Difficulty: High

1.Software design should correspond to the analysis model: Often a design element corresponds to many requirements, therefore, we must know how the design model satisfies all the requirements represented by the analysis model.7084630105

2.Choose the right programming paradigm: A programming paradigm describes the structure of the software system. Depending on the nature and type of application, different programming paradigms such as procedure oriented, object-oriented, and prototyping paradigms can be used. The paradigm should be chosen keeping constraints in mind such as time, availability of resources and nature of user's requirements.

3.Software design should be uniform and integrated: Software design is considered uniform and integrated, if the interfaces are properly defined among the design components. For this, rules, format, and styles are established before the design team starts designing the software.

4.Software design should be flexible: Software design should be flexible enough to adapt changes easily. To achieve the flexibility, the basic design concepts such as abstraction, refinement, and modularity should be applied effectively.

5.Software design should ensure minimal conceptual (semantic) errors: The design team must ensure that major conceptual errors of design such as ambiguousness and inconsistency are addressed in advance before dealing with the syntactical errors present in the design model.

6.Software design should be structured to degrade gently: Software should be designed to handle unusual changes and circumstances, and if the need arises for termination, it must do so in a proper manner so that functionality of the software is not affected.

7.Software design should represent correspondence between the software and real-world problem: The software design should be structured in such away that it always relates with the real-world problem.

8.Software reuse: Software engineers believe on the phrase: 'do not reinvent the wheel'. Therefore, software components should be designed in such a way that they can be effectively reused to increase the productivity.
