The scope, background and foundations of ISA are now well established. It is time to examine the existing principles, the concepts and artefacts that are not useful for us. To reverse our point view in order to enumerate the existing things that must be avoided.

Foundations of ISA
ISA relies on the Object Oriented paradigm. Let me now join OO with our wishes. Some guidances emerge . The first one is, not surprisingly, “Everything in ISA is an Object”!
Continue reading Object Oriented GuidelinesWhat is really the SOA? Analyzing pros and cons, is this a concept usable for ISA? This post conclude that no, it isn’t. OO is more powerful and provides a wider consistancy.
However, some SOA central properties have to be incorporated in ISA. Let’s have a look to them!
Here I study the Class Object state axiom in the perspective of an incorporation in ISA. What’s about the Class life cycle ? And about the Versioning, the Grouping and the Delivery ?
Continue reading The State axiom – Part 4Third post on the object state axiom. Here I will speak about the state of the Class object and begin to define what it is. It is also question of immutability and of threaded objects.
Continue reading The State axiom – Part 3In this second post on Object state, we will see what are Fields, Relationships, Properties and Attributes; and why and how to put them all together.
Continue reading The State axiom – Part 2This post answers the question “What’s a State ?”. It also consider object life cycle and the basic Design Patterns. Finally, Eiffel’s advanced features around state are evoked.
Continue reading The State axiom – Part 1What are the Identity axiom consequences ? Here is a list of studied subject by this post: Addressing, Unitarity, Uniqueness, Ubiquity, Versioning.
Continue reading The Identity axiomWhat is an object ? This is the question this post answered by establishing an axiomatic: Encapsulation, Interface, Behavior, Identity and State.
This post also reveals what is there behind these axioms and begins to explore their implications.
In the perspective to give a basement to ISA, here is an exploration of pros and cons of major paradigms (No paradigm, Object Oriented, Sets (Relational) and Functional). To sum up the OO paradigm is retained for ISA. It is this approach that has made me discover the “Atom Oriented” possible paradigm.
