When making calls to a supplier, a software module should not violate the supplier's preconditions. Design by contract can also facilitate code reuse, since the contract for each piece of code is fully documented. The contracts for a module can be regarded as a form of software documentation for the behavior of that module.
Broadly, functional requirements define what a system is supposed to do and non-functional requirements define how a system is supposed to be.Functional requirements are usually in the form of "system shall do <requirement>", an individual action or part of the system, perhaps explicitly in the sense of a mathematical function, a black box description input, output, process and control ...
Companies wanting to conduct Test and Learn must mobilize, track and analyze site and customer data at very granular levels. This can often be a massive and expensive undertaking. Increasingly however, an exponential increase in computing power, and corresponding decrease in its cost, have made testing more accessible.
Program comprehension (also program understanding or [source] code comprehension) is a domain of computer science concerned with the ways software engineers maintain existing source code. The cognitive and other processes involved are identified and studied. [1] The results are used to develop tools and training. [2]
The term "inversion" is historical: a software architecture with this design "inverts" control as compared to procedural programming. In procedural programming, a program's custom code calls reusable libraries to take care of generic tasks, but with inversion of control, it is the external source or framework that calls the custom code.
In systems engineering and software engineering, requirements analysis focuses on the tasks that determine the needs or conditions to meet the new or altered product or project, taking account of the possibly conflicting requirements of the various stakeholders, analyzing, documenting, validating, and managing software or system requirements.
A re-order buffer (ROB) is a hardware unit used in an extension to Tomasulo's algorithm to support out-of-order and speculative instruction execution. The extension forces instructions to be committed in-order.
The Zachman Framework of enterprise architecture. The Zachman Framework is an enterprise ontology and is a fundamental structure for enterprise architecture which provides a formal and structured way of viewing and defining an enterprise.
