  What is a Data Definition Language?       Data Definition Language (or DDL)  includes those SQL statements that create and drop locations, databases and database objects such as tables and indexes, it   also includes statements to alter database objects and impose integrity constraints on tables. Interactive Data Manipulation Language       What is interactive Data Manipulation Language?

Embedded SQL statements are SQL statements written inline with the program source code, of the host language.

Last blog we talked about what exactly a DBMS  (Database Management System)  is, but now let's dig in a little deeper about it, what it's functions and pros and cons are. What are the functions of DBMS? Down below is a list of it's functions.
