US Patent 8626795 Dynamic data association

Methods, program products, and systems implementing dynamic data association are described. Relations between a first data item and a second data item can be created in an ad hoc manner. The first data item can include a row of data in a table in a relational database. The second data item can include a row of data in the same table, in another table in the relational database, or a document outside the relational database. Configurable metadata can be created to link the first data item and the second data item. The link can be directional. The configurable metadata can include data specified by a user. The configurable metadata can be stored in one or more system tables in the relational database. The configurable metadata can be specific to the user, or to a work group of the user. The configurable metadata can change when the first data item or the second data item is modified.
