In the DDT, you can create a Deployment Data package for the messaging tables and when you deploy your database structure to SQL Server using the DDT, it will deploy the messages as well. Or you create a program to read the Messages and MessageLanguages tables and script the items to deploy along with your data if you script the database.If you want to use the DDT, right-click on the Deployment Data node in the treeview of your profile, and select the "Deployment Data Wizard" option. Just follow it and select Messaging and it will create the DD records for you.
