Below are some important UML interview questions which are asked in most MNC company interviews for beginners or professionals.
21. What is SDLC?
SDLC is Software Development Life Cycle. SDLC of a system included processes that are Use case driven, Architecture centric and Iterative and Incremental. This Life cycle is divided into phases. Phase is a time span between two milestones. The milestones are Inception, Elaboration, Construction, and Transition. Process Workflows that evolve through these phase are Business Modeling, Requirement gathering, Analysis and Design, Implementation, Testing, Deployment. Supporting Workflows are Configuration and change management, Project management.
22. What is modeling? What are the advantages of creating a model?
Modeling is a proven and well-accepted engineering technique which helps build a model. Model is a simplification of reality; it is a blueprint of the actual system that needs to be built. Model helps to visualize the system. Model helps to specify the structural and behavior of the system. Model helps make templates for constructing the system. Model helps document the system.
23. What are the different views that are considered when building an object-oriented software system?
Normally there are 5 views. Use Case view - This view exposes the requirements of a system. Design View - Capturing the vocabulary. Process View - modeling the distribution of the systems processes and threads. Implementation view - addressing the physical implementation of the system. Deployment view - focus on the modeling the components required for deploying the system.
24. What are diagrams?
Diagrams are graphical representation of a set of elements most often shown made of things and associations.
25. What are Messages?
A message is the specification of a communication, when a message is passed that results in action that is in turn an executable statement.
