Study Notes
Introduction to Databases: Problems with File-Based Approach
- File-based systems are collections of application programs that perform services for end users.
- Each program in a file-based system defines and manages its own data.
- One of the limitations of a file-based approach is the separation and isolation of data.
- Each program in a file-based system maintains its own set of data.
- Users of one program may be unaware of potentially useful data held by other programs.
- Another limitation of a file-based approach is the duplication of data.
- Same data is held by different programs in a file-based system.
- This leads to wasted space and potential data inconsistencies.
- Database concepts are introduced as an alternative to file-based systems.
- A Database Management System (DBMS) is a software system that provides an interface between users and the database.
- The major components of the DBMS environment include the database, DBMS software, hardware, and users.
- There are advantages and disadvantages to using a DBMS instead of a file-based system.
