Toward unstructured mesh algebra and query language
Alireza Rezaei Mahdiraji · 2014
Although several application domains use unstructured meshes as first-class citizen, there is no dedicated database system which offers querying and manipulation of such objects via a declarative query language. A declarative query language allows users to describe their information needs as easy as natural language. In this paper, we present our initial work on unstructured mesh algebra. The algebra is an abstract mathematical language which allows manipulation and retrieval of data from a mesh dataset. The algebra creates the base for designing a declarative query language for the meshes and allows al- gebraic optimization. We describe the semantic of primitive operators, special cases, few algebraic transformation, and the future challenges.
