Q: What is the main advantage of using indexing in a data warehouse?
Solution: Indexing improves query performance by allowing the database to find data more quickly, which is crucial in a data warehouse environment.
Steps: 6
Step 1: Understand what a data warehouse is. A data warehouse is a system used for reporting and data analysis, where large amounts of data are stored.
Step 2: Know what indexing means. Indexing is a technique used in databases to make searching for data faster.
Step 3: Realize that in a data warehouse, users often run complex queries to analyze data.
Step 4: Understand that without indexing, the database would have to look through all the data to find what is needed, which takes a long time.
Step 5: Learn that indexing creates a special structure that helps the database find the data much faster.
Step 6: Conclude that the main advantage of using indexing in a data warehouse is improved query performance, allowing users to get results quickly.
