Learning Objectives Data Learning is raw, objectives unorganized or collection of facts Keywords Data can be something simple and seemingly random and useless until it is organized. Example: Each student’s test score is one piece of data Information …. Learning Objectives When Learning data is processed, organized, structured or presented in a given context so as objectives to make it useful, it is called information. Keywords Processing Input : Data Output: Information Example: The average score of a class or of the entire school is information that can be derived from the given data. Today’s Learning Topic Objectives Toobjectives Learning introduce Keywords Basic concept of Data & Information?

But structured data represent only 5 to 10% of informatics data. Type andObjectives Learning States of Data 1) objectives Learning Structured Data Keywords 2) Semi Structured Data 3) Unstructured Data It often include text and multimedia content. Example: e-mail messages, word processing documents, videos, photos, audio files, webpages and many other kinds of business documents. Unstructured data represent around 80% of data. Type andObjectives Learning States of Data 1) Structured Data 2) Semi Learning Structured objectives Data Keywords Semi-structured data combines unstructured and structured data because it contains elements of both. Semi structured data is information that doesn’t reside in a relational database but it does have organizational properties that make it easier to analyze. A few part of data (5 to 10%) Example: CSV(Comma-Separated Values), XML (Extensible Markup Language) documents CSV in Excel Learning Objectives A CSV (comma-separated values) file is a text file that has a specific format which allows data to be saved in a table structured format. Example.xlsx Learning objectives Example.csv Keywords Check your excel version in Window: File => Account Check your excel version in Mac: Excel => About Excel CSV in Excel Learning (2007) Objectives Learning objectives Keywords CSV in Excel (2019-2021) Learning objectives Keywords XML in Objectives Learning Excel XML (Extensible Markup Language) (.xml), that is sharable between different programs, is a simple text-based format for representing structured information: documents, Learning objectives data, configuration, books, transactions, invoices, and much more. Keywords It describes only the content of the file using tags or “set of rules” and then saved as an XML file. book.xml book.xlsx XML in Objectives Learning Excel (2007) Learning objectives Keywords XML in Excel (2019-2021) CSV/XML in Previous Ver of Excel 16.31 (Mac) Learning Objectives For XML import For both CSV & XML Data>>Get External Data>>From Other Data = > Get Data => From File => From Text/CSV or From XML Sources>>From XML Data Import.

Keywords Data can be observed but not measured. Observed to the quality of the data such as colors, textures, smell, tastes, etc. 5)Learning Quantitative ObjectivesData Data Learning with numbers. objectives Keywords Data can be measured and observed. Measured to the realistic/practical matters such as ( In a room, how many boys and girls are there?) Today’s Learning Topic Objectives Toobjectives Learning introduce Keywords Basic concept of Data & Information? How does Information become? Type and States of Data What Standards is Information System? What is Information Learning Objectives System? Learning objectives System Information Keywords An organized, Components that work together meaningful and to achieve a goal by accepting useful interpretation input, processing it, and of data. producing output in an organized manner. Information System A system, in which four critical components work together to collect, manage, process, analyze data, that purely depends on information and produces information (to help companies solve problems and make decision). Information Systems Learning Objectives Why should we learn about information systems in business organization? Information objectives Learning systems transform industries Keywords Companies gain advantages with Information System Non-profits achieve mission with Information System Strategies rely on Information System Standards Information Systems Learning Objectives Information systems used by - Sales Learning objectives representatives Keywords - Managers - Financial advisors - Entrepreneur Standards- Medicine - Research Information systems - To help you achieve your career goals - To increase revenues and reduce costs Components of an Information System Learning Objectives The four components are Learning objectives 1) People Keywords 2) Technology 3) Processes 4) Data Components of an Information System Learning Objectives The four components are Learning objectives 1) People Keywords ▪ The design, development, launch, and maintenance of any information system involves teams of people. ▪ Play a number of different roles – visionaries, developers, managers of information systems and also as analysts, liaisons, users, customers, contributors. Components of an Information System Learning Objectives The four components are Learning objectives 1) People Keywords 2) Technology ▪ Information Technology (IT): The hardware, software, and telecommunications that comprise the technology component of information systems: the term is often used more broadly to refer to information systems. Information System Standards People Hardware Software Networks Processes Data Technology Components of an Information System Learning Objectives Business process management (BPM) is The four components are the field that focuses on designing, Learning objectives 1) People Keywords optimizing, and streamlining processes, taking into account the human element. 2) Technology 3) Processes To manage business processes also take ▪ A set of activities designed to achieve a task. into account the overall organizational culture. Eg. Banks, hospitals, military units, and a volunteer organization Components of an Information System Learning Objectives The four components are Learning objectives 1) People Keywords 2) Technology 3) Processes 4) Data ▪ Data or facts that are assembled and analyzed to add meaning and usefulness. Quiz 1) In its simplest form, what represents streams of raw facts with limited usefulness until organized. 2) What is produced/generated as a more meaningful form from converting raw data? 3) What is needed to covert raw data into information? 4) How many types and state of data are there? List them. 5) What are the three characteristics that make information valuable? 6) What is an information system? And list its components. Discussion How do yourself get any data if you needed? Did you make any data observation / measurement in the past? Make at least one quantitative & qualitative data with students! Any Questions? Next Lecture Information Systems and Strategy
