5. Enhanced Performance
With the increase in the speed of data retrieval and data analysis, we are able to store a large amount of data and can also query rapidly. Data warehouses are specially made for collecting and analyzing the data rather than only creating and modifying data that the operating system does. Implementing a data warehouse and simplified data models eases report creation and it also helps in creating custom reports for specific needs. If used with advanced SQL functionalities, it helps in optimizing the database performance.
6. BI from Heterogeneous Sources
There are many subsystems of an organization which is different physically and based on different platforms. In Business Intelligence, there is a need for merging the data from heterogeneous sources. In a Data warehouse, integration of these data is done and made accessible at a single place. Accumulating all of the data of an organization into a single container decreases data duplication which makes data warehouse a single view of a story rather than multiple stories with multiple meanings.
After getting to know how a Data Warehouse benefits an organization. Let us go through a case study for a real-world problem and its solutions in a data warehouse.
An Electric Holding Company in the US
- Business Problem – Energy Trading Systems for various submarkets were not integrated which resulted in detailed and fragmented reporting features. The business needed a combined, multi-leveled trading transaction data with a full array of risk measures for Risk and Market to Market Analysis.
- Solution Provided – A web-based risk reporting portal was implemented. It was based on customer requirements including reports with a hierarchical security model. Different roles within the organization were allowed to see the different data aggregations. The system provided a single set of reports which helped in providing a different view based on the user’s job function and line of business focus. At the highest level, the corporation could see their entire energy portfolio and can evaluate the various energy trading instruments with hedging strategies.
This case study helps us in acknowledging how a data warehouse simplifies the business model of an organization and helps in gaining more business growth through more efficient insights from the organization’s data over time.
