RDBMS stands for Relational Database Management
System. RDBMS is the basis for SQL, and for all
modern database systems like MS SQL Server, IBM
DB2, Oracle, MySQL, and Microsoft Access. The data in RDBMS is stored in database objects
called tables. A table is a collections of
related data entries and it consists of columns
and rows.Relational Data Base Management Systems
(RDBMS) are database management systems that maintain data records and indices in tables. Relationships may be created and maintained across and among the data and tables. In a relational database, relationships between data items are expressed by means of tables. Interdependencies among these tables are expressed by data values rather than by pointers. This allows a high degree of data independence. An RDBMS has the capability to recombine the data items from different files, providing powerful tools for data usage.
