ABSTRACT:
Systems and methods consistent with the invention may include generating, via a processor, an entity relationship model to indicate a plurality of types of relationships between the entities, determining relationships between the database tables corresponding to the entities by using the entity relationship model, wherein the database tables are stored in a computer memory device, generating a graph based on the entity relationship model, generating sets of database elements representing the entities and corresponding data objects stored in the database tables, wherein the element sets are generated based on the generated graph, assigning ordering numbers to the database element sets and database elements included in the database element sets and executing the query transaction by using the data objects in an order based on the ordering numbers.
