Operational data vs Informational data

Operational Systems vs Informational Systems
Sr. No Operational Systems Informational Systems
1.
Operational systems are designed to deal with
the running values of data.
Informational Systems deals with the collection,
compilation and deriving information from data.
2.
In operational systems, optimization of data
structure is done for transactions.
In informational systems, optimization of data
structure is done for complex queries.
3.
Operational systems have response time of
sub-seconds.
While informational systems have a response time of
few seconds to minutes.
4.
Operational systems are generally suited for
small volumes of data.
Informational Systems are mainly designed for large
volumes of data and hence convenient to use.
5. Operational systems are process oriented. While informational systems are subject oriented.
6.
Operational systems supports various data
access operations such as read, update and
delete.
Informational systems only supports read operation
for data access.
