Providing a general purpose programming environment that supports the definition of, and exercises control over, the flow of execution of long-running activities is highly beneficial for a variety of client/server distributed data-intensive applications. In this paper, we present a Transaction-Oriented Work-Flow Environment (TOWE) for the programming of long-lived activities through a set of class libraries. The TOWE is based on an amalgamation of object-oriented programming with distributed interprocess communication concepts. The concurrency abstractions provided by TOWE are objects, acting like processes, and involve an asynchronous, location-independent, mode of process invocation coupled with data-driven synchronization of processes.
