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.

Have an underlying paradigm to help building ISA is a mean to promote coherence and consistency.
In this way it is easier to follow all the previously expressed wishes. It also gives guidelines for choosing among solutions in particular on reuse of an existing one.
Think and design ISA to be durable for several decades. The main design patterns should be incorporated as much as possible. This architecture should not limit itself in changes that it can elaborate to have good performances. And this in both dimensions hardware and software. Remain native : It is the condition to do at best of the possible. Define a solid base and then incorporate an extension mechanism.
Continue reading ISA Wish N°6 – Modern, performant and durableOne of firsts motivation of ISA is to unify the architecture and to make it simple in order to eliminate useless “expertise”.
ISA makes a break with the existent. Thus this architecture is free to make its choices. In other words, compatibility with actual IT is not a concern for ISA. This primary option eliminates the niches for geeks and experts.
