What is the difference between DB2 OLTP and DB2 Data Warehouse?

DB2 OLTP (Online Transaction Processing) and DB2 Data Warehouse are two different database management systems provided by IBM for different types of data processing needs:

• DB2 OLTP: OLTP databases are optimized for handling a large number of transactions in real-time. It is designed for operational usage where transactions are short and simple, such as online shopping, banking transactions, etc. DB2 OLTP databases are normalized to minimize redundancy and are typically used for day-to-day transactional processing.
• DB2 Data Warehouse: Data Warehouse databases are used for analytical processing and reporting. They are optimized for handling complex queries over large volumes of historical data. DB2 Data Warehouse databases are denormalized to improve query performance and support data analysis and decision-making processes.

In summary, while DB2 OLTP is designed for transactional processing in real-time, DB2 Data Warehouse is designed for analytical processing and reporting over historical data.
