The Service Oriented Business Process and Separation of Concerns - Modelling paradigms for Architectures and Business Processes

This paper deals with the contemporary concern of business service-orientation. The paper suggests that service-oriented Business Information Systems Development (BISD) permits quality aspects, -“ilities” e.g.; maintainability and modifiability, of BISs and BISD. In addition, this paper departs from viewing a Business Information System (BIS) as services and suggests Separation of Concerns (SoC) as a prerequisite for achieving a well formed digital ecosystem. Besides knowledge transfer the purpose of this paper is to indicate the
importance of architecture incorporating SoC when service-orienting a business with the contemporary Service Oriented Architecture (SOA). By realizing business logic service orientation in a nationwide research project our conclusion indicates that separate
implementation of decision logic and process logic provides two different species of digital services implementing SoC. Consequently, responsible and eligible digital services become deliverables, service-orienting a part of a business representing vital quality aspects of ISD. The viability of separate digital services ensuring SoC facilitates the well-formed digital ecosystem i.e. the service oriented business process and business logic reusability and
modifiability. The originality of this paper is based on a non-technical departure of SOA and on separation of process and decision logic as a mean to decreased child deaths due to
