� Process orientation in general and business process management in particular are parts of a larger development that has been affecting the design of information systems since its beginning: the evolution of enterprise systems architectures. � Enterprise systems architectures are mainly composed of information systems. These systems can be distinguished from software systems in the area of embedded computing that control physical devices such as mobile phones, cars, or airplanes.
� The guiding principle of this evolution is separation of concerns, a principle identified by Edsger Dijkstra and characterized by “focusing one’s attention upon some aspect. ” It is one of the key principles in handling the complexity of computer systems
�A software architecture defines a structure that organizes the software elements and the resources of a software system. Software elements and resources are represented by subsystems. � In a given software architecture, these subsystem have specific responsibilities and relationships to other subsystems.
� Service oriented computing is one of the major trends both in business engineering and software technology. The main idea of service orientation is to capture business relevant functionality as a service and provide sufficiently detailed information so that customers can use it. � This definition of service orientation goes well beyond service that are realized by software system.
� Steve burbeck, one of the early advocates of service-oriented architectures, define service-orientation as follows. � Services are loosely-coupled computing tasks communicating over the internet that play a growing part in business-to-business interactions. We reserve the term service-oriented for architectures that focus on how services are described and organized to support their dynamic, automated discovery and use. We don’t address systems based on manually hardwired interactions, such as those used in edi systems.

� ERP (Enterprise Resource Planning ) It handles the operational system to run the business and provides the required inputs to planning and control systems handled by the middle management. � CAD/CAM/CAE System) (Computer Aided Design /Manufacturing /Engineering It will provide the drawings and design engineering information to the ERP in its execution of manufacturing, purchase and inspection functions
� AMS (Attendance Management System) Attendance Management System keeps track of the employee related information for personnel planning, availability and scheduling DMS (Document Management System) The document management system is designed to keep important documents in the database for viewing, sending messages, and for documenting support in the transactions handled
� CMS (Communication Management System) The communication management systems are used for tracking the important resource for action. these resources are located, altered and advised to act from the location where they are SMS (Security Management System) The security management system handles the security, entry access requirement of the business operations. it may be a person, a vehicle, or material, its movement, availability and access if tracked, monitored, and guarded for security and safety.
