What a Data Warehouse is Not

Recently, I was at a conference, and I heard the following discussion about what a data warehouse was. One person suggested that a data warehouse was really all the old legacy systems connected by software that could access the data. By calling such a contraption a data warehouse, the organization could avoid having to do the hard and complex work of integration.

Using T-SQL CROSS APPLY and OUTER APPLY

That said, even though my personal focus is pretty much OO, I still miss stuff. SQL Server 2005 came out with the CROSS APPLY and OUTER APPLY operators and I have just started learning how to use APPLY in the last month or so.

SQL Server Unique Constraints for Large Text Columns

We are storing large text and URLs that are over 900 bytes in some of our tables and have a requirement to enforce uniqueness in those columns. But SQL Server has a limitation that index size can't be over 900 bytes. How do I enforce uniqueness in these columns and is it possible to achieve this in SQL Server 2005 and above? What are my different options to solve this problem? I heard that we can use CHECKSUM to create a hash, but is it possible to avoid collisions in the hash value as we are storing millions of rows?
