EDITOR FOR THE CREATION AND MODIFICATION OF DATA MODEL METADATA

A data model metadata editor is described that may be integrated within a customer data platform. The editor enables a user to create and/or edit data model metadata by implementing a graphical user interface (GUI) that prompts the user to provide input and make selections in a manner that accords with rules concerning what information such metadata must include and how the contents of such metadata should be organized and formatted. Furthermore, the editor may perform syntax checking, validate such input and selections against the aforementioned rules, and flag any detected errors and/or potential problems to the user. Still further, the editor may apply the data model metadata (e.g., data schemas) to actual customer data and present the results to the user within the editor GUI so that the user can visually confirm that changes made to the data model metadata accord with the customer data.
