One thing I have noticed in forums is that people are curious about features available with different flavors of SQL Server.
Most of the times questions comes like I installed SQL Server 2008 Express and find Database Mail missing,Do I need to re-install SQL Server again?
The answer is SQL Server Express doesn’t support Database Mail.
Its not really easy to remember what feature comes in with which edition,however there is a very smart and easy comparison page provided my Microsoft.
You have the option to select multiple versions and compare the features here.Hope this post will help you answer some of the feature related questions.
Thanks for reading.
