Synergy DBMS is the file management system for Synergy/DE, enabling you to store and manage your data. Its primary file format is ISAM, which uses a data file index for fast access. Synergy DBMS also supports Synergy relative files, Synergy sequential files, and Synergy stream files. On OpenVMS, Synergy DBMS is implemented with RMS (Record Management Services).
