Synonyms and SQL Server Express
I've been a big fan of using SQL Server aliases for a long time because it allows you to make physical location of SQL Servers transparent to the client machines. With SQL Server 2005 Microsoft introduced synonyms, allowing you to define logical names for objects in another database or even on another server. This could be among other things beneficial if you need to move some tables to another database. Instead of recoding your application, you can define synonyms and point them to the new location (I wrote an article for SearchSQLServer.com about synonyms recently, you can get more details there if interested) This week I realized that synonyms can have another great benefit. As you know, SQL Server Express has a limit of 4GB per database. If your database begins to grow close to 4GB, you can move one or more large tables to another database on the same server, create synonyms in the original database and point them to the new location. I tested it on my SQL Server Express instance and it does work as expected. So with this knowledge, this limitation might become less of an obstacle for you to consider SQL Server Express.
