Why is it important for the tables in a database to be related by common fields?

The essence of a database is that it contains the data in the simplest possible way. Therefore all fields uniquely related to one field (known as the Key field) should be placed in a separate file. Now when processing another file containing that key field you have access to all the dependent fields. For example a personnel file might include a persons Job Description as a code. When reading that file the computer can use the code to access all the particulars of that job without having to store a copy for every person with that job.

Tables in a database need to be related by common fields to establish connections between different pieces of data. This relationship enables efficient querying, data retrieval, and ensures data integrity by maintaining consistency and avoiding redundant information. It allows for complex data retrieval operations across multiple tables in a database.

What is RBDMS?
RDBMS stands for Relational Database Management System. RDBMS data is structured in database tables, fields and records. Each RDBMS table consists of database table rows.

RDBMS also provide relational operators to manipulate the data stored into the database tables. Most RDBMS use SQL as database query language.
