Slide 4: However, as new information technologies have been developed, new categories of information systems have emerged, some of which no longer fit easily into the original pyramid model. Some examples of such systems are: Data warehouses Enterprise resource planning Enterprise systems Expert systems Global information system Office Automation Slide 5: A Transaction Processing System (TPS) is a type of information system that collects, stores, modifies and retrieves the data transactions of an enterprise. Transaction processing systems (TPS) automate the handling of data about business activities or transactions. Data about each transaction are captured, transactions are verified and accepted or rejected and validated transactions are stored for later aggregation. Slide 6: The goal of TPS development is to improve transaction processing by speeding it up, using fewer people, improving efficiency and accuracy, integrating it with other organizational information systems or providing information not previously available. Example : Airline Reservation System Slide 7: The Airline Reservations System (ARS) was one of the earliest changes to improve efficiency. ARS evolved into the Computer Reservations System (CRS). A Computer Reservation System is used for the reservations of a particular airline and interfaces with a Global Distribution System (GDS) which supports travel agencies and other distribution channels in making reservations for most major airlines in a single system. Slide 8: Airline Reservations Systems contain airline schedules, fare tariffs, passenger reservations and ticket records. An airline's direct distribution works within their own reservation system, as well as pushing out information to the GDS. A second type of direct distribution channel are consumers who use the internet or mobile applications to make their own reservations. Travel agencies and other indirect distribution channels access the same GDS as those accessed by the airlines' reservation systems Slide 9: Management information systems are those systems that allow managers to make decisions for the successful operation of businesses. Management information systems consist of computer resources, people, and procedures used in the modern business enterprise. The term MIS stands for management information systems. MIS also refers to the organization that develops and maintains most or all of the computer systems in the enterprise so that managers can make decisions. Slide 10: The goal of the MIS organization is to deliver information systems to the various levels of corporate managers. MIS professionals create and support the computer system throughout the company. Trained and educated to work with corporate computer systems, these professionals are responsible in some way for nearly all of the computers, from the largest mainframe to the desktop and portable PCs. Slide 12: An Executive Information System (EIS) is a type of management information system intended to facilitate and support the information and decision-making needs of senior executives by providing easy access to both internal and external information relevant to meeting the strategic goals of the organization. EIS help top-level executives to analyze, compare, and highlight trends in important variables so that they can monitor performance and identify opportunities and problems. Slide 13: Traditionally, executive information systems were developed as mainframe computer-based programs. The purpose was to package a company’s data and to provide sales performance or market research statistics for decision makers, such as financial officers, marketing directors, and chief executive officers. Slide 14: Today, the application of EIS is not only in typical corporate hierarchies, but also at personal computers on a local area network. EIS now cross computer hardware platforms and integrate information stored on mainframes, personal computer systems, and minicomputers. Slide 15: Data warehouse is a repository of an organization's electronically stored data. Data warehouses are designed to facilitate reporting and analysis[1]. A data warehouse houses a standardized, consistent, clean and integrated form of data sourced from various operational systems in use in the organization, structured in a way to specifically address the reporting and analytic requirements. Slide 16: This definition of the data warehouse focuses on data storage. However, the means to retrieve and analyze data, to extract, transform and load data, and to manage the data dictionary are also considered essential components of a data warehousing system. An expanded definition for data warehousing includes business intelligence tools, tools to extract, transform, and load data into the repository, and tools to manage and retrieve metadata(deta about data, where it is located, how it is associated, ownerships etc.). Slide 17: Example : Bank of America creates a database that consolidated 35 million records processed by separate computers handling checking, saving, and other routine transaction. The consolidated database has 800 billion characters of data. Every day about 100,000 customers call the bank to check a balance, challenge a charge on credit card, or ask about interest rates. Slide 18: Enterprise systems (ES) are large-scale, integrated application-software packages that use the computational, data storage, and data transmission power of modern information technology (IT) to support process, information flows, reporting, and data analytics within and between complex organizations. In short, ES are packaged enterprise application software (PEAS) systems, where all three adjectives, "packaged", "enterprise", and "application", in combination, restrict the set of things that can be called ES. Slide 19: Enterprise system including Enterprise resource planning (ERP), Customer Relationship Management (CRM), Supply Chain Management (SCM). ES is a special class of enterprise application software, which is use to solve an enterprise problem. Enterprise application software is application software that performs business functions such as accounting, production scheduling, customer information management, bank account maintenance, etc. It is frequently hosted on servers. Slide 21: A global information system (GLIS) is an information system which is developed and / or used in a global context. For example, The global information infrastructure (GII), which is based on internetworking technology and the world-wide web is currently demonstrating that global information systems will benefit problems that require a synthesis of information from diverse sources if end-users have the ability to tie the information together in a meaningful way. Slide 22: With the progress in global inter-connectivity, we now need to deal with more heterogeneous information consisting not only of a broader variety of digital data, but also operations , such as simulation models, which create new data and information. Slide 23: Example : SAP (System, Applications and Products) By using SAP solutions, companies of all sizes – including small businesses and midsize companies – can reduce costs, optimize performance . SAP creates a common centralized database for all the applications running in an organization. Slide 24: The application has been assembled in such a versatile way that it handles all the functional department within an organisation. Today major companies including Microsoft and IBM are using SAP's Products to run their own businesses. Slide 25: Office automation refers to the varied computer machinery and software used to digitally create, collect, store, manipulate, and relay office information needed for accomplishing basic tasks and goals. Raw data storage, electronic transfer, and the management of electronic business information comprise the basic activities of an office automation system. Office automation helps in optimizing or automating existing office procedures. Slide 26: The backbone of office automation is a LAN, which allows users to transmit data, mail and even voice across the network. All office functions, including dictation, typing, filing, copying, fax, Telex, microfilm and records management, telephone and telephone switchboard operations, fall into this category.
