Final summary of research findings

¶ … Systems Concepts:

System concepts are used to observe the formation of the world around us and it is important to discover these concepts. Information systems are created in order to give information that helps management in making more competent and efficient use of these economic resources that are records to the complete organizational system. From a systems view of point, all records are seen as input to, or output from some other system that is considered as an external entity. The present computer hardware and software, data, and humans taking up the processes to run the computer and work on the data are the vital parts of all business information systems used by the current business organizations. Systems concepts are helpful in accepting and examining the way things work: both theoretical and tangible. In using the systems approach in scheming business information systems the following steps are used: we first make out the business objectives and preferred results; Next we find out what are required to attain these results; lastly we find out the procedures and data which are required to get these outputs. The aptitude to explain all systems by their inputs (I), processes (P) and outputs (O) is known as the I-P-O model. (Systems Concepts: An Introduction)

Operating Systems and Programs:

The earlier computers did not have operating systems. A human hand was required to manually load and run the programs. When programs were created to pack and run other programs, it was likely to get their name from the human job they substituted. The operating system makes sure that other applications are capable of using the memory, input and output devices and have approach to the file system. When multiple applications are functioning, the operating systems plan such that all procedures have enough processor time and do not hinder with each other. On the whole, the operating system is the first layer of software laden into computer memory when it commences. All the other software's, which get loaded, relies on this software to offer them with numerous common core services. The common services are: disk access, memory management, task scheduling and user interface. As the OS provides these basic common services, it need not be reinstalled over and over again in other software that we use. The portion of code that does these core services is called the kernel of the operating system. (Operating System: Wikipedia, the free encyclopedia)

Hence the operating system is the most vital program that functions on a computer. Every computer must have an operating system to run other programs. Operating system does basic jobs like distinguishing input from the keyboard, sending results to the display screen, having track of files and directories on the disk, and managing peripheral devices like disk drives and printers. The operating system is like a traffic cop, it ensures that the programs and the users using at the same time do not meddle with each other. The operating system is responsible for making sure that illegal users do not handle the system. (Operating System: Webopedia)

Information Systems Stored Data:

Data and its storage are regarded as the heart of any information system. Data has to be fresh, precise, easy to get in the necessary form and obtainable to one or maybe to many users at the same time. A data gets its importance when it is given in a form, which assists the numerous operational, financial, managerial, decision-makings, administrative and clerical activities within an organization. To meet these goals data must be stored effectively, to evade long access times and with least replication to evade longer update times and the likelihood of discrepancy and imprecision. The data of an organization is in the form of a theoretical representation of objects and events, which arise within the organization's environment. For instance in an airline company these objects may be Aircraft, Passengers and Airports, and even have events like Flights and the issue of tickets. Data can be stored in individual files belonging to separate information systems or it can be stored in a database that can be used as a resource for all departments.

Networking Concepts and the Internet:

The term network has been defined as a set of computers and connected devices that are linked by communication facilities. Thus a network can be two computers connected by a cable or thousands of computers connected by high-speed data communication links that is spread all over the world. Network gives us two basic advantages: the facility to communicate and the facility to share. A network helps in communication between users in better ways than other media. E-mail, the most well-known form of network communication, offers inexpensive, printable communication with the facility of sending, reply, storage, recovery, and addition. Network supports collaboration with its capacity to share. This is the main charm of popular software called groupware that is created in such a way to allow many users to have electronic meetings and work alongside on projects. (Basic Networking Concepts)

Internet is a network of computer networks, upon which anybody who has permission to a host computer can circulate their own documents. World Wide Web is one such network, which permits Internet publishers to connect to other documents on the network. The Internet facilitates communication of a range of file types, including non-written multimedia. There are many types of Internet sites created by different people or organizations for different purposes. (the Basics: The Internet)

Information Systems and Decision Making:

Business executives, when taking strategic decisions use many types of management knowledge, requiring and dealing with a broad range of information within a short period of time. These resolutions are taken within strategic business procedures, which change from one case of the procedure to the other. For instance, when a strategic decision is made for involvement into new markets, business executives will be given documents of case models that have the resemblance of facts used in earlier decisions. Each case study will have a set of essential software parts, which are organized to give the information required to support the decisions in that specific intercession. These case models can be modified to the specific needs of the present business intervention process getting direct data from the business executives. Alterations in the case study will be interpreted into changes in the original pattern, thus modifying the information system to support the new business process.
