The World Of Information Technology Is Full Of Specializations And Fields, Each Of Which Has Its Place, And The Combination Of These Roles Together Makes The Product Ready To Be Integrated And Accurate.

Software design is one of the most important jobs in information technology. In the simplest definition, software design is problem-solving and planning to build software. More precisely, software design is the process by which a programmer or a team of programmers designs a software feature that aims to accomplish predetermined goals using a set of primitive components subject to constraints.

A software designer or architect may encounter a problem that others have already seen and solved. Reusing these patterns can help speed up the software development process.

What is software design?

Software design is the process of predicting and defining software solutions to one or several problems. One of the main components of software design is analysis. The analysis is a part of the software development process that lists the specifications used in software engineering.

If the software is fully automated, a software design may be as simple as designing a flowchart of a sequence of programmed events. In addition, there are semi-standard methods, such as the same language and basic modeling concepts.

In any case, some documentation of this plan is usually a design product. The main difference between software analysis and software design is that a software analysis’s output is composed of more minor problems to solve the problem.

Depending on the environment, the design is often different, whether implemented through trusted frameworks or appropriate design patterns. Design examples include operating systems, web pages, mobile devices, and even the new cloud paradigm.

Software design is both a process and a model. The design process is a sequence of steps that enables the designer to describe all aspects of software development.

Creative skills, past experiences, a sense of what makes “good” software, and an overall commitment to quality are critical success factors for a good design. However, it is essential to note that the design process is not always straightforward; The design model can be compared with the house’s architectural design.

Points to pay attention to about design

In the design of a software component, many features must be taken into account. The most critical aspects are compatibility (the software can work with other products designed to be interoperable with another product), extensibility (new capabilities can be added to the software without significant changes to the underlying architecture), modularity (the software (‘s result, it is independent of independent components, leading to improved maintainability.

The components can then be implemented and tested individually before they are integrated into a desired software system, allowing division of labor to occur in a software development project.) , fault tolerance (software is resilient and able to recover from component failures), and maintainability (a measure of how well bugs can be fixed or functional modifications can be made. High maintainability can be a product of modularity and extensibility.

Why should software designers be proficient in modeling language?

A modeling language expresses information, knowledge, or systems in a structure defined by fixed rules. These rules are used to interpret the components in the form. The modeling language can be graphical or textual.

Among the graphic modeling languages ​​related to software design architecture description language (ADL) that is used to describe and represent the software architecture of a software system, the business process modeling notation (BPMN), EXPRESS, and EXPRESS-G (ISO 10303-1) is a general-purpose international standard for modeling. Is data, Elaborate Enterprise Modeling Language (EEML) used to model business processes in many layers, flowchart schematic representation of an algorithm or computational method, Fundamental Concepts of Modeling (FMC), which is modeling language for software-intensive system, IDEF family Mentioned modeling languages ​​(IDEF0 for performance modeling, IDEF1X for information modeling, and IDEF5 for ontology (science) modeling).
