Knowledge in software design

One of the fundamental skills to become a Software Quality Analyst is software design. Software design is the art and science of creating software structures that can be easily maintained, modified, and expanded over time.

To understand software design, it is important to understand design principles, which include cohesion, coupling, modularity, and abstraction. Cohesion refers to the extent to which the elements of a module are related to each other. Coupling refers to the extent to which a module depends on other modules. Modularity refers to the extent to which a system can be divided into independent modules. And abstraction refers to the extent to which a module is able to hide its internal details.

In addition to design principles, it is important to understand software design techniques, which include object modeling, data modeling, process modeling, and interface modeling. Object modeling is the technique of representing real-world objects in a software system. Data modeling is the technique of representing data in a software system. Process modeling is the technique of representing business processes in a software system. And interface modeling is the technique of representing the user interface in a software system.

In addition, it is important to understand software design tools, which include class diagrams, sequence diagrams, activity diagrams, and component diagrams. Class diagrams are used to represent classes and their relationships in a software system. Sequence diagrams are used to represent the interaction between objects in a software system. Activity diagrams are used to represent workflows in a software system. And component diagrams are used to represent the components and their dependencies in a software system.

In summary, software design is a fundamental knowledge to become a Software Quality Analyst. It involves understanding design principles, design techniques, and software design tools. With that knowledge, you can create software frameworks that can be easily maintained, modified, and expanded over time.
