What is the difference between OLTP and OLAP databases?
a) OLTP is for transactional processing, OLAP is for analytical processing
b) OLTP stores historical data, OLAP stores real-time data
c) OLTP databases are non-relational, OLAP databases are relational
d) OLTP databases are used for backups, OLAP databases are used for disaster recovery
Answer:
a) OLTP is for transactional processing, OLAP is for analytical processing
Explanation:
OLTP (Online Transaction Processing) systems are designed for managing day-to-day transactional data, such as order processing, customer management, and inventory tracking. They focus on fast, efficient processing of individual transactions and ensure ACID compliance.
OLAP (Online Analytical Processing) systems are designed for data analysis and reporting. They handle complex queries and aggregations on large datasets, often pulling data from multiple OLTP systems to provide insights and support decision-making.
OLTP systems prioritize transaction speed and data integrity, while OLAP systems prioritize query performance and data aggregation for analysis.
