Creating a data warehouse
The foundation of all BI activities is structured data. Analysing them allows transforming the collected information into practical knowledge, which will be used to draw conclusions and forecast phenomena. However, the success of these processes depends on the use of a data warehouse, also called a database or analytical database.
A data warehouse – what is it?
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.
Building a data warehouse
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 organisations 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.
The key benefits of implementing a data warehouse in an organisation are:
- easy access to information
- making the right decisions faster
- increased control over data
- enhanced data protection
- automation of reporting processes
- establishment of a permanent data source
