5. A system for transforming attribute data at a source system having a first data model to a second data model associated with a target system, the system comprising: a first computer executing one or more query language reports to: extract attribute data from a source system, wherein a subset of the extracted attribute data is specific to an asset stored in the source system, wherein the asset is a class object with a unique set of attribute data, store the extracted attribute data from the source system in a transactional store, generate a report using the transactional store in order to assign the unique set of attribute data to represent the found asset in the source system, and identify that the asset stored in the source system is also stored in a target system when the unique set of attribute data found in the target system; a second computer executing a transformation engine program to: execute transformation rules for transforming the attribute data extracted by the first computer in a first format to a second format of a target system, wherein the transformation rules are specific to the first computer and the target system, and store the transformed attribute data into an entity relationship (ER) model used for exporting to the target system; and a third computer executing an export adapter program for exporting the transformed attribute data of the source system stored in the ER model to the target system.

The system of claim 5 , wherein the transformation rules are object-oriented transformation rules stored in an object-based data model in a memory.
