# What are the Advantage and disadvantage of Session?

**Advantages:**\
Session provide us the way of maintain user state/data.\
It is very easy to implement.\
One big advantage of session is that we can store any kind of object in it. :eg, datatabe, dataset.. etc\
By using session we don't need to worry about data collesp, because it store every client data separately.\
Session is secure and transparent from the user.\
**Disadvantages:**\
Performance overhead in case of large volumes of data/user, because session data is stored in server memory.\
Overhead involved in serializing and de-serializing session data, because in the case of StateServer and SQLServer session modes, we need to serialize the objects before storing them.\
