Selection and methods
Software design and portability

When designing software, it's important to make the right choices and use programming and development methods that increase its portability. Let's summarize them before coming back to them in more detail:

• choice of target platforms: not all software needs to be available on all architectures and operating systems;

• the choice of system integration level: depending on certain constraints, usually performance, it may be necessary to use the specific functions of an operating system;

• choice of tools: an application often uses software tools, and it is important to choose them carefully;

• development methods: this category covers the technical aspects of software engineering: choice of languages, programming style, program organization, architecture...
