Early in the era of database management technology, analyst George Schussel answers questions about the direction of the database field and application development technology. The questions posed were:

  2. Some vendors recommend one DBMS/4GL for operational systems and another different DBMSI4GL for information centre/DSS applications, while other vendors say that a single system is the best approach. Your opinion?

  4. Are the differences between inverted list DBMSs such as System 1032, Model 204 and ADABAS and truly relational DBMS such as Oracle, INGRES, and DB2 important?
  5. Within the next five years, will artificial intelligence find its way into 4th generation languages?
