Design by contract (DbC), also known as contract programming, programming by contract and design-by-contract programming, is an approach for designing software. It prescribes that software designers should define formal , precise and verifiable interface specifications for software components , which extend the ordinary definition of abstract ...
With respect to regulation, two terms are defined: Postmarketing requirements are studies and clinical trials that sponsors are required to conduct and postmarketing commitments are studies or clinical trials that a sponsor has agreed to conduct, but that are not required by a statue or regulation.

In software engineering, a software design pattern or design pattern is a general, reusable solution to a commonly occurring problem in many contexts in software design. [1] A design pattern is not a rigid structure that can be transplanted directly into source code. Rather, it is a description or a template for solving a particular type of ...
In software engineering, concurrency patterns are those types of design patterns that deal with the multi-threaded programming paradigm. Examples of this class of patterns include: Active object [1] [2] Balking pattern; Barrier; Double-checked locking; Guarded suspension; Leaders/followers pattern; Monitor Object; Nuclear reaction; Reactor ...
David E. DeLano of C++ Report praised the first volume, writing, "Overall this text is good and I recommend it as an addition to any collection of books on patterns." He said "some of the language and grammar usage feels awkward to the reader" and some of the book has "stiffness and flow problems". [1]
Blackboard design pattern Provides a computational framework for the design and implementation of systems that integrate large and diverse specialized modules, and implement complex, non-deterministic control strategies Chain-of-responsibility pattern Command objects are handled or passed on to other objects by logic-containing processing ...
The indirection pattern supports low coupling and reuses potential between two elements by assigning the responsibility of mediation between them to an intermediate object. An example of this is the introduction of a controller component for mediation between data (model) and its representation (view) in the model-view-controller pattern.
His pattern form, the "Coplien Form," [2] is a simplified way to structure a pattern in preparation for writing a more literate version in Alexandrian form. Together with Trygve Reenskaug, he was a principal in the design of the data, context and interaction (DCI) paradigm.
