oltp-vs-olap

Online Transaction Processing(OLTP) is a transactional processing system that involves processing transactional data and updating a back-end database to reflect the new input. Relational databases(RDMS) are a suitable choice for OLTP since it requires a database that can handle numerous queries and updates while supporting quick response times.

Online Analytical Processing(OLAP) is an analytical processing system that can handle any analytical process. OLAP tools are used to perform complex queries and bring insights from large data sets especially those collected from multiple databases.

Let’s discuss the difference between OLTP and OLAP.
