The way in which computers manage data has come a long way over the last few decades. Today's users take for granted the many benefits found in a database system. However, it wasn't that long ago that computers relied on a much less elegant and costly approach to data management called the file-based system. relational database system [19, 20] which was designed for use with. UNIX. Most of the points made for this environment have general appli- cability to other operating systems and data managers. 2. Buffer Pool Management. Many modern operating systems provide a main memory cache for the file system. Figure 1. Each parent record has one or more child records, similar to the structure of a file system. Network. A network database is similar to a hierarchical database, except records have a many-to-many rather than a one-to-many relationship. The preceding database management systems stored data in rigid, predetermined. Management Systems. 1.3 File Oriented Approach. The earliest business computer systems were used to process business records and produce information. They were generally faster and more accurate than equivalent manual systems. These systems stored groups of records in separate files, and so they were called file.

Before the arrival of DBMS, data were processed using file processing system. File processing system consists of several application programs and each application program has its own data stored in private files. In this system the same data file cannot be shared. Hence duplication of data is required if. A database management system (DBMS) is a collection of programs that manages the database structure and controls access to the data stored in the database. In a sense. The database structure itself is stored as a collection of files, and the only way to access the data in those files is through the DBMS. Database files are vital to the operation of the RDU. Therefore, take extra precautions to safeguard them against accidental removal or other manual manipulation.
