440+ Software Design Modeling (SDM) Solved MCQs

Software design modeling (SDM) is the process of creating a representation or blueprint of a software system. It involves identifying and specifying the components that make up the system and their relationships, as well as defining the interfaces between those components.

There are many different approaches to software design modeling, and the specific techniques and tools used can vary depending on the specific needs and constraints of a given project. Some common techniques and tools include:

UML (Unified Modeling Language): UML is a standardized language for creating graphical models of software systems. It includes a set of symbols and notation for representing different types of components, such as classes, objects, and relationships.

Class diagrams: Class diagrams are a type of UML diagram that shows the structure of a system in terms of the classes and their relationships. They can be used to visualize the static structure of a system, as well as the relationships between different classes.

Use case diagrams: Use case diagrams are another type of UML diagram that show the interactions between a system and its users. They can be used to identify and document the specific actions that a system is designed to perform, as well as the actors that interact with the system.

Prototyping: Prototyping is a technique for creating a preliminary version of a software system, typically for the purpose of testing and evaluating its functionality. Prototyping can be used to quickly explore and iterate on different design ideas and can help to identify and address any potential issues before building the final version of the system.

Software design modeling is an important part of the software development process, as it helps to define the structure and behavior of a system and ensure that it meets the needs of its users. It can also help to identify potential issues and mitigate risk before implementing the final version of the software.
