI is most valuable if your analytical needs closely match the core data models and analytics included in the product. You'll find out-of-the-box solutions built around retail sales and marketing, and the SQL Server Accelerator for BI Web site also includes links to download to free models for manufacturing and financial services environments.
Don't expect SQL Server Accelerator for BI to be as simple to use as typical Microsoft wizards. The product's new version is best suited to individuals who are already experienced in using Microsoft tools to build BI solutions. But the product isn't off limits for novices; less experienced users can learn from the frameworks. And you can even learn quite a bit simply by reading the detailed "Prescriptive Architecture Guides for BI" that come with the product and reviewing the data model design and analytic measures that are included in each of the four solutions.
As with other Microsoft products, SQL Server Accelerator for BI is "platform play;" Microsoft encourages companies to build on top of these products solutions that other SQL Server customers can use. SQL Server Accelerator for BI is designed so that you can tie into the generation tools through metadata and create your own templates for rolling out data marts. This functionality might make sense for a corporate IT department that needs to provide a starting point for internal development efforts or for a third-party software company that has rich, analytic industry knowledge and wants to package that content into a reuseable tool.
You can download SQL Server Accelerator for BI for free at http://www.microsoft.com/solutions/bi/ssabi/nextsteps/default.asp. Notice that the download site forces you to sign in with a Microsoft Passport account. Personally, I use my passport account regularly, but I don't like the fact that Microsoft is making people get passport accounts just for the download. Don't let this requirement stop you from evaluating this handy suite of tools, though, if BI is on your horizon.

2. SQL SERVER NEWS AND VIEWS
Microsoft adopted a standardized naming schema for all SQL Server hotfix patches or updates that the company creates or distributes. The new schema uses the format "ProductName-KBArticleNumber-BuildNumber-Language.exe." For example, a SQL Server 2000 hotfix name appears as "SQL2000-KB123456-8.00.0000-ENU.exe," and a SQL Server 7.0 hotfix name is "SQL70-KB123456-v7.00.0000-ENU.exe."
For more information about the new naming schema, see the Microsoft article "INF: New Naming Schema for Microsoft SQL Server Hotfix Packages" at http://support.microsoft.com/default.aspx?scid=kb;en-us;822499 .
The voting has closed in SQL Server Magazine's Instant Poll for the question, "What kind of authentication do you use in your SQL Server environment?" Here are the results (+/- 1 percent) from the 499 votes:
- 65% SQL Server and Windows authentication (mixed)
- 12% Windows authentication
- 23% Both, for different situations
- 0% I'm not sure
The next Instant Poll question is "Do you use SQL Server Accelerator for BI?" Go to the SQL Server Magazine Web site and vote for 1) Yes, 2) No, but I'm interested in the new release, 3) No, and I'm not interested.

Microsoft provides several tools for working with binary large object (BLOB) data—native text, ntext, or image data types in SQL Server. In "BLOB Access Technologies," Michael Otey describes seven of the most important access technologies for working with BLOBs in SQL Server. Read this July SQL Server Magazine article at
Sailor is copying data from eight tables in an Oracle database to SQL Server by using the Microsoft ODBC Driver for Oracle and the DTS Wizard. Although some of the data appears to copy successfully, for four of the eight tables, Sailor gets the error message "Provide generated code execution exception: EXCEPTION_ACCESS_VIOLATION." Sailor has run queries against the tables in FOCUS and Microsoft Access 2002 without getting this error; what's causing it? See what other DBAs have said, and offer your advice, on SQL Server Magazine's Security forum at the following URL:

Most DBAs know that growing a file dynamically is an expensive operation that degrades performance because write and read activity to the file must temporarily be blocked while the file is growing. However, when managing space for the tempdb database, many DBAs forget the performance impact of auto-growing files. SQL Server rebuilds tempdb each time the database system is stopped and restarted. Tempdb files might have auto-grown, which is the default configuration, since SQL Server was last started. SQL Server doesn't remember the size of the tempdb files when it rebuilds tempdb during a restart. Instead, SQL Server resets the files to the size they were manually configured to be.
Consider the following situation. Tempdb in SQL Server 2000 defaults to having one data file that has the logical name tempdev. The initial size of this file is 8MB. Assume that you manually increase the file size to 500MB by using the ALTER DATABASE command. The file subsequently grows to 550MB through auto-grow operations. SQL Server will reset the tempdev file to 500MB when it rebuilds tempdb. Now, assume that no one manually increased the file size from 8MB to 500MB. Instead, SQL Server auto-grew tempdb to 550MB. In this case, SQL Server resets tempdev back to 8MB when it's stopped and restarted.
The operations that grow a database file can diminish performance because reads and writes are blocked each time the file is grown. In addition, auto-growing the file might contribute to fragmentation on the physical disks. Also, the default growth increment for tempdb is 10 percent. So, for example, SQL Server would need to invoke many auto-grow operations to grow tempdev from 8MB to 550MB. That's bad. However, it's worse if the same cycle happens whenever SQL Server is restarted, assuming that 550MB is the average high-water mark that tempdb reaches during typical operations. Even worse, you might have a hard time troubleshooting why performance is sometimes slower immediately after a server is rebooted.
You can use the query below to find tempdb files that have auto-grown since SQL Server was last stopped and started.
SELECT alt.filename ,alt.name ,alt.size * 8.0 / 1024.0 AS originalsize_MB ,files.size * 8.0 / 1024.0 AS currentsize_MB FROM master.dbo.sysaltfiles alt INNER JOIN tempdb.dbo.sysfiles files ON alt.fileid = files.fileid WHERE dbid = db_id('tempdb') AND alt.size <> files.size
In general, manually setting tempdb files to a reasonable size will help you avoid significant auto-growth operations. Most importantly, if tempdb files do auto-grow, you need to determine whether the new file sizes are reasonable high-water marks. If they are, consider manually setting the file size to compensate. For example, if a file auto-grew from 8MB to 550MB, you could manually set the file size to 551MB. The file would then be rebuilt to a size of 551MB when SQL Server was stopped and restarted the next time.
