OLTP: It stands for Online Transaction Processing, and it refers to a group of software tools that are useful for supporting transactional systems. One of the most essential characteristics of an OLTP system is its ability to maintain consistency. To avoid single points of failure, the OLTP system frequently employs decentralized planning. This system is primarily intended for a large number of end-users to conduct quick transactions. Furthermore, searches in such databases are often basic, require quick response times, and return only a few entries in contrast. As a result, the number of transactions per second serves as a useful metric for those systems.
OLAP: OLAP is for Online Analytical Processing, and it refers to a group of software systems that have a lower frequency of online transactions than others. The efficiency of computing in OLAP systems is heavily dependent on reaction time. As a result, such systems are commonly employed in multi-dimensional schemas for data mining or preserving aggregated historical data.
