Abstract: Cross database model datum access with semantic preservation is provided. Data stored in a database under a particular database model can typically be inaccessible or not interoperable with data stored in another database model. A first datum of a first database model is transformed to an interim datum of an interim database model while preserving the data semantics associated with the first datum. Further, the second datum can be transformed into a third datum associated with a third database model, again while preserving the semantics. As such, data in a first silo can be accessed in a different silo while retaining semantic relationships. Further, the use of an interim database can reduce the processing needed to accomplish transforms between a planarity of database models.
