Service granularity generally refers to the size of a service. The fact that services should be large-sized or coarse-grained is often postulated as a fundamental design principle of service oriented architecture (SOA). However, multiple meanings are put on the term granularity and the impact of granularity on architectural qualities is not always clear. In(More)
Enterprises are living things. They constantly need to be (re-)architected in order to achieve the necessary agility, alignment and integration. This paper gives a high-level overview of how companies can go about doing ‘enterprise architecture’ in the context of both the classic (isolated) enterprise and the Extended Enterprise. By discussing the goals(More)
In this paper we argue that there exist two basic forms of business-to-business integration (B2Bi), namely, extended enterprise integration and market B2Bi. The paper at hand clarifies the meaning of both concepts, shows that the difference between both is fundamental, and discusses the consequences of the difference in the realm of Web services(More)
Object Orientation has as primary goal to improve the software construction process. Object Oriented analysis, design and software construction should yield software of a high quality: software that is reliable, maintainable, extensible, adaptable. However, delivering large OO software systems in a qualitative way is a significant challenge. Scaling up(More)
Object oriented models model structural and behavioural aspects of objects in the Universe of Discourse. As the dynamic aspects of objects include parallelism and synchronisation of object life cycles, conceptual schemas must be verified for problematic behaviour like deadlock. In this paper we will present fragments of a method for object oriented analysis(More)
The "IS A"-relationship and the mechanism of inheritance are powerful concepts that help to reduce complexity of models and redundancy in specifications. However, in the area of conceptual modeling, it seems that current Object Oriented Analysis methods put most emphasis on the structural aspects of the "IS A"-relationship while inheritance and sharing of(More)
