Collaboration: It represents the interaction between things that is done to meet the goal. 4. At that point of time, there were no standard methodologies to organize and consolidate the object-oriented development. 21. Transition . The two types of behavioral things are interaction and state machine. And each diagram manifests a different dimension, perspective, and view of the system. It depicts the interaction between two objects and the data flow between them. a) Structural things It is represented the same as that of a state machine diagram. The third section is used to describe the operations performed by the class. a) Activity diagram 13. It portrays a set of actions executed by a system to achieve the goal. c) Statechart diagram Relationships C. Diagrams D. All of the mentioned Explanation: All are the building blocks of UML which are further sub-categorized. c) Collaboration A. Relationships B. It is denoted by a dotted line with arrowheads on both sides to describe the relationship with the element on both sides. BUILDING BLOCKS OF UML The building blocks of UML can be defined as: Things Relationships Diagrams Things: Things are the most important building blocks of UML. Which things in UML are the explanatory parts of UML models? View Answer, 8. Design View. In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects.. 1. As UML describes the real time systems it is very important to make a conceptual model and then proceed gradually. Which of the following is not a standard stereotypes that will apply to the classes? Developed by JavaTpoint. c) Node diagram It shows several objects residing in the system. Which of the following is not a basic building block of ERDs? Its notation is as follows; Object:: An individual that describes the behavior and the functions of a system. Which of the following term is best defined by the statement:”a structural relationship that specifies that objects of one thing are connected to objects of another”? Use cases . There are four types of relationships given below: Dependency: Dependency is a kind of relationship in which a change in target element affects the source element, or simply we can say the source element is dependent on the target element. What refers to the value associated with a specific attribute of an object and to any actions or side? a) Deployment diagram Classes and interfaces are a part of Join our social networks below and stay updated with latest contests, videos, internships and jobs! Component: It represents the physical part of the system. Rules controlling how the blocks are put together (the syntax) 3. A constraint extends the _____ of a UML building block. It keeps a record of several distinct states of a system component. The conceptual model of UML can be mastered by learning the following three major elements − UML building blocks; Rules to connect the building blocks; Common mechanisms of UML; This chapter describes all the UML building blocks. • Collaboration - a collection of UML building blocks (classes, interfaces, relationships) that work together to provide some functionality within the system. b) Sequence diagram It is symbolized as a dotted ellipse with its name written inside it. The UML is more than just a graphical language. Entity-relationship diagrams (ERDs) are similar in content and purpose to Unified Modeling Language (UML) Class diagrams. b) Aggregation Here’s the list of Best Reference Books in Software Engineering. Duration: 1 week to 2 week. Stated formally, the UML is for: Visualizing, Specifying, Constructing, and Documenting. Each symbol has a different meaning in the context of the UML diagram. b) attribute They include class, object, interface, node, collaboration, component, and a use case. d) All of the mentioned a) True Which of the following is not one of the building blocks used for creating UML class diagrams? d) Class The diagrams are the graphical implementation of the models that incorporate symbols and text. Learning to apply the UML effectively starts with forming a conceptual model of the lan-guage, which requires learning three major elements: the UML’s basic building blocks, the rules that dictate how these building blocks may be put together, a) Activity a. Which of the following is a building block of UML? State Machine: It defines a sequence of states that an entity goes through in the software development lifecycle. View Answer, 12. Node: A physical element that exists at run time. Grouping things 4. A. It is an object that interacts with the system, for example, a user. Activity Diagram: It portrays all the activities accomplished by different entities of a system. So far, the UML diagram has become one of the most common business process modeling tools, which is also highly significant to the development of object-oriented software. What can be requested from any object of the class to affect behavior? In UML, a note is the only Annotational thing. Entities c. Attributes d. Relationships CORRECT ANSWER : semantic The structural things are class, interface, collaboration, use case, active class, components, and nodes. Conceptual model of UML can be better understood by learning the following three major elements : UML building blocks Rules to connect the building blocks Common mechanisms of UML 5. d) Annotational things © Copyright 2011-2018 www.javatpoint.com. This set of Software Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Building Blocks of UML”. It plays an essential role in developing UML diagrams.
