What are the key differences between a fact table and a transactional table in a relational database?
- Fact tables are used for online transaction processing (OLTP), while transactional tables are used for online analytical processing (OLAP)
- Fact tables contain aggregated data, while transactional tables store detailed, raw data
- Fact tables have a primary key, while transactional tables have foreign keys
- Fact tables store current data, while transactional tables store historical data
Fact tables in a relational database store aggregated data, often derived from transactional tables. Transactional tables, on the other hand, store detailed, raw data. Recognizing these differences is essential for efficient database design and querying in both OLAP and OLTP environments.
