bcnQL: a query language for biochemical networks.

This paper proposes a graph data model that can represent information present in Biochemical Networks. The study presented in this paper also proposes a query language, called bcnQL, which empowers users to query entities, interactions, processes and pathways with arbitrary conditions. We then discuss the query-processing techniques, more specifically, the translation of bcnQL queries into G-algebra and a set of algebraic operators on graph objects. Some query examples are presented to demonstrate the applicability of the language for this specific domain. Finally, we provide details of a prototype implementation for the query language.
