Abstract: A model edit control system controls editing of a data model. A model repository manager allows multiple users to copy a stored model stored in a repository for executing changes on multiple model copies in parallel. An action log manager crates a model action log for the stored model and tracks actions executed on the stored model. The action log manager also creates a current action log for each model copy to record actions executed on the model copy. A model merger manager merges the model copies into the stored model in the repository, by playing the actions in the current action log against the stored model in the repository.

Abstract: A system for data modelling is provided. The system comprises a model repository for storing one or more data models, a model partitioning module for segmenting a data model into smaller data models, and a model linking module for connecting two or more data models stored in the model repository.

Abstract: A system for capturing transformations performed against a baseline data model is provided. The system comprises an action interceptor for capturing a transformation performed against the data model, an action logging repository for storing the captured transformation into an action log, and an action log scripting unit for playing the action log against a copy of the baseline data model.
