A SQL Server-based site database for Smart Interop Publisher provides a way for you to organize projects containing Smart Models. The first time you start the product, you are prompted to either create a new site database or upgrade site databases that you have defined in previous versions of Smart Interop Publisher.
You must have at least one site database to contain your projects. Afterwards, you can use the Configure Site Database Command to create other site databases for various projects. Smart Interop Publisher supports both local and remote SQL server sites. See How do I organize my files?.
