Unify Programming Models Windows API .NET Framework Consistent API availability regardless of language and programming model ASP Stateless, Code embedded in HTML pages MFC/ATL Subclassing, Power, Expressiveness VB Forms RAD, Composition, Delegation

Make It Simple To Use ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

SQL Server Integration Design Goal ,[object Object],[object Object],[object Object],[object Object]

SQL CLR Functionality VS .NET Project CLR hosted by SQL (in-proc) Define Location.Distance() Assembly: geom.dll VB, C#, … Build SQL Server SQL Data Definition: create assembly … create function … create procedure … create trigger … create type … SQL Queries: SELECT name FROM Supplier WHERE Location.Distance ( @point ) < 3
