Systems and methods are described for performing a schema-based data transfer between a database associated with a data-based application and a document associated with a document application. In one implementation, connection information established during an initial schema-based data transfer between the database and the document is maintained in association with the document. This connection information is then used to facilitate subsequent updating of the document based on information currently residing in the database as well as subsequent updating of the database based on information currently residing in the document in a manner that is highly automated and easy to use.
