Filtering the Spectrum of Internet Threats
Because of the proliferation of Web-based threats, you can no longer rely on basic firewalls as your sole network protection. Attackers continue to devise clever methods for reaching victims, such as sending crafty Web links through Instant Messaging (IM) clients or email, or by simply linking to other Web sites that your employees might surf. This free white paper examines the threats of allowing unwanted or offensive content into your network and describes the technologies and methodologies to combat these types of threats.
Playing a Role in SQL Server's BI Future
by Brian Moran
It sounds a bit weird to be talking about "future generations" of SQL Server when SQL Server 2005 is so new and many of you are still using SQL Server 2000. However, Microsoft developers are already hard at work designing and planning the next version of SQL Server, code-named Katmai, and the business intelligence (BI) team is already looking for end users to provide feedback and insight for SQL Server 2005 that will help shape future versions of SQL Server.
Microsoft recently sent out a survey to some people in the BI community asking for feedback. When I received the survey, I contacted Microsoft and asked if it would be interested in hearing from SQL Server Magazine UPDATE readers. Of course, Microsoft was thrilled with the idea.
The Microsoft SQL Server Design and Usability team is actively seeking BI users to participate in several user-research activities centered on the BI capabilities of SQL Server. The activities are designed to help the team better understand the responsibilities, pain points, and needs of BI users and shape the direction of future releases of SQL Server. Microsoft is looking for feedback from a broad subset of BI users who are interested in the following topics:Data Warehouse Design
It would be much too easy for me to comment on the fact that the Microsoft SQL Server team is collecting feedback in a non-structured, data-entry format with no domain checking of data fields to ensure data integrity; so I won’t. Instead, I encourage you to copy the survey form below into an email message, include "SQL Server BI Survey" as the Subject of the email, and send your responses to Lisa Mueller, who is managing this process at Microsoft, at firstname.lastname@example.org

Locate Invalid SSIS Characters to Prevent Errors
You can use the SQL Server Import and Export Wizard to export a table. However, if the SQL Server 2005 Integration Services (SSIS) package has a table that ends with an invalid SSIS character, you might see an error that indicates something similar to "Could not instantiate the source component." For a list of invalid SSIS characters and more information about the error, read the Microsoft article "You may receive an error message when you try to export a table by using the SQL Server Import and Export Wizard."

March Reader Challenge Solution: Enforcing Restricted Uniqueness on Columns
by Umachandar Jayachandran, email@example.com
Congratulations to Chris Hedgate and Marcos Kirchner. Chris Hedgate won first prize of $100 for the best solution to the March Reader Challenge, "Enforcing Restricted Uniqueness on Columns." Marcos won second prize of $50. You can read a recap of the problem and the solution to the March Reader Challenge.
April Reader Challenge: Querying Tables and Views on a Linked Server Now, test your SQL Server savvy in the April Reader Challenge, "Querying Tables and Views on a Linked Server" (below). Submit your solution in an email message to firstname.lastname@example.org by March 16. Umachandar Jayachandran, a SQL Server Magazine technical editor, will evaluate the responses. We'll announce the winner in an upcoming SQL Server Magazine UPDATE. The first-place winner will receive $100, and the second-place winner will receive $50.
Here's the challenge:
Michael is a database consultant who’s working on a project at a client’s site. He needs to create a SQL Server 2000 data warehouse that integrates data from the company’s other databases. Michael plans to use the linked server feature to write some of the scripts that will migrate the data and perform distributed queries.
One data source that he must integrate is an IBM DB2 database. He used the IBM OLE DB Provider for DB2 to create a linked server called DB2_SRVR1 for the database. There are certain tables and views that he wants to query from the DB2 server on an ad hoc basis or use in his scripts, but when he tries to query one such table using the following four-part name
SELECT * FROM DB2_SRVR1.DB_CAT.SALES.SALES_SUMMARY
he gets the error
The OLE DB provider "IBMDADB2" for linked server "DB2_SRVR1" does not contain the table ""DB_CAT"."SALES"."SALES_SUMMARY"". The table either does not exist or the current user does not have permissions on that table.
Help Michael do the following:
1. Find the list of tables or views as exposed by the data source that he can easily query from SQL Server on a linked server
2. Quickly determine the correct way to specify the four-part name for the DB2 table (i.e., the catalog and schema part of the four-part name)
4. Events and ResourcesDevConnections provides world-class education for developers, architects, DBAs, and IT professionals.

In a Nutshell: SQL Server 2005 Memory Maximums
How much memory SQL Server 2005 can support seems like a simple question. In this week's blog "SQL Server 2005 Memory Maximums," Kevin Kline explains that there is no simple answer to this question, but there are many items you can look at in your environment to help you determine the memory maximum for your enterprise. For example, Kevin lists some of the predetermined upper-limit memory maximums for SQL Server 2005, OSs, and hardware. He also supplies links to some helpful Microsoft resources about memory maximums. Read the tips that Kevin provides in his blog this week and let him know if you found this information helpful.
