QUESTION POSED ON: 14 October 2005
Hi Brian. I read your article on MS SQL Server vs. Oracle. Are there any differences between these two DBMSs with respect to their maintenance of data integrity?

>
For the most part, SQL Server and Oracle handle data integrity about the same, at least on the surface. Both systems handle primary key constraints, foreign keys, check constraints and triggers for complex data integrity business rules. Under the covers, they handle these differently, but those differences are negligable to the end user and the application.
