OLTP::
It Is Exclusively designed for Transaction purpose only,when we use this for analytical process it will have load on data base.
We can Maintain only transactional data i.e current data.
Integration across different modules is tough task.
OLAP:: It is used for analytical processing.
In This we can maintain the historical data.
Integration across different modules is easy.
