Abstract: Disclosed herein are system, method, and computer tangible medium embodiments for generating a relational database model from a model view that provides an estimate for generating query plan for a query on the model view, according to an embodiment. A join model of a model view set on one or more database tables is received. At least one index conversion of the join model is performed, where the index conversion converts at least one index in the join model into at least one leaf node in a relational model tree. At least one join conversion of the join model is performed where the at least one join conversion generates a node in the relational model tree that joins a first and second leaf nodes in the relational model tree. A requested parameter conversion is performed, where the requested parameter conversion includes an attribute or key figure requested by a query.

Abstract: A method, computer program product and system are provided. The method, computer program product and system execute a process for storing an object in an object container that is stored in a persistency of a disk storage. The object container has size criteria whereby objects meeting the size criteria of the object container can be assigned to the object container. The object container can facilitate storing multiple objects to optimize disk storage usage by facilitating the assigning of multiple objects to the same disk storage page.
