Although, many applications use unstructured meshes, there is no specialized mesh database which supports storing and querying mesh data. Existing mesh libraries do not support declarative querying and are expensive to maintain. A mesh database can benefit the domains in several ways such as: declarative query language, ease of maintenance, etc. In this(More)
Despite ubiquitous usage of unstructured mesh in many application domains (e.g., computer aided design, scientific simulation, climate modeling, etc.), there is no specialized mesh database which supports storing and querying such data structures. Existing mesh libraries use file-based APIs which do not support declarative querying and are difficult to(More)
In this paper, we present a topological neighborhood expression which allows us to express arbitrary neighborhood around cells in unstructured meshes. We show that the expression can be evaluated by traversing the connectivity information of the meshes. We implemented two algebraic operators which use the expression to compute neighbors of cells and(More)
To understand and improve processes in organizations, six key questions need to be answered, namely, what, how, where, who, when, why. Organizations with established processes have IT system(s) that gather(s) information about some or all of the key questions. Software organizations usually have defined processes, but they usually lack information about how(More)
