What is RDBMS?
RDBMS stands for Relational Database Management Systems. It is a program that allows us to create, delete, and update a relational database. A Relational Database is a database system that stores and retrieves data in a tabular format organized in the form of rows and columns. It is a smaller subset of DBMS which was designed by E.F Codd in the 1970s. The major DBMSs like SQL, My-SQL, and ORACLE are all based on the principles of relational DBMS.
Relational DBMS owes its foundation to the fact that the values of each table are related to others. It has the capability to handle larger magnitudes of data and simulate queries easily.
Relational Database Management Systems maintains data integrity by simulating the following features:
- Entity Integrity: No two records of the database table can be completely duplicate.
- Referential Integrity: Only the rows of those tables can be deleted which are not used by other tables. Otherwise, it may lead to data inconsistency.
- User-defined Integrity: Rules defined by the users based on confidentiality and access.
- Domain integrity: The columns of the database tables are enclosed within some structured limits, based on default values, type of data or ranges.
RDBMS Full Form
A database is an organized collection of data stored in a computer system and usually controlled by a database management system (DBMS). The data in common databases is modeled in tables, making querying and processing efficient.
