EXISTENCE CONDITIONS AND CLASSIFICATION OF THE INCONSISTENCIES IN THE DATABASE INTEGRATION

Abstract

The technological progress in the areas of the hardware and the software, together with the general expansion of the computers to almost all human activities, make it easier to realize th eintegration of mny already existion databases. Unfortunately the process of the databases integration can be accompanied by many various difficulties and problems. One of them is surely the possible occurrence of the inconsistencies appearing in this process of the integration. These inconsistencies can occur at various levels and they can be of different types. Inthe paper we study the existence conditions ofr these inconsistencies and we propose a classification of certain of these inconsistencies.
