Architectural styles defined

There are many different architectural views of a system, calling for different kinds of elements. These elements include hardware and networks, packages and their structures, object types and relationships, concurrent processes and threads, tables and columns, and the patterns that dictate how they are to be used. An architectural style, or type, defines a consistent set of elements and rules for their use. 

Using components and connectors to define architectural styles was introduced in [Allen94] and elaborated in [Shaw96], Component connectors appear in a number of patterns in [PLoP]. Our definition of them in terms of actions appeared in [Wills97a]. 

Abstract. Service-oriented architectures define an architectural style for the construction of a heterogeneous application landscape. By abstracting services, business processes are decoupled from the underlying applications. This section describes how the results of the IMPROVE subproject 13, related to the model-driven development process for wrapper construction, are transferred and extended to the area of business process applications. We present an approach which yields a prototype to formally specify service descriptions and service compositions. This prototype makes it possible to evaluate and explore service-oriented architecture concepts. 

The actual relationships defined in the system design are called the architecture. There are two extremes that are considered in system architecture, integrated and modular. Modular systems are made up of components or modules that have clear interfaces with each other, and are easily visualized as systems. Integrated products, on the other hand, appear to be a single element, with what interfaces exist being so soft and blurred as to be hard to identify. Each of these styles has its advantages. Integration allows the device to be technically more efficient. With the overall device optimized, there is no loss due to inefficiencies of connections, etc.
