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”!

What 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 2ISA is about the 5th computing era : The Distribution one.
When the things are done in many computing units, of many kinds, in many places, available to anyone. When the centralization is no more possible.
This 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 axiomThe purpose of this blog is to build the best imaginable software architecture freed of any existing constraints.
The summary of this blog is organized hierarchically and chronologically. If you are not familiar with the ISA blog, it offers a more friendly navigation.
What 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.
