Software engineering factors related to…, The AIDA Approach to Educational Software Portability. The whole software design process has to be formally managed long before the first line of code is written. Porting is no more than transferring specified directories and their contents. Many language specifications describe implementation defined behaviour (e.g. right shifting a signed integer in C can do a logical or an arithmetic shift). Reinstalling a program from distribution files on another computer of basically the same architecture. Non-web programs, installed upon a computer in the normal manner, can have more control, and yet achieve system portability by linking to portable libraries providing the same interface on different systems. Software engineering factors related to portability—such as factors related to the student-computer interface, authoring, and choice of design model—are also discussed. Such a program can run in a common web browser. In software engineering, porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program was originally designed for. In these cases there is usually no need for detailed adaptation of the software for the system; it is distributed in a way which modifies the compilation process to match the system. See portable application. Scalability in software engineering refers, normally, to designing software systems in such a manner that, as the number of users of the system increases (even by factors of 100x or more), the software will continue to function with comparable response times. Software Reliability is an essential connect of software quality, composed with functionality, usability, performance, serviceability, capability, installability, maintainability, and documentation. In earlier days source code was often distributed in a standardised format, and could be built into executable code with a standard Make tool for any particular system by moderately knowledgeable users if no errors occurred during the build.
