Abstract

In this paper, we have defined two concepts in the context of the relational model for databases. First, we have formalized the notion of internal domains by what we have called name independence. We then proceeded to formally define the abstraction process in a database schema. For an abstraction to be well-defined, we required that the schema be decomposable into independent projections. We have then derived conditions for well-defined abstractions, using the concepts of multi-valued dependency and name independence.
