Advantages of Data Warehousing
A data warehouse is a central repository of information that can be analyzed.
This analysis of data can help to make more informed decisions.
Data and analytics have become indispensable to businesses to stay competitive. Business users rely on reports, dashboards, and analytics tools to extract insights from their data, monitor business performance, and support decision making.
Data warehouses power these reports, dashboards, and analytics tools by storing data efficiently to minimize the input and output (I/O) of data and deliver query results quickly to hundreds and thousands of users concurrently.
Benefits of a data warehouse:
- -Informed decision making
- -Consolidated data from many sources
- -Historical data analysis
- -Data quality, consistency, and accuracy
- -Separation of analytics processing from transactional databases, which improves performance of both systems
