Implementation of Data Quality Requirements in Information Systems

At the moment variety of methods and commercial tools are available that can be used to model business systems and implement data integrity constraints through the functionality of active database management systems. Unfortunately, these tools do not support data validation – the implementation of business rules as integrity constraints, triggers stored procedures is used only to avoid entry of erroneous data into the database. Regardless the use of data quality checks at the entry of data into the database, errors in data exist. The application of business rules approach in data quality assurance is widely discussed in the publications of recent years. Currently only domain specific data management tools support data validation, but these tools do not support system modelling at all or are suitable to model only some aspects of system. Therefore, there are no tools that support both system modelling and data validation.
