Stored Procedures Advantages

I found this in the book "The Guru's Guide to SQL Server Stored Procedures, XML, and HTML" by Ken Henderson and thought it might be helpful to the class:

Stored Procedure Advantages
Although you can do most of the things a stored procedure can do with simple ad hoc Transact-SQL code, stored procedures have a number of advantages over ad hoc queries, including

• Execution plan retention and reuse
• Query autoparameterization
• Encapsulation of business rules and policies
• Application modularization
• Sharing of application logic between applications
• Access to database objects that is both secure and uniform
• Consistent, safe data modification
• Network bandwith conservation
• Support for automatic execution at system start-up
