DIKW HierarchyDefines the transition of data to information from knowledge to wisdom. (Data Information Knowledge Wisdom) Data in DIKWThe input directly received by the user (or computer). It is generally not usable until it has been converted into a relevant form.Information in DIKWHaving been inferred from data; one or more processes have been applied to the data to transform it into a more useful form.Knowledge in DIKWInformation that has been put to use; information placed into a context. Refined information such that the user of the knowledge is able to call forth only relevant portions of information when needed. KNOWING THR RIGHT THING TO DO Wisdom in DIKWProvides a social setting to knowledge; an understanding of the "why". Can only come by having both knowledge and experience.Information SystemsA collection of data and information used to support the management of an organization. Also refers to the technical components and human resources that enable the assembly, storage, and processing of data and the delivery of information. This has existed for a lot longer than computers.Characteristics of Quality DataRelevance - the data being used must apply directly to the decision being made Timely - data must be efficient and must be provided in a timely manner Thorough - the data must be complete Accurate - data should be captured only once, where possible and should be captured as close to the point of activity as possible.Reliable - data should reflect stable and consistent data collection processes across collections points and over time Structured datais coded in a way that makes it easy to convert into a form usable for analysis.Examples of structured datacontact information such as first name, last name, email address, and phone number. In addition, quantitative fields like date of birth, date of transaction, and the amount received or amount due are forms of structured data.Unstructured datarefers to data that is more complex and possibly stored in a format that is not easily decoded.Examples of unstructured datainclude data stored in text or video format, comments on a web page, text messages, and videos of presentations or conferences.To begin analyzing business processesa business must first collect data from multiple platforms and portals.

Data in businesses comes from various activities like sales and marketing, finance, customer service, and relationship management.Companies store data in multiple systems likecustomer relationship management (CRM) system and sales records, finance, enterprise resource planning (ERP), and customer applications. each has data on every customer Data Hygienerefers to the processes of ensuring the cleanliness of data (i.e., that the data is relatively error-free) Data scrubbingthe process of amending or removing data in a database that is incorrect, incomplete, improperly formatted, or duplicated.Quality datadefined as data that is precise, valid, reliable, timely, and complete.Good data enables businesses to do the following: *Analyze the current financial state of the organization in terms of net profits, revenues, cash flow, assets, and liabilities *Increase revenues through better targeting of products and increased customer satisfaction *Examine existing production processes to take corrective action, improve efficiency, and lower costs *Develop new, automated processes that integrate harmoniously into existing workflows and reduce demands on labor *Gather competitive information on product and pricing decisions to stay ahead of competitors *Make evidence-based decisions that utilize verifiable data to maximize profits and efficiency *Understand business value by exploiting rapid changes in information and generating insights from diverse data sources to widen the competitive differentiation gap

Types of bad data*Duplicate data: Two or more identical records

*Conflicting data: The same records with differing attributes

*Incomplete data: Missing attributes

*Invalid data: Attributes not conforming to standardization

*Unsynchronized data: Data not appropriately shared between two systems

three general steps for transforming institutional

knowledge into implementable data solutions:

capturing, analyzing, and using.IPOThe input-process-output

• main functions of a computerInput, processing, Output, Storage

InputRaw data is entered by the user.Processingactoins computer takes to execute commands. Raw data is organized or structured for usefulness.OutputInformation is given out so users can see results. results provided by the computer after processing

StorageProcessed information is stored for permanent record.Computer SystemA collection of components that work together to meet the needs of the user; typically categorized as either hardware, software, networks, or users.The most important element of a computer system is? its users, sometimes called liveware HardwarePhysical components of a computer system which include the system unit and its components and peripheral devices; tangible aspects of the computer.Motherboards, graphics cards, central processing units (CPUs), and power supply Middlewareallows the hardware and software to communicate with each other, enabling data to move between computer system components Softwarea collection of instructions that enable a user to interact with a computer to perform tasks. Internet browsers, text editing tools, and spreadsheets are examples of computer software Types of system softwareWindows, Mac, or Linux Word processing applicationsallow users to type letters, complete assignments, and produce any other written artifact.Spreadsheet applicationsSpreadsheet applications help create charts and complete complex calculations.Email applicationsallow a user to receive and send email communications.Web browsersallow a user to access the content of web pages on various sites.The Motherboardis at the center of what makes a computer work. It houses the CPU and serves as the brain of the system allocating resources, such as power, and communicating with all other components.The CPUprocesses the data from the programs your computer runs.Random-access memory (RAM)occupies the memory slots of the CPU and keeps that data immediately accessible.The hard driveis a storage device that permanently stores data, or temporarily stores data in a paging file system.This paginga built-in mechanism available with most operating systems that permit data to be moved from RAM to the hard drive when the amount of memory in use exceeds the memory available on the computer system.NetworkA collection of computers and resources connected by various media so that they can communicate with each other.
