Gajini you have to study concept of Relational Database Management system.
[1] Find out what is table
[2] What are attribute
[3] What is row and column
[4] what is Primary key
[5] what is Unique key
[6] what is foreign key
[7] what is normalization (1NF,2NF,3NF & 4NF)
REF Dependency... (I think its about foreign key)
