with operational data, which is data involved in the operation of a particular system and it is characterized by a large number of short on-line transactions (INSERT, UPDATE, and DELETE).

The main emphasis for OLTP systems is put on very fast query processing, maintaining data integrity in multi-access environments and an effectiveness measured by number of transactions per second.

Example: In a banking System, you withdraw amount through an ATM. Then account Number, ATM PIN Number, Amount you are withdrawing and Balance amount in account are operational data elements.

OLAP An OLAP (On-line Analytical Processing)

deal with Historical Data or Archival Data, and it is characterized by relatively low volume of transactions. In addition, the Queries needed for these systems are often very complex and involve aggregations as for OLAP systems the response time is an effectiveness measure.
