Abstract
The present invention relates to a method of executing an export process for an automated meta model driven export of entity parts from a source data base (10), wherein the meta model specifies an abstract model of the source data base (10) and comprises a description of an entity part and/or a reference relationship between entity parts being resolvable from a referencing entity part to a referenced entity part. The method comprising the steps identifying (S14) a set of entity parts being identifiable outside the source data base (10) by a public key, an internal key, or a mixture of a public key and an internal key as first level entity parts, supplementing (S16) the set of first level entity parts by a set of second level entity parts being referenced by the first level parts according to at least one reference relationship described in the meta model, and writing (S18) export data for the set of first level parts and the set of second level parts into an export file. The present invention also relates to a method of executing an import process for an automated meta model driven import of entity parts from a source data base (10) to a target data base (12).
