Abstract:	In this paper we first survey various examples for anomalies given in the literature [1,3,8]. We discuss the formalizations and relate them to each other and the examples. We give arguments that show that decomposition of a relation scheme can help in getting rid of deletion/insertion anomalies and can fail in getting rid of update anomalies in the decomposed case.
