Stonebraker’s view
Stonebraker (1996) has proposed a four-quadrant view of the database world, as illustrated
in Figure 28.1. In the lower-left quadrant are those applications that process simple data
and have no requirements for querying the data. These types of application, for example
standard text processing packages such as Word, WordPerfect, and Framemaker, can use
the underlying operating system to obtain the essential DBMS functionality of persistence.
