Phase 2 & 3

Question 1

When evaluating architecture, what is considered?

Answer 1

1 Modules/Components Themselves
2 Interactions between them
3 Integrations between them
4 How they fit in the environment

Question 2

What is the purpose of architecture?

Answer 2

1 Allow analysis of effectivness of design in meeting requirements
2 Consider alternative while change is relatively easy
3 Reduce risks associated with construction of the software

Question 3

What is the difference between architecture and design?

Answer 3

Design is an instance of architecture, similar to an object being an instance of a class

Question 4

What is the optimization problem in architecture?

Answer 4

To minimize changes, and to implement changes as quickly as possible

Question 5

Why is architecture important?

Answer 5

1 It provides a representation that facilitates communication among stakeholders
2 Highlights early design decisions
3 Model of system structure
4 Model of module/components working together

Question 6

What are the different architectural styles?

Answer 6

1 - Data centered (Data stores and access center of architecture)
2 - Data flow (Input->output transformation, pipe-and-filter pattern [pipe - sending data, filter - actions taken on data], single line transformation, batch sequential)
3 - Call and return (Main program/subprogram, remote procedure call)
4 - Object Oriented (Encapsulation, information hiding, class messaging)
5 - Layered (Components layered: Core - Control, utility - [sorts, common modules], application - control, UI - Boundary)

Question 7

What are the architectural (design) patterns?

Answer 7

1 Application-Specific Context (Limitations, Contraints)
2 Solution (General solution not specific)

Question 8

What are the types of architectural organization control?

Answer 8

1 Control

2 Data

Question 9

What does architectural Control organization encompass?

Answer 9

1 Transfer of control between user and application
2 Transfer of control between components
3 Synchronous or asynchronous operation

Question 10

What does architectural Data organization encompass?

Answer 10

1 Data transfer between components
2 Data transfer modes
3 Data and control interaction

Question 11

What are the architecture considerations?

Answer 11

1 Economy - Keep it simple
2 Visibility - Ensure reasons for decisions are obvious
3 Spacing - Avoid hidden dependencies
4 Symmetry - Maintain consistent and balanced attributes
5 Emergence - Maintain self-organized behavior and control (Event driven-defined behavior)

Question 12

What are the pieces of the Architexture Context Diagram?

Answer 12

1 Superordinate systems (Systems using the target system)
2 Subordinate systems (Systems used by target system, provide data/processing to complete target system functionality)
3 Peer-level systems (Interact on peer-to-peer basis, information either produced or consumed by peers/target system)
4 Actors (Entities that interact with target system by producing or consuming information)
