Notes of Information systems

•What is an information system?
•A set of interrelated components that collect (or retrieve), process, store, and distribute information to support decision making and control in an organization
Management information system (MIS)
•An MIS provides managers with information and support for effective decision making, and provides feedback on daily operations
•Output, or reports, are usually generated through accumulation of transaction processing data

•Each MIS is an integrated collection of subsystems, which are typically organized along functional lines within an organization
Information
Systems in the
 Enterprise
Objectives
•Evaluate the role played by the major types of systems in a business and their relationship to each other

•Describe the information systems supporting the major business functions: sales and marketing, manufacturing and production, finance and accounting, and human resources

Different kinds of IS
1.Operational-level systems: support operational managers, keeping track of the elementary activities and transactions
●
2.Management-level systems: serve the monitoring, controlling, decision-making, and administrative activities
●
3.Strategic-level systems: help senior management tackle and address strategic issues


Major types of IS

•Transaction Processing Systems (TPS)
•
•Management Information Systems (MIS)
•
•Decision-Support Systems (DSS)
•
•Executive Support Systems (ESS)

What is System ¨ A system is a set of components which are related by some form of interaction and which act together to achieve some objective or purpose n Components are the individual parts or elements that collectively make up the system n Relationships are the cause-effect dependencies between components n Objective is the desired state or outcome which the system is attempting to achieve What is Simulation ¨ A simulation of a system is the operation of a model of the system, as an imitation of the real system ¨ A tool to evaluate the performance of a system, existing or proposed, under different configurations of interest and over a long period of time n e.g. a simulation of an industrial process to learn about its behavior under different operating conditions in order to improve the process n Reasons for Simulation ¨ Experiments on real systems are too expensive, too dangerous, or the system to be investigated does not yet exist n e.g. Investigating...

UNIT 4 Editors and Debugging Systems This Chapter gives you…  Text editors  Interactive Debugging Systems 4.0 Introduction An Interactive text editor has become an important part of almost any computing environment. Text editor acts as a primary interface to the computer for all type of “knowledge workers” as they compose, organize, study, and manipulate computer-based information. An interactive debugging system provides programmers with facilities that aid in testing and debugging of programs. Many such systems are available during these days. Our discussion is broad in scope, giving the overview of interactive debugging systems – not specific to any particular existing system. 4.1 Text Editors An Interactive text editor has become an important part of almost any computing environment. Text editor acts as a primary interface to the computer for all type of “knowledge workers” as they compose, organize, study, and manipulate computer-based information. A text edi...

MIS is a neces ity of al the organizations. The init al concept of MIS was to proces data from the organization and present it in the for of reports at regular intervals. The system was largely capable of handling the data from col ection to proces ing. It was more impersonal, requiring each individual to pick and cho se the proces ed data and use it for his requirements. This concept was further modified when a distinction was made betwe n data and information. The information is a product of an analysis of data. This concept is similar to a raw material and the finished product. What are ne ded are information and not a mas of data. However, the data can be analyzed in a number of ways, producing dif erent shades and specifications of the information as a product. It was, therefore, demanded ...
