Table 1-1 provides some examples. Companies that compete in the marketplace need databases to store and manage their mission critical and other essential data. 4 CHAPTER 1 ■ INTRODUCTION TO DATABASE SYSTEMS Table 1-1. Illustrations of the Importance of Databases Software Category Database Need Operating Systems A sophisticated internal database is needed to keep track of various resources of the computer system including external memory locations, internal memory locations, free space management, system files, user files, etc.
Fortunately, there is no shortage of excellent resources on this topic (for instance, see [Comer 2015]). 4 The Database Management System The database management system (DBMS) is the software that facilitates creation and management of the database. When a user issues a request via some DSL (typically SQL), it is the DBMS that interprets such a request, executes the appropriate instructions, and responds to the request. Depending on the nature of the initial request, the response may be relayed (by the DBMS) directly to the end user, or indirectly to the end user via an executing application program.
