Developing a Data Quality Algebra,..Clearly, the validity of the computed quality is a function of the validity of the quality figures of the underlying base relations. The latter figures obtained via sampling and other techniques are themselves prone to error. In the absence of more stringent information for each base relation, the

Developing a Data Quality Algebra,ugh a database query. Since the quality of the derived data is a function of the query, the emphasis is on estimating the quality for the output of every operator that could be present in the relational algebra. By postulating the impact on the quality for each operator in theoretical terms, the qua
