BDD systems show a number of advantages mainly related to the system performance increase by reducing costs relative to processing and transmission of data and, last but not least, to the fact that BDD system better fits in the organizational structure of an economic unit. The disadvantages are related to the high complexity of design applications). If your DBMS does not provide facilities for handling distributed conflicts, they will have to be dealt with through applications,. This is more difficult for such a system which, besides the complexity of a computer network, has problems related to the data distributed processing, as well as ensuring a high level of transparency of the distribution. The process of achieving a BDD system is complex and generally justified in one of the following situations: when conducting large database, which provides support for most activities in an organization, where frequent extension of the existing system or interconnecting a set of existing database are expected.
