In the lower-right quadrant are those applications that process complex data but again
have no significant requirements for querying the data. For these types of application, for
example computer-aided design packages, an OODBMS may be an appropriate choice of
DBMS. In the top-left quadrant are those applications that process simple data and also
have requirements for complex querying. Many traditional business applications fall into
this quadrant and an RDBMS may be the most appropriate DBMS. Finally, in the top-right
quadrant are those applications that process complex data and have complex querying
requirements. This represents many of the advanced database applications that we examined
in Section 25.1 and for these applications an ORDBMS may be the most appropriate
choice of DBMS.
