Generation algorithms of Object id

5-Jan-2019

The object identifier production is one of the most important thing in an OO Architecture, and even more when it is a distributed one. This post is about some key items of the Identity axiom. Its major concerns are integrity, isolation and performance.

LL basics and syntax

16-Oct-2017

What are the major guidelines for LL? Simple (as Basic and PHP), Powerfull (like C++ or Smalltalk), Consistent (as OO is), Efficient (as C++ and Python), Dynamic but not messy, Seamlessly to suit to the whole software life cycle.

What to express ? The ISA roadmap

22-Mar-2017

After stating that LL is the language to express ISA, comes the time to define the content expressed: The whole software developpement stack (just this !). From the idea to the production, in going thru the coding, the testing and the other major tasks of our industry.That’s the opportunity to state the ISA software process steps and also the delivered artefacts.

Useless concepts

21-Jan-2017

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.

Object Oriented Guidelines

4-Dec-2016

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”!

The SOA paradigm case

31-Oct-2016

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!

The State axiom – Part 4

24-Jun-2016

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 ?

The State axiom – Part 3

1-Mar-2016

Third 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.

The State axiom – Part 2

28-Dec-2015

In 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.

The State axiom – Part 1

18-Dec-2015

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.
