Components of the DBMS environment

Components of the DBMS environment

• We can identify five major components in the DBMS environment:
• Hardware
• The computer system(s) that the DBMS and the application programs
• run on. This can range from a single PC, to a single mainframe, to a
• network of computers.
• (2) Software
• The DBMS software and the application programs, together with the operating system, including network software if the DBMS is being used over a network.
• (3) Data
• The data acts as a bridge between the hardware and software components and the human components. As we’ve already said, the database contains both the operational data and the meta-data (the ‘data about data’).
