Computer systems and methods are provided for performing a database access. In one embodiment, a computer system is provided that comprises means for receiving and storing structural information, the structural information being descriptive of a number of objects, each of the objects having sub-objects, the structural information comprising a first table for each sub-object, each first table being identified by the sub-object name of its assigned sub-object, each first table comprising technical field names of fields of its assigned sub-object, and a second table for each sub-object, each second table being identified by the sub-object name of its assigned sub-object and comprising a sub-object name and a technical field name of one of the sub-objects from which its assigned sub-object depends for each of the technical field names of its assigned sub-object. In addition, the computer system may comprise means for assigning a unique identifier to each sub-object name identified by the structural information, means for storing a mapping table of sub-object names and unique identifiers, and means for requesting generation of a database table for each sub-object identified by the structural information, the database table of one of the sub-objects being identified by the unique identifier of the one sub-object and the database table of the one sub-object having the technical field names of the one sub-object.
