Data warehouses

Data collection

 

Data warehouses are an essential element of a company IT system. Organized data provide basis for all sorts of analyses and reports – that is provision of access to all the information used in the company.

 

Comarch Business Intelligence enables collection and safe storage of information in data warehouses, generation of various analyses, as well as simple and user-friendly acquisition and transformation of data from various sources.

 

Usually, data are loaded from numerous source systems, data warehouses or even individual flat files during the lowest workload of sources, using ETL process.

Data quality

 

Part of the data loading process is Data Quality process, which ensures its quality. Many times, the human factor causes incorrect analyses, which entail wrong decisions. Analyses could include duplicate items, language errors, or simply missing data, etc. 

 

Such inconsistencies and errors in the data are eliminated in the Data Quality process, via complete validation of the analysed data – which gives us greater certainty of data correctness.

 

Usually, this involves sets of formal and business principles which describe the given processes occurring in a company.

Area of analyses

 

This term is related to analytical areas and multivariate analyses. A common solution in this respect is OLAP, that is an analytical cube. 

 

This allows data to be efficiently processed, as well as stored in business-comprehensible models, based on facts, measurements and dimensions.
