Planning - correct answer In what phase of the project does estimation occur? Initiation Phase # - correct answer Phase 1 of 4 in planning Planning Phase # - correct answer Phase 2 of 4 in planning Executing & Controlling Phase # - correct answer Phase 3 of 4 in planning Closing Phase # - correct answer Phase 4 of 4 in planning Initiation key elements - correct answer Problem definition, resource allocation and risk assessment Planning key elements - correct answer Determine objectives and activities, organize the activities, and estimate time and cost required to successfully complete the project Executing & Controlling key elements - correct answer Ensuring that the project is progressing properly and may involve hiring or training personnel, purchase hardware, and developing, testing, and deploying a product or service Closing key elements - correct answer Once all deliverables are met, a project is considered closed. May include a final report detailing the processes strengths and successes and obstacles that were encountered Why is it important to ensure that data support business goals? - correct answer To aid in making strategic decisions Data type needed to order names and numbers in a database - correct answer String data What effect does scope creep have on a project? - correct answer In increases unplanned costs for the project Scope Creep - correct answer Additional features are needed or could be beneficial which can impact the allocation of resources (i.e., time and capital), and put the project at risk 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
