IDMSDBMS

IDMSDBMS is the controlling module within the IDMS/R DBMS. All requests enter through IDMSDBMS. For each request, IDMSDBMS interprets the verb code passed and, when necessary, calls other modules such as a database procedure or IDMSDBIO. IDMSDBMS performs all page and record manipulation and builds all journal records. IDMSDBMS then uses the information in the subschema load module and the variable subschema table to navigate the database.
