Sync DB is a powerful tool that allows you to transfer data from your doForms database into a relational database, such as Microsoft SQL Server. Once set up, Sync DB automatically migrates each form collected into the new database.
Sync DB tracks all changes to linked form, and can handle changes to the structure of the form. Any changes to a linked form will be reflected in the relational database's tables; these changes are also documented with a robust audit trail that lets you see exactly what has changed, and when.
