SQL Server stores all login information on security catalog system tables. By querying the system tables, SQL statements can be re-generated to recover logins, including password, default schema/database, server/database role assignments, and object level permissions. A comprehensive permission report can also be produced by combining information from the system metadata.

One of my client’s requirements is to migrate and consolidate his company departments’ databases to SQL Server 2008. As I know the environment, they are using MySQL , MS-Access and SQL Server with different applications. Now the company has decided to have a single dedicated SQL Server 2008 database server to host all the applications. So there are a few things to do to upgrade and migrate from MySQL and MS-Access to SQL Server 2008. For the migration task, I found the SQL Server Migration Assistant 2008 (SSMA 2008) is very useful which reduces the effort and risk of migration. So in this tip, I will do an overview of SSMA 2008.
