Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  describe our experience with CQA/CDB, a prototype rational linear constraint database. First,  show that the standard semantics of constraint databases lead to an anomaly when queried in the presence of missing attributes. In CQA/CDB, this anomaly is avoided by enriching the CDB relational schema, resulting in heterogenous databases. Then,  present spatial databases as a special case of heterogenous databases and extend constraint query algebras (CQAs) with two additional spatial operators, proving that the resulting language is safe for linear constraints.
