The facade pattern (also spelled façade) is a software design pattern commonly used in object-oriented programming.Analogous to a façade in architecture, it is an object that serves as a front-facing interface masking more complex underlying or structural code.
An application programming interface is a form of interface for a software system, in that it describes how to access the functions and services provided by a system via an interface. If a system producer wants others to be able to use the system, an ICD and interface specs (or their equivalent) is a worthwhile investment.
The adapter [2] design pattern is one of the twenty-three well-known Gang of Four design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse. The adapter design pattern solves problems like: [3]
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 .
The data flow diagrams allocate control input, processing and output along three separate modules. The interface design describes internal and external program interfaces, as well as the design of the human interface. Internal and external interface designs are based on the information obtained from the analysis model.
The N 2 diagram has been used extensively to develop data interfaces, primarily in the software areas. However, it can also be used to develop hardware interfaces. The basic N 2 chart is shown in Figure 2. The system functions are placed on the diagonal; the remainder of the squares in the N × N matrix represent the interface inputs and ...
