There is a brand new product on the market called MVsync (
https://prosolgrp.com/mvsync/). This product has many advantages over traditional products to synchronize data to SQL server. Using MVsync, you can then access your MultiValue data using relational tools using your MultiValue dictionaries to create the definitions. MVsync can also be used for bidirectional synchronization if desired. This is a real-time synchronization of the data. Maverick Systems is a reseller in the U.S. for this product as well as MVsharp, MVrest and MVpro. These tools all have the advantage of handling data in your MultiValue data that does not conform strictly to data type rules required by Microsoft SQL and other relational databases.
