Abstract: Techniques for automatically migrating documents from a document database to a relational database are provided. In one technique, it is determined whether a set of documents, from a document database system, can be stored in a relational database system. If so, one or more entities to be normalized are identified based on a hierarchical structure of the set of documents. One or more scripts are generated based on the identified one or more entities. In a related technique, a set of documents from a document database system is stored. It is validated that the set of documents can be converted to one or more duality views. Data of the set of documents is normalized for storing in a relational database system. A script is generated that, when executed, generates the one or more duality views.

Abstract: JSON Duality Views are object views that return JDV objects. JDV objects are virtual because they are not stored in a database as JSON objects. Rather, JDV objects are stored in shredded form across tables and table attributes (e.g. columns) and returned by a DBMS in response to database commands that request a JDV object from a JSON Duality View. Through JSON Duality Views, changes to the state of a JDV object may be specified at the level of a JDV object. JDV objects are updated in a database using optimistic lock.
