Simpleview requires that a copy of the Primary Simpleview Database is available to the integration. This needs to be done in conjunction with Simpleview itself, and it is best to be included as part of an early conversation with Simpleview so that it is part of the implementation plan.
The database copy can be placed wherever is appropriate for Simpleview as long as it is available via the Internet. The data from the production copy of Simpleview needs to be pushed into the primary database copy on a regular basis in order to keep the email lists as current as possible. The frequency of updates should be decided upon between you and Simpleview.
You will also need to have access to the primary database copy via SQL Server Management Studio's console in order to create objects in SQL server.
