RDBMS stands for Relational Database Management System. RDBMS data is structured in database tables, records and fields. Each RDBMS table consists of records (rows) and each record consists of one or more fields (columns).
RDBMS store the data into collection of tables (database schema), which might be related by common fields. RDBMS also provide relational operators to manipulate the data stored into the database tables. Most RDBMS use SQL as database query language.
The most popular RDBMS are MS SQL Server, IBM DB2, Oracle, MySQL and Postgress.
