Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: OLAP systems are optimized for complex queries and analysis. Reason R: OLTP systems are designed for transactions processing with large read-only queries. In the light of the above statements, choose the most appropriate answer from the options given below
Evaluating OLAP and OLTP System Statements
The question asks to evaluate two statements about OLAP (Online Analytical Processing) and OLTP (Online Transaction Processing) systems.
Assertion A Analysis
Assertion A states: "OLAP systems are optimized for complex queries and analysis."
- This statement is correct. OLAP systems are designed for multidimensional data analysis, enabling users to query and analyze large amounts of data from multiple perspectives, often involving complex aggregations and calculations.
Reason R Analysis
Reason R states: "OLTP systems are designed for transactions processing with large read-only queries."
- This statement is incorrect. OLTP systems are optimized for processing a high volume of short, transactional operations (like inserting, updating, or deleting records) that are typically characterized by read/write operations. They are not designed for or optimized for handling large, complex, read-only analytical queries.
Conclusion
Since Assertion A is correct and Reason R is incorrect, the most appropriate choice is the one that reflects this.
Therefore, A is correct but R is not correct.
This corresponds to Option 3.
