ISDS 406 BARLOW Final EXAM Questions and
Correct Answers| Latest Update 2024/2025
What are the steps of the design phase, and what is the final deliverable of the design
phase?
1. Determine system acquisition strategy (make, buy, or outsource).
2. Determine the technical architecture for the system.
3. Address security concerns and globalization issues.
4. Make hardware and software selections.
5. Determine the way that users will interact with the system (interface, inputs, and
outputs).
6. Design the programs for the underlying processes.
7. Design the way data will be stored
- Create final deliverable - the system specification
What are the three acquisition strategies? Under what circumstances would you
choose each one?
1. Custom development (build from scratch) in-house
2. Purchase software package (and possibly customize it)
- Install on our own computers, or
,- Obtain access from a software provider (SaaS)
3. Outsource development to third party, who might
- Build system from scratch for us, or
- Purchase software for us, customize and install it
What is an RFP? RFI? RFQ? What are their purposes?
Request for Proposals (RFP)
- Solicits proposals from vendor, developer, or service provider
- Explains the system to be built and criteria for selecting among applicants
Request for Information (RFI) - a shorter and less detailed version
Request for Quote (RFQ) - use when you just need a price
Alternative matrix: what is listed across the top row and what is listed down the first
column? How is the right alternative selected in a matrix? (hint: the one with the
highest weighted score)
Definition of architecture design
Plans for how the system will be distributed across computers and what hardware and
software will be used for each computer.
Objective of architecture design
Assign the software components of the information system to the hardware devices of
the system in the most advantageous way.
What are two major architectural components?
, 1. Hardware
2. Software
What are the four basic functions of software?
1. Data storage.
2. Data access logic: the processing required to access stored data.
3. Application logic: the logic documented in the DFDs, use cases, and functional
requirements.
4. Presentation logic: the display of information to the user and the acceptance of the
user's commands.
What are the three primary hardware components?
1. Client computers: Input-output devices employed by users (e.g., PCs, laptops,
handheld and mobile devices, smartphones)
2. Servers: Larger multi-user computers used to store software and data.
3. Network: Connects the computers.
In a client-server architecture, which of the four software types usually resides on the
client, which usually resides on a server, and which varies depending on the
architecture chosen?
- Client-server architectures balance the processing between client devices and one or
more server devices.
