SQL Server 2008 R2 Integration Services offer a wide range of pre-built components, which deliver generic functionality commonly required when performing extraction, transformation, and loading tasks.

A benefit of using computed columns is that they can save developers from having to write calculation logic at the application layer; at the table level, the application can simply reference the computed column. In addition, performance can be improved by persisting a computed column and building an index on it.
