What is OLAP and OLTP?

OLAP (Online Analytical Processing) and OLTP (Online Transaction Processing) are two different approaches to working with data, aimed at different tasks.

• OLTP are systems designed for processing a large number of transactions in real-time. These are databases that support insert, update, and delete operations at high speed and ensure data integrity. Example: banking systems, reservation systems.

• OLAP are systems focused on analytical data processing, usually aggregated and historical. OLAP allows for quick execution of complex queries for analysis, report generation, and decision-making. Data in OLAP is often stored in multidimensional cubes or specialized data warehouses.

In the context of Golang, OLTP databases (e.g., PostgreSQL, MySQL) can be used for operational data work, while OLAP systems are used for analytics and reporting, possibly through integration with external BI tools or specialized storage.
