Introduction to Integrated Systems 1 Data Data is a raw fact and can take the form of a number or statement such as: – Dates – Measurements – Phone numbers – Book titles 2 Information It is data that have been processed so they are meaningful This requires a process that is used to produce information, including: – Collecting data – Classifying data into categories (books by subjects, students by colleges) – Sorting organized data so that items are placed into a particular order 3  Quality of Information The differences between “Good” and “Bad” information, including: - Timing - Contents - Form of information 4 Timing (just on time) Means information should be available when needed - If the information is provided too early, it may be no longer current when used - If the information is supplied too late, it will be of no use - Also information should cover the correct time period 5  Content The content of information refers to factors such as: - The accuracy of the information, and - The relevance of information to a particular situation and user 6  The Form of Information Refers to aspects (features) such as: - The clarity of the information which should be appropriate (suitable or fitting) to the intended recipient (receiver, user) - The recipient should be able to locate specific items quickly and should be able to understand the information easily - Information should also contain the correct level of detail in order to meet the user’s information needs 7  System A collection of components that work together towards a common goal. The general objective of a system is to receive inputs and transfer these into outputs Every system has a single goal, but when a system contains several sub-systems with sub- goals, all contributing to meeting the overall system goal 8  A System’s Components Data to be used as Input (1) for a Process (2) that creates information as an Output (3) In order to monitor the performance of the system, a feedback (4) mechanism is required Control (5) must be applied to correct any problem that occur and ensure that the system is fulfilling its purpose 9  An Information System An information system is a collection of five interrelated components, including: people, hardware, software, data, and procedures that work together to provide information to a person or an organization Others add communication instead of procedures to carry out input, processing, output, storage, and control actions in order to convert data into information products 10 People People resources include: - Users of an information - Developers of an information system - Staff (IS managers, Information professionals) who help maintain and operate the system and who help in retrieving information 11  Hardware Computer hardware includes the physical parts of a computer, such as the case, central processing unit, monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. 12  Software System software is software designed to provide a platform for other software. Examples of system software include operating systems like macOS, Linux, Android and Microsoft Windows, 13  Data Facts used usually to calculate, analyze, or plan something 14  Procedures Interrelated procedure necessary to achieve a well defined goal. Systems and procedures help your office run smoothly. They facilitate stress relief, make your job easier, and allow someone else to do your job with little to no problem if you're sick, on vacation, or out of the office. 15  Types of Information Systems Can be categorize into two categories: 1. Operational Information System: which concerns of control processing, transactional processing, (such as collecting, organizing, classifying data) and communication (retrieving and borrowing) 2. Management Information System: which concerns of providing support to decision makers (statistics about the use of information) 16 An Integrated Library Automation System It means combining different library services and operate them into a single systems, such services include circulation, periodicals, cataloging, classification and acquisition It also refers to a library system that uses a shared electronic database and has two or more sub-systems that can be used online 17 Continue The integrated system works as a gateway that enables libraries to have access to the internet and other libraries’ online catalogs An IS contains a number of sub-systems, such as circulation, periodicals, cataloging, classification and acquisition 18
