The Relativity Data Manager is used in the single-tier (or non-client/server) configuration of Relativity where the complete Relativity DBMS resides on a single Windows machine. This component implements the ODBC interface, the file to relational database transformations, and the application data file access routines. All the data files to be accessed must be accessible from the Windows machine, either because the files exist on disk drives attached to that machine or are accessible using the Windows network file system.
