The paper proposes a new meta-architecture as a reference model for developing service-oriented systems and applications. The seven-layer meta-architecture is called STCBMER (Smart Client-Template-Bean-Controller-Mediator-Entity-Resource). The purpose of it is to reduce software complexity and ensure the quality of adaptability defined as the degree to which an information system or application is difficult to understand, maintain and evolve. The main difficulty stems from complex interactions (dependencies) between system elements. The dependencies can be minimized if the system under development adheres to the architectural design and can be verified by analysing the implementation code. The paper reinforces the proposition that an architectural intent for adaptive complex systems requires some sort of hierarchical layered structure (according to the holon abstraction as an approach to restraining software complexity).

Abstract-The last decade was a time of a very successful growth of Electronic Markets (EMs). EM is an electronicallysupported system which is rather focused on selling physical goods. Electronic Service Market (ESM) is a special case of EM, focused on selling services. The raising business of running ESM seems to be the next possible evolution of the classic EM, and in last few years, several ESM projects were started by various organizations. This paper presents the essential Functional and Architectural Requirements needed in ESM system. The way of their transformation into the architecture of real-life application based on STCMBER meta-architecture was presented. The proposed architecture was validated in the series of pilot implementations performed in compliance with Consortium Research method.

There is a wealth of evidence that contemporary landscape of software development has been resisting the disciplined, rigorous, formally managed, architecture-driven, forward-engineering practices. The whole field of traditional software engineering needs a re-definition alongside the practices widely used in production of modern software systems, in particular service-oriented cloud-based applications. This paper argues that contemporary software engineering must re-focus and redefine its theoretical foundations and base it on acknowledgment that quality software and systems can (and by and large should) be constructed using principles of resultant architectures and roundtrip engineering.
