Data warehouses allow for data analysis, including data from a dozen or so years back. The collected data is arranged and archived in a central database which facilitates control over access to data, thereby ensuring the security of the stored data.
As time goes by, IT needs arise as a natural result of the company’s development, which is why Data Warehouse end-users should maintain constant contact with BI specialists to verify current business needs.
There are several ways to analyze the collected data, depending on actual business needs; however, the most common ones are:
- periodical, standard fixed-structured reporting, with enabled filtering,
- defining reports and queries by means of SQL or generating automated reports,
- static analysis of trends and predictions,
- multi-dimensional and interactive analytical processing (OLAP),
- data mining to predict business and market trends,
