WGU C182 (Questions + Answers) Solved

Activity performed by an organization to ensure that critical business functions will be available to customers, suppliers, regulators, and other entities that must have access to those functions. - Business Continuity An understanding of why something is or was. Can only come by having knowledge and experience. - Wisdom (DIKW) Can include inventory, employee information, and financial data from multiple databases gathered from a variety of sources. - Data warehouse Collection of data and information used to support management of an organization. - Information System Company can prepare large amounts of data in advance, then process information in one batch when computer system is not busy (e.g. non-work hours). - Batch processing Computers built with transistors and used magnetic core memory. Computers began using boolean operators. Mainframe computers (used by large organizations for critical applications, bulk data processing, etc) first developed. - Second generation of computers Computers built with vacuum tubes. Created by both sides to gain an advantage in WWII. Computers required programming in machine language. ENAC (first general-use computer) is developed. Built to more easily calculate trajectory of missiles. - First generation of computers Data are processed through a suite of analysis software tools. - Online Analytical Processing (OLAP)Data being used must apply directly to the decision being made (e.g. if information is needed about a customer's purchase history, in order to better serve the customer's needs, it is relevant to collect data on prior business transactions with the specific customer). - Relevant (Characteristics of quality data) Data captured from business transactions and stored in databases which can then be processed via queries to support decision making. - Online Transaction Processing (OLTP) Data must be captured as close to the point of activity as possible (e.g. Making sure customer addresses are correct before sending out coupons) - Accurate (Characteristics of quality data) Data must be efficient and must be provided in a timely manner so that companies can utilize it in their business (e.g. If a company set their budget for the new fiscal year, they would need access to financial data from most recent years). - Timely (Characteristics of quality data) Data must not have any error or lapses (e.g. Client gives apt number in address so shipping company knows exactly where to go) - Thorough (Characteristics of quality data) Data processed in real time. - Online Data Processing (OLDP) Data should reflect stable and consistent data collection processes across collection points and over time, whether using manual or computer-based systems, or a combination (e.g. All employees track sales with sales tax). - Reliable (Characteristics of quality data) Data transformed in to something useful (e.g. list of numbers processed through statistical analysis). - Information (DIKW) Data, information, knowledge, wisdom. - What are the parts of the DIKW? Development technique used in the implementation of user interfaces (e.g. Marketing manager wants to see how many units of a product is on-hand to justify a new marketing campaign you would request this information via the controller. The user wouldn't form the actual query, but would input the type of datarequested, perhaps selecting from a drop down menu the item number and type of report requested. The controller would send this data to the model. The model would then develop a query based on the information sent to it from the controller and the result of the query would be presented in the selected view (report) back to the user). Includes the model, the controller, and the view. - MVC model and its parts E. octal and hexidecimal - Which of the following pairs of numbering systems use the least number of digits in machine code? A. binary and hexidecimal B. decimal and binary C. octal and binary D. decimal and hexidecimal E. octal and hexidecimal Fifth step. 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. - Implementation (SDLC) First step. Organization discovers a 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. - Preliminary investigation (SDLC) First step. Problem definition, resource allocation, and risk assessment. - Initiation (Project management) Fourth step. Teams often need to write a final report detailing the processes and outcomes of the project. - Closing (Project management) Fourth step. The logical models are converted into physical models. These physical models 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. - Physical design (SDLC)Gives developers a framework they can build upon to develop to customize applications. - PaaS Helps to capture the knowledge contained in various information systems within the company for making strategic decisions. - Business intelligence Initiation - Planning - Executing & Controlling - Closing - Project management steps Input directly received by human or computer (e.g. taste or smell for human and input for a computer). - Data (DIKW) Interface for the user, often personalized for that given user. Provides access to the kernel. - She
