In which category of the DIKW hierarchy would BI be located? - correct answer Knowledge
DIKW - correct answer Describes the transition for data, information, knowledge to wisdom
D in DIKW - correct answer Data, inputs directly received by a computer
I in DIKW - correct answer Information, transform data into a useful form (using algebraic laws)
K in DIKW - correct answer Knowledge, is gained experience from using information (knowing which algebraic laws to use in a given situation)
W in DIKW - correct answer Wisdom, social setting to knowledge or the understanding of "why". Wisdom is the ultimate goal for a human in that it improves the person's ability to function in the modern world and to make informed decisions that take into account beliefs and values.
Which system requirement is an example of considering user needs in the design of an information system? - correct answer Allowing easy access to customer account information
Which field must contain a unique value in order for a relational database table to function? - correct answer Primary key
N-Tier - correct answer Indicate that the number of tiers a system will be broken down into will vary between different software development projects. In typical n-tier development projects, the tiers are divided between the presentation tier, the logic tier, and the data tier
Presentation N-Tier - correct answer User interface is developed
Logic N-Tier - correct answer Where the system performs its logic processing
Data N-Tier - correct answer Where data is stored, retrieved, and updated from database tables
Benefit of separating database from application? - correct answer Data can change without the need to change the application, scale more easy, removes the need for users to interact directly with data
How does a compiler work? - correct answer It takes the most recent instructions and translated them into machine language
What is the characteristic of high-level languages? - correct answer Language translator programs are required
Which is a type of two-factor authentication? - correct answer Biometrics
End users assisted by developers; systems tested with simulated data - correct answer Alpha testing
End user test the system in operational setting to see if it's useful - correct answer User Acceptance
End user tests the system without help from developers; using actual data - correct answer Beta testing
SDLC - correct answer Software Development Life Cycle
SDLC aka - correct answer Staircase or most referred to as waterfall
Preliminary Investigation Step # - correct answer Step 1 in SDLC
Analysis Step # - correct answer Step 2 in SDLC
Logical Design Step # - correct answer Step 3 in SDLC
Physical Design Step # - correct answer Step 4 in SDLC
Implementation Step # - correct answer Step 5 in SDLC
Maintenance Step # - correct answer Step 6 in SDLC
SDLC - Preliminary Investigation - correct answer Problem or opportunity that a new system could be developed to address. During this first step, the team assesses the feasibility of the proposed project and selects a development methodology
SDLC - Analysis - correct answer Determine user requirements for new system and develop logical system models (i.e., graphic displays that demonstrate the relationships between resources, activities, and outputs and outcomes)
SDLC - Logical Design - correct answer Models developed during the second step are revised to ensure that the new system will meet the user requirements identified in the first step
SDLC - Physical Design - correct answer Logical models converted but are still abstractions of the system that will be built later, but they are now more complete and may include network maps and descriptions of servers and other devices to be used in the system
SDLC - Implementation - correct answer Programmers begin converting the models from the previous steps into the actual system, for instance, by developing databases and other software programs that will be needed. This step also includes installing hardware, testing the system, and training the end users
SDLC - Maintenance - correct answer Modifications or corrections to the system are made
Three main categories of a database? - correct answer Flat file, relational and hierarchical
Flat file - correct answer One large single table without the relations between tables that a relational format provides
Relational Database - correct answer Multiple tables (relations) with interrelated fields
Hierarchical Databases - correct answer Organizes data using a tree-like or organizational chart type structure (the child can only have one parent)
MVC stands for? - correct answer Model-View-Controller
What is MVC? - correct answer Software development technique used in the implementation of user interfaces which include the model, the view and the controller
Model in MVC - correct answer Software logic, business rules and application data
View in MVC - correct answer User interface (i.e.; colors, fields...ect)
Controller in MVC - correct answer Communication between the user and the model
Which component facilitates communication between the other two components in the MVC architecture model? - correct answer View
Types of system conversion (SDLC) - correct answer Direct, Parallel, Pilot, Phased
Direct Conversion - correct answer The old system is "turned off" and the new system is "turned on" at a specific date and time
Parallel Conversion - correct answer Period of time in which both systems (the old and the new) are operating concurrently
Pilot Conversion - correct answer Starting the conversion with a portion of the end users, for instance in a specific geographic region or a department in an organization
Phased Conversion - correct answer Deploys a subset of the system first, rather than deploying the whole system at once
Which type of system conversion involves starting the conversion with a portion of the end users? - correct answer Pilot
What is the database administrator's role in security? - correct answer To eliminate data redundancy when integrating old with new systems
Administrator - correct answer Someone who is in charge of some portion of the IT infrastructure
System Administrator - correct answer Process of maintaining the operating system of a computer system (including network of computers)
Network Administrator - correct answer Physically laying down cable, making connections, working with hardware (for instance, routers and switches) and configure the individual machines to be able to communicate via the network
Database Administrator - correct answer Design, development, support, installation, maintenance, performance analysis, and troubleshooting
Difference between compiler and interpreter - correct answer Translates an entire program into executable, which can be run at a later time, while other does it incrementally
Which data communication medium is used over very long distances? - correct answer Radio signals since cable is too expensive
Most common form of network connection used today? - correct answer UTP (Un-shielded Twisted [wire] Pair) and fiber optic cables
Coaxial Cable & UTP have in common? - correct answer Transmit information using electromagnetic waves
Fiber Optic - correct answer Transmit information using light pulses
Radio signals - correct answer Sent via radio towers, cell phone towers, and bounced off of satellites in orbit [Show Less]
