Methods and systems are disclosed for generating common objects in a universal format. A stream of data objects is received from each of a plurality of databases. Each stream of data objects includes objects represented in a disparate data type from objects in other streams. A plurality of agents are generated and configured to process data objects of a particular format. For each object, a source database of the data object is identified. An agent of the plurality of agents can be selected based on a database type of the source database. The agent generates a common object from the data object that is represented in a universal format. The common object is stored a graph database of common objects.
