bhai, maine last 2,3 yrs solve kiye hai, DBMS mujhe aata hai, and networking mujhe nahi aata hai. bas cut off clear karna hai, and wrong attempt nahi karna hai, thats the strategy for me. DBMS, networking mein tough questions aayenge as usual.

Entity integrity defines a row as a unique entity for a particular table. Entity integrity enforces the integrity of the identifier columns or the primary key of a table, through UNIQUE indexes, UNIQUE constraints or PRIMARY KEY constraints.
Referential integrity preserves the defined relationships between tables when rows are entered or deleted. In SQL Server, referential integrity is based on relationships between foreign keys and primary keys or between foreign keys and unique keys, through FOREIGN KEY and CHECK constraints. Referential integrity makes sure that key values are consistent across tables. This kind of consistency requires that there are no references to nonexistent values and that if a key value changes, all references to it change consistently throughout the database.
When you enforce referential integrity, SQL Server prevents users from doing the following:
Adding or changing rows to a related table if there is no associated row in the primary table.
