MultiValue was a data model with a query language before it became an operating system. After running as the O/S on many common hardware platforms, it has been a run-time container on common operating systems. It is now a set of tools for running applications in .NET and the Common Language Runtime (CLR). We have entered the era of MultiValue as a toolset that dovetails with Microsoft development platforms, both .NET and SQL Server. MV has matured from the PICK O/S to an MV DBMS to MV# Tools.
SQL Server is optional. MV# works with MultiValue DBMS products too.
