The following illustration depicts a schematic representation of the DWH reference architecture.īefore files can be uploaded to the DWH, it is often the case that the heterogeneous information is translated into a uniform presentation form.

The individual components of a data warehouse do not necessarily have to come from one provider as the respective services can also be rendered by different software products or individual solutions. In addition, there is also a central control component a data warehouse manager that assigns specific administrative functions to every level of the DWH. Of course, the system architecture of a DWH changes depending on the specific product and provider - fundamentally they orientate themselves around a technical structure based on a modular model, made up of three levels: The phases of data warehousing are reflected in the typical structure, the so-called reference architecture of data warehouse systems. The process of managing and evaluating a DWH is known as data warehousing and involves the following phases: A DWH functions as a database for dating mining methods and is the basis of all considerations in the area of performance management and the strategic company direction. It’s usually the case that users are just granted reading access. As a central point for all relevant company files, the DWH serves the purpose of company-internal knowledge management. Dispositive data: If operating data is brought together (aggregated) in a central location, saved for the long term, and prepared for analysis, it can then be referred to as a dispositive data.Ī DWH offers analysts a comprehensive view of heterogeneous data files and makes it possible to gather operational figures in the context of online analytical processing (OLAP).Some of these typical data sources include operating data handling systems like product management systems, enterprise resource planning (ERP), information or ordering systems, and, of course, accounting programs.
Operative data: Operating data refers to transaction orientated information that arises in companies from day to day and is generated from administrative and accounting systems.Thus, operative data becomes dispositive data: Many companies carry over historical data periodically from data handling systems into such a data warehouse to prepare them for access at a later date as well as strategic analysis in the context of business intelligence (BI).
This concludes this brief summary of data warehouse basics.According to its definition, a data warehouse (DWH) is a data bank system separate from an operative data handling system, in which data from different, sometimes even very heterogeneous sources, is compressed and archived for the long term. With the internal data structure of a warehouse usually taking two forms.
