#Object_Oriented_Model
How DBMS works?
Any Software program stores Data in a Database with the help of DBMS.
Any Software application can store, retrieve, manage, and administrate via #SQL.
SQL (Structured Query Language) is a query language that is used to perform various types of operations on a Database via DBMS Software.
The queries fired by SQL are divided into four groups.
1.DDL (Data Definition Language)
Create, Alter, Drop, Rename
2. DML (Data Modification Language)
Insert, Select, Update
3. DCL (Data Control Langaue)
Grant
Revoke
4. DTCL (Data Transaction Control Language)
