What are the three types of models used for analysis and design in information systems development?

• Structured, Unstructured, Semi-structured

• Logical, Physical, Technical

• Narrative, Schematic, Formulaic

• Mathematical, Descriptive, Graphical

What is an event in the context of system analysis and design?

• A specific point in time

• A condition that triggers a response

• An action performed by the system

• A state of the system

What is the purpose of creating models in information system requirements?

• To clarify and refine design

• To limit communication with system users

• To increase system complexity

• To confuse system users

Which technique is used to identify use cases based on user goals?

• Temporal event checklist

• CRUD analysis technique

• Event decomposition technique

• External event checklist

What is the purpose of an entity-relationship diagram (ERD) in the traditional IS approach?

• To model software classes

• To create database design model

• To identify user goals

• To define system requirements

What is the main difference between data entities and objects in system modeling?

• Data entities are used in the design phase, objects are not

• Objects have behaviors and attributes, data entities do not

• Objects store information, data entities do not

• Data entities have behaviors, objects do not

What is the purpose of a class diagram in the object-oriented approach?

• To model things in the users' work domain

• To define system requirements

• To create database design model

• To model software classes

What is the purpose of identifying and analyzing events in system analysis?

• To define system requirements

• To increase system complexity

• To limit communication with system users

• To confuse system users

What is the purpose of identifying 'things' in the problem domain in system requirements?

• To define system requirements

• To model things in the users' work domain

• To model software classes

• To create database design model

What is the main purpose of the event table in system analysis and design?

• To catalog information about each use case

• To record system errors

• To document system complexity

• To list system requirements
