Integracja danych to zadanie jakie stawiane jest przed aplikacjami, dla których konieczne jest pc skiwanie informacji z wielu autonomicznych i heterogenicznych źródeł. Potrzeba integracji szczegó widoczna jest w dynamicznie rozwijających się instytucjach, jakimi są banki, ale także np. w duż projektach związanych z informatyzacją instytucji rządowych i wielu innych miejscach. Jakość danych jest w literaturze definiowana w różny sposób. Potrzeba pomiaru jakości dan pojawia się wraz z napływem coraz większej ich ilości. W niniejszej pracy przedstawimy podsta' we zagadnienia związane z jakością danych, w szczególności zaś skoncentrujemy się na jakości nych zintegrowanych.

The data integration is a problem rises in the areas where applications require information from multiple autonomous and heterogeneous sources. The need of integration is seen especially in dynamically growing organizations such as banks, but also in large projects done for governmental institutions. The data quality is in the literature defined in many different ways. The need on measurement of the quality rises with the increasing number of incoming data. In this chapter we have shown basic concepts of data integration and data quality emphasising the problem of the quality of integrated data.
