Integrity Rules in DBMS
In DBMS systems, integrity rules, which take a prime place, are designed to ensure that the quality of data is always high, with no inconsistencies or errors. The set of principles, also known as the integrity rules or constraints, helps to manage the data stored in the system in the right way and determine whether it’s suitable for certain purposes. It is not without reason that these rules are so crucial since they are key to the overall integrity of the database and its quality. Herein, we investigate the centrality of governance regulations, illustrate the different types that exist, and provide their implementation in DBMS.
