Abstract: A system for data integration for a virtual environment, the system including: a game backend; a plurality of game clients, wherein each of the game clients comprise a client engine which is connected to the game backend; a plurality of data sources; and a data engine connected with the game backend and with the plurality of data sources, wherein the data engine retrieves data from the data sources and provides it to the game backend for use by the game clients, via the client engine. A method for data integration for a virtual environment, the method including: receiving a data request from a game client; retrieving data from a data source that complies with the data request or, if data is not available from the data source, synthesizing data; transforming the retrieved data into a format usable by the game client; and transmitting the data to the game client.
