Abstract: A method for implementing data model management at a first client application including: receiving a data model from a repository; generating a first delta from changes made to the data model; detecting whether a second delta, which is generated by a second client application from changes made to the data model at the second client application, is stored in the repository; and sending the generated first delta to the repository when the second delta is not stored in the repository. When the second delta is stored in the repository, the method includes steps of requesting the second delta generated by the second client application from the repository; generating a merged delta by merging the first delta with the second delta; and sending the merged delta to the repository. A system for implementing the data model management method.

Abstract: A method for conflict resolution includes converting a first plurality of transactions into a first plurality of derivative objects in a first derivative model wherein each of the first plurality of derivative objects comprises a corresponding first type indicator and converting a second plurality of transactions into a second plurality of derivative objects in a second derivative model wherein each of the second plurality of derivative objects comprises a corresponding second type indicator. The first plurality of derivative objects is compared with the second plurality of derivative objects, and it is determined whether one or more conflicts exist between one or more of the first plurality of derivative objects and one or more of the second plurality of derivative objects.
