A system and method for developing software using dynamic dual-mode model and data entry is presented. During development, a model developer uses a model window and an editor window to create a model-driven editor. The model window displays model data, and the editor window displays instances of the model data, which results in the model-driven editor. When the developer is ready to deploy the model-driven editor, the model developer simply inhibits the model window. Therefore, the models are not compiled during deployment and, in turn, the model developer does not need to test compiled code. Since the model-driven editor relies upon self-contained models, the models may be updated, added, or removed locally or remotely on an individual basis. In one embodiment, the end user is able to re-enable the model window in order to view model data.
