static database management system
static DBMS

    (static DBMS) A database consisting of
   "information-based relationships", one that is rigorously
   structured to facilitate retrieval and update in terms of
   inherent relationships.  This creates a static environment
   wherein the locations of the related records are already
   known.  Typical static DBMS are either hierarchical (IMS,
   System 2000) or a CODACYL (network or plex) DBMS (such as
   TOTAL, IDMS, IDS, DMS-2).  These environments
   facilitate rapid, high volume processing of data.

   The opposite is a dynamic database management system.
