Disclosed are systems and methods which provide an interface for disparate software applications using a decentralized adapter architecture. Embodiments provide an interface between software applications using multiple adapters, wherein at least one adapter is associated with each end of a software application information communication link. Adapters are adapted for proprietary data communication with one or more application and for data communication with other adapters using protocols common to each such adapter. Information communication provided between software applications using adapters may be provided in batch mode, in real-time mode, or in both batch and real-time modes. Adapters may be associated with an enterprise function or "business process" basis. Accordingly, a plurality of adapters may be utilized with respect to any particular software application. Likewise, a plurality of software applications may be associated with any particular adapter.
