A data warehouse is a specially designed database in which Business Intelligence class system data is stored. It is a tool for aggregating distributed data sources in one centralised location to facilitate the preparation of business analyses and reports.

The main feature of a data warehouse is the multidimensionality of its structure, within which partial data – both internal and external – concerning the organisation are collected, stored, structured and finally analysed. Thanks to this multidimensionality, it is possible to perform complex analyses quickly and flexibly, regardless of the source of data.

The quality, transparency and accuracy of data on which the organisation’s operations are based can be ensured by implementing a specially designed data warehouse. First of all, it is used to read current and historical data, with sizes counted in gigabytes and terabytes.

The data warehouse turns out to be indispensable, especially in the case of those organisations which cannot cope with the amount of collected data or when these data change dynamically, making analysis and reporting difficult. Creating a data warehouse is a complex process, which should be adjusted to the initial situation of a given organisation.

Designing, implementing and maintaining a data warehouse is a real challenge, which is worth entrusting to specialists. At EBIS we have both technical knowledge in the field of database building as well as many years of business experience gained during the implementation of business analysis projects for clients from various industries. All activities are preceded by an in-depth analysis of the client’s requirements and the organisation’s specificity.
