Abstract: A method and device for providing access, via a single point, to information stored on multiple data sources. One embodiment comprises a method in which first an interface (port) receives a call specifying a user identifier and a set of information from an application program. The set of information comprises a number of fields, where the fields correspond to information which is physically stored over a number of databases. Next, the method determines the location of the fields of information corresponding to the user identifier. Next, using the identifier which the application program passed in, the method retrieves the information. For example, the method may first retrieve information corresponding to a first field from a first database. Then, the method may retrieve information corresponding to a second field from a second database. Then, the method provides the information to the application program.
