>> 1.Stored procedure and Function
Compare to the similar concepts in e.g. Pascal. A procedure doesn't have to have a return value, and function must.

>> 2.String and StringBuffer.
A String is immutable, i.e. you can't change the value of the String inside. Whenever you do e.g. substring on a String, a new String object is created and returned to you.
A StringBuffer is mutable, so when building strings up from parts, you would want to use a StringBuffer.
StringBuffer is synchronized.

>> 3.why we use Triggers?Why can,t we check the condition in the client side itself instead of using triggers?
It is better (more efficient) to respond to events rather than poll for value changes. A trigger will send an event when a certain condition is met.
