Design

Question 1

List

Answer 1

Data flow diagram
Prototyping
Sequence diagram
State modeling

Question 2

Data flow diagram

Answer 2

Show where data come from,
Which activities process the data
And if the output results are stored or utilized by another activity or external entity

1. Externals: entity, sources, sink= destination of data
2. Data store
3. Process
4. Data flow

Question 3

Sequence diagram

Answer 3

Used to model the logic of usage scenarios by showing information passed between objects in the system through execution of the scenario

Lifeline
Activation box
Message: synchronous call, Asynchronous call

Question 4

Prototyping

Answer 4

Used to elicit and validate sh need through an interactive process that create a model or design of reqs
It also used to optimize user experience to evaluate design option, as a basic for development of the final biz solution

1. Prototyping approach
2. Prototyping examples: form study, usability visual, functional, proof of principle, proof of concept
3. Prototyping methods: story boarding, simulation, paper prototyping, workflow modeling

Question 5

State modeling

Answer 5

Used to describe and analyze the different possible states of an activity with the system
How that entity changes from one state to another state
And what can happen to the entity when it is each state

1. State
2. State transition
3. State diagram: show life cycle of one entity
4. State table: 2 dimension matrix show state and transition between them
