What is Dependency in a DBMS?
The dependency concept in DBMS is the logical representation of the relationship with attributes (columns) within a table or data resource. It goes into analyzing the causality between one variable and another. This is how one attribute determines or affects the other. Dependencies, in turn, play an important role in ensuring database integrity remains constant, consistency remains among the data while allowing easy identification of redundancies within the database schema.
Fully Functional Dependency in DBMS
In the case of database management systems (DBMS), knowledge of dependencies is vital for the base built on this and it is a must for the development of the database that is most useful and practical. Special interdependency, which is expressed in the schema of the database, is based on the rule of changing attributes by changing the rest of the schema’s attributes. One of the more powerful normalization forms, fully functional dependency, remains an important key to the normalization process and ensuring reliability and integrity of data. We’ll look into the enabler of totally working with dependency and the way it is connected with the design of a database.
