🔵 What is OLAP?
OLAP (Online Analytical Processing) software performs multidimensional analysis on massive amounts of data from a data warehouse, data mart, or other unified, centralised data storage at rapid speeds. OLAP collects data from several relational data sets and reorganises it into a multidimensional structure for quick processing and in-depth analysis.
🔵 What is OLTP?
A software programme or operating system that supports transaction-oriented applications in a three-tier design is known as OLTP. It enables and supports the execution of many real-time database transactions. OLTP analyses daily transactions and is often performed in a multi-access internet-based setting. It performs query processing while also ensuring and protecting data integrity.
