After 10 minutes - Submit the report of your group. Activity 1 Q & A : Q & A What Is : What Is Information System? Chapter 1 : Chapter 1 An Introduction to Information Systems Learning Objectives : Distinguish data from information Describe the characteristics used to evaluate the quality of data Identify 4 basic types of models & explain how they’re used Name the components of an information system Learning Objectives Learning Objectives : Describe several system characteristics Identify the basic types of business information systems, their users, their benefits, and their uses. Discuss why its important to understand & study information systems Identify the major steps of the systems development process & state the goal of each Learning Objectives Information Concepts : Information Concepts Information System : A set of interrelated components that collect, manipulate & disseminate data & information & provide feedback to meet an objective. Examples: ATMs; airline reservation systems; course reservation systems Interact daily with IS – Personally & Professionally Information System Data vs. Information : Data: raw facts Information: collection of facts organized in such a way that they have value beyond the facts themselves Knowledge : information in action Input(data) – Process – Output(information) Data vs. Information Figure 1.1 : Figure 1.1 Little value Redefine relationship Adding new /different data Create new value Types of Data : Types of Data Process of Transforming Data into Information : Process of Transforming Data into Information Characteristics of Valuable Information : Table 1.2 Characteristics of Valuable Information System and Modeling Concepts : System and Modeling Concepts Model – abstraction that us used to represent reality Fig 1.3 : Fig 1.3 Activity 2 : Explain any existing system and identify the following: Input Process Feedback Output. You may discuss with your group. After 10 minutes present your finding Activity 2 System Concepts Table 1.3 : System Concepts Table 1.3 **** System Performance : Efficiency: compare between output/input Effectiveness: extent to which system attains its goals Performance standard: specific objective of a system System Performance **** Fig 1.5 : Fig 1.5 **** Fig 1.6 : Arithmetic Fig 1.6 4 TYPES OF MODEL Word, Spoken, written Tangible Graphic What Is An Information System? : What Is An Information System? The Component of an IS : The Component of an IS Computer-Based Information Systems : Computer-Based Information Systems Fig 1.8 : Fig 1.8 Activity 3 : Identify the component for the following CBIS: Hardware Software Telecommunication People Database Procedure Activity 3 Business Information Systems : E-COMMERCE (EC) TRANSACTION PROCESSING SYSTEM(TPS) ENTERPRISE RESOURSE PLANNING (ERP) MANAGEMENT INFORMATION SYSTEM (MIS) DECISION SUPPORT SYSTEM (DSS) SPECIAL PURPOSE OF IS: AI, ROBOTIC, GIS,VIRTUAL REALITY Business Information Systems E-Commerce : Business-to-business (B2B) Business-to-consumer (B2C) Business-to-government (B2G) Government-to-consumer (G2C) E-Commerce involves business transactions executed electronically between parties. Parties can be companies, companies and consumers, companies and public sector organizations, or individuals and the public sector. Eg: shopping online, online banking, online publishing,online auction, etc. E-Commerce Fig 1.10 : Fig 1.10 Fig 1.11 : Fig 1.11 TRANSACATION PROCESSING SYSTEM Transaction Processing Systems : Process business exchanges Maintain records about the exchanges Handle routine, yet critical, tasks Perform simple calculations Transaction Processing Systems Enterprise Resource Planning (ERP) : Integrated programs that can manage a company’s entire set of business operations Often coordinate planning, inventory control, production and ordering Enterprise Resource Planning (ERP) Management Information Systems (MIS) : Routine information for routine decisions Operational efficiency Use transaction data as main input Databases integrate MIS in different functional areas The main input to an MIS is data collected and stored by transaction processing systems. An MIS further processes transaction data to produce information useful for specific purposes. Management Information Systems (MIS) MIS Outputs : Scheduled reports – An example might be a weekly sales report that a store manager gets each Monday showing total weekly sales for each department compared to sales this week last year or planned sales. Demand reports - provide specific information upon request. if the store manager wanted to know how weekly sales were going on Friday, and not wait until the scheduled report arrives on Monday, she could request the same report using figures for the part of the week already elapsed. Exception reports - produced to describe unusual circumstances. For example, the store manager might receive a report for the week if any department’s sales were more than 10% below planned sales. MIS Outputs Decision Support Systems (DSS) : Interactive support for non-routine decisions or problems End-users are more involved in creating a DSS than an MIS Eg: company investment Decision Support Systems (DSS) Special Purpose Information Systems : Artificial intelligence (AI) systems (eg: ES,robotics) Virtual reality systems (examples) –3D world create by computer. Geographic Information Systems (GIS) (examples) AI is a broad field of research that focuses on developing hardware and software technologies with human characteristics, such as vision, reasoning, learning and natural language processing. Virtual reality systems include 3-dimensional simulation software, where often the user is immersed in a simulated environment using special hardware (such as gloves, data suits, or head mounted displays). Sample applications include flight simulators, interior design, or surgical training using a virtual patient. Geographic Information Systems include digital mapping technology used to store and manipulate data relative to locations on the earth. An example is a marketing GIS database. Don’t confuse GIS with GPS – the latter, global positioning systems, are satellite-based systems allowing accurate location determination. Special Purpose Information Systems Information Systems Development : Investigation Analysis Design Implementation Testing & Maintenance Information Systems Development Activity 4 : Choose one system in your working place. Name the system and identify the following: Input Process Output Feedback Activity 4 Why Study Information System : Ease the managing task Guide for problem solving & decision making Advance in carrier. Realise opportunities and meet personal and company goals. In Business: used in all functional areas. CBIS important for type of job. Why Study Information System Case Study : Refer Module : Discuss in group the case study “ Grande Pasta”, . Answer all questions and present your group answer. Case Study : Refer Module
