2.5 Components of DBMS Suite
The DBMS is actually a complex conglomeration of software components working
together for a set of common objectives. For the purpose of illustration, we may represent
the essential components of the DBMS as the following:
•
DBMS Engine
•
Data Definition Subsystem
•
User Interface Subsystem
•
Application Development Subsystem
•
Data Administration Subsystem
•
Data Dictionary Subsystem
•
Data Communications Manager
•
Utilities Subsystem
These functional components (illustrated in Figure
2-3
) are not necessarily tangibly
identifiable, but they exist to ensure the acceptable performance of the DBMS.
