Smaller and Smaller Systems

Smaller and Smaller Systems

In the beginning, DBMS's were large, expensive software systems running on large computers. The size was compulsory, because to store a gigabyte of data required a large computer system. Today, many gigabytes fit on a single disk, and it is possible to run a DBMS on a personal computer. Thus, database systems based on the relational model have become available for even very small machines, and they are beginning to appear as a common tool for computer applications, much as spreadsheets and word processors did before them.
