DBMS is a system that allows to insert, update, delete and
retrieve data
RDBMS stores data in the form of related tables. It allows
data security
12 rules for RDBMS are:
-data should be tabular
-accessing of data must be easy
-supports for null values in fields other than primary key
-tool must be same for database structure and for data itself
-database must support at least one programming language
-data can be represented as views
-insert,update and delete operations for multiple tables/rows
-data should be physically independent
-data must be logically independent
-integrity independence of database
-user should not know distribution of database
-modifying database structure must be through a language
