The differences between timing diagram and sequence diagram are the axes are reversed so that the time are increase from left to right and the lifelines are shown in separate compartments arranged vertically. While preparing event oriented diagram one must take into consideration following questions concerning the sequence of events: 1. Class diagrams basically represent the object-oriented view of a system, which is static in nature. Answer - Click Here: (C)request link. A : C attribute of class 4. A class diagram can curtail maintenance time. A) Sequence Diagram + Collaboration Diagram B) Activity Diagram + State Chart Diagram C) Deployment Diagram + Collaboration Diagram It shows the state of the object between two horizontal lines that cross with each other each time the state changes. In an object diagram, an object is represented as a rectangle with two compartments. Course Hero is not sponsored or endorsed by any college or university.

A directory of Objective Type Questions covering all the Computer Science subjects. The object-oriented development life cycle is which of the following? UML class diagram notation was developed to represent these programs visually. In UML 2 there are two basic categories of diagrams: structure diagrams and behavior diagrams. The latest version (UML 2.5) has 14 different diagram types which are roughly divided into two categories: behavioral andstructural diagrams. Class diagrams. Analysis, design, and implementation steps in the given order and using multiple iterations. â¢ Translate between UML class diagrams and equivalent Java code. To better represent a time plane, UML 2.0 models timing diagrams as two-dimensional diagrams, with an x-axis and a y-axis. ... What part of a sequence diagram represents the time during which the object above it is able to interact with the other objects in the use case? Real-time systems, for example, have to complete certain processes within a certain period of time. Which of the following diagram is time oriented?
