Oriented Services Software Architecture Principles And Examples

The momentum of innovation always originates from man's upgraded quest and new hope. It is known that the computer's coming greatly changes our society and life. Unfortunately, the productivity of software still remains the low level stage. Worse still, software crisis is coming. Software projects are notoriously behind schedule and over budget. The cost of owning and maintaining software becomes more and mores expensive. Three quarters of all large software products delivered to the customer are failures that are either not used at all, or do not meet the customer's requirements. The first goal of this dissertation is to resolve the software crisis and second is to provide software's mass production model. In this model, the manufacture of software often uses standardized components and assembly-line techniques.To resolve software crisis, arrive at the mass production stage, it is needed not only innovation of technology but also management. In this situation, man begins to use engineering methods and principles to instruct software development. In this dissertation, it's focused in software architecture research, and finally provides an easy developing and maintenance and highly reusing Service-Oriented Architecture. Service-oriented architecture (SOA) is essentially a collection of services. It is an application architecture within which all functions are defined as independent services with well-defined invokable interfaces which can be called in defined sequences to form business processes. It is really platform-independent and language-independent. This dissertation mainly analyzes the architecture and a paradigm and makes a conclusion that SOA is an excellent solution to resolve these problems.
