Transactional or Analytical

The term OL (Online) mainly refers to interactive queries.

There are some historical reasons for the origin of the term transaction . The early database users were mostly commercial transactions, such as buying and selling, paying wages and so on. But as database applications continue to expand, transaction\transaction remains as a noun.

Transactions do not necessarily have ACID characteristics. Transactional processing is mostly random read and write with low latency. On the contrary, analytical processing is mostly periodic batch processing with high latency.
