CS504: SOFTWARE ENGINEERING – 1
What is Software Engineering?
Software engineering is a detailed engineering study in the design, development, and maintenance of software. Although Software Engineering is defined as the process of analyzing user needs and then designing, developing, and evaluating software programs that will meet those needs.
Software Engineering as defined by IEEE:
Let’s take a look at some of the definitions of software engineering. Software Engineering as defined by IEEE (International Center for Electrical Engineering and Technology). IEEE is a real center for computer-related issues. “The use of a systematic, disciplined, and efficient approach to software development, operation and maintenance; that is, the use of engineering in software. “
Software Engineering Phases
There are four basic stages of software development shown in Figure 4. Vision: Here we decide why we do this and what business goals we want to achieve.
Here we really notice or change the view developed in the first paragraph. Here we decide what activities and objects are involved.
At this stage, we are trying to find a solution to the problem for technical reasons and support our actual implementation in it. This is the phase in which a new problem-solving system is developed in the first phase.
If there are advanced systems available where our new system should be integrated then those systems should also be part of our new system. All of those existing systems integrate with our new system at this stage.
After successfully going through the last three stages, we are actually a new system is applied to the user area and that status is called quo status. But once we find new needs, we have to change the existing situation.
Some Other Terminologies Used in Software Engineering
Prototyping is another method that can be used to reduce customer dissatisfaction in the required category. The idea is to capture the user’s view of the product and get an early response from the user to ensure that the developers’ team understands the requirements. This is used when there is uncertainty about the requirements. Sometimes, even the customer does not know what they really need. This happens when there is no handmade solution.
Integrating the independent rating of a module or component. Loose connectivity means that different parts of the system have less or less reliance on others. Therefore, changes in one component will have a limited impact on other components.
Cohesion is a measure of the degree to which the module elements interact with the performance. It is the level at which all the elements focused on performing a single function are contained in the section. Basically, assembling the inner glue that keeps the module together.
The process of developing software products using software engineering principles and methods is called software evolution. This includes initial software development and maintenance and updates until the desired software product is developed, which satisfies the expected requirements.
Abstraction and Encapsulation
Abstractions are a way in which we build a business model based on its key features and ignore insignificant details. The goal of capturing things also helps us to manage the natural complexity of the system by allowing us to focus on its important external aspect, while at the same time, hiding its internal complexity. Hiding internal information is called encapsulation. In fact, the exclusion is a special issue of the separation of anxiety. In this case, we separate the concerns of business users who only need to understand the external interface without having to worry about its actual use.
Source and sink analysis
Once the requirements have been documented using any of these analytical models, independent verification is required to ensure the completeness and consistency of the requirements adopted by these models. The process of verifying needs includes careful analysis of resources and immersion of information.
A participant describes the requirements (requirements, barriers) that must be included as a system function. These can be processes that generate specific information that a system may or may not process. The sources of demand are from where the corresponding business process is started. In this sense, one has to trace the origin of the need and go back to its origin to see who participated in its initiation. It can be a person, organization, or foreign business that initiates an action and the system responds by completing that action.
A sink is a consumer of certain information. It is that business that provides the rational conclusion of the business process. Thus, ‘needs sinks’ is a concept that helps to identify individuals, organizations, or external systems that are experiencing some function in the system. These are logical conclusions of needs, or when all requirements are met.
For example, we might consider an app user receiving a report in the system. In this case, the user, when reviewing the report, becomes the domain of that report. Therefore, when analyzing the immersion requirement of a report usage, the analyst will naturally point to the user who will receive that report.
