Data model versioning for document databases

摘要

A data model versioning method may read a first version tag associated with a document database. The method compares the first version tag to a second version tag associated with a current document template of an application, the second version tag indicating a document format used by the current document template for documents created by the application. When the first version tag does not match the second version tag, the method performs a version migration operation to update a document format of documents in the document database.
