The choice of environmental and basic tools

The choice of environmental and basic tools

Almost any applications system that one might build today will exist in some environment over which the system developers do not have complete control. The days of writing codes in absolute binary and keying them in from the front panels of machines have departed, some recent excesses in the microcomputer community notwithstanding. Potentially, this means that choices must be made about what environments will be established to develop and operate the system - choices about hardware, operating systems, and languages. In many cases, the possible choices are so constrained by circumstances as to be trivial or non-existent. Worse, the constraints often arise from circumstances that have nothing to do with the requirements of or the intentions of the new integrated system, and will often lead to choices that are pathological for it. For the reader who has the luxury of making choices the two sections that follow are provided; for the reader who does not, these sections may be helpful in anticipating problems where choices are more constrained.
