摘要：
The present invention relates to a computer system comprising:
means (306, 308) for receiving and storing structural information (312), the structural information being descriptive of a number of objects (104), each of the objects having sub-objects (106, 108,...), the structural information comprising a first table (112) 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 (114) for each sub-object, each second table being identified by the sub-object name of its assigned sub-object, each second table 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,
means (324) for assigning a unique identifier to each sub-object name identified by the structural information,
means (308) for storing a mapping table (310) of sub-object names and unique identifiers,
means (326) for requesting generation of a database table (330) 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 of the sub-object having the technical field names of the one sub-object.
