  • Ralph Webster South Africa Having established what the system needs to produce to meet its goals, the next area of interest is establishing what data needs to be obtained to produce that output. The design of the input is vital to the successful creation of a computer system. Put simply, the input must be collected from the various sources with a minimal amount of errors, and with the greatest possible speed. A common term used to describe data entry is GIGO - garbage in, garbage out. This expression highlights the importance of input design to the quality of the program produced. The final output will only be as accurate as the data put into the system - and the quality of that data will be partly determined by the quality of the design of the collection methods. There are a number of techniques that a good programmer will use to ensure that the data they collect is of the best quality possible. They will limit the opportunities for the user to enter the wrong data, and will ensure the user does not have to enter data twice. When designing input, the programmer should: Identify duplicate data - Efficient program design requires that the program only collect and store each data element once. Programmers should analyse the data requirements and identify where data is used more than once and ensure it is collected just once. It is important to do this - while it may be easier to collect data more than once, rather than create highly complex data structures, this approach compromises the integrity of the information produced, as it allows for more input errors and the creation of conflicting outputs. Identify methods of reducing input errors - When collecting data, the programmer should make use of as many of the features available to ensure that the data being collected is as free from errors as possible. This can be achieved through the use of features like drop down boxes, radio buttons, check boxes etc. that limit the user to selecting from pre-defined "correct" options. By carefully constructing input screens, it is possible to limit the number of areas the users can enter invalid data. Identify data validation checks - While it is possible to limit the users choices to pre-defined choices, it may not always be possible or practical to do so. An example would be postcodes. While all postcodes are pre-defined, there are so many of them it would not be possible to list them all on a screen, so another method must be employed to make sure the data is accurate. Writing code to check the data is accurate can do this. For example, the postcodes could be checked to see if they fall within the expected range for the state given. While this relies on the user to input correct data, it does reduce the amount of incorrect data the system collects. Input screen/method design - Thought needs to be given to the actual design of the input collection screens or methods. Care needs to be taken to ensure the screens that collect the data are arranged in an attractive and logical manner. If data is to be entered from a form, then the data collection screens should follow the general format of those screens to make data entry easier, and therefore less prone to errors.

  • Jones Hanungu Munang'andu Zambia Support of knowledge work A large proportion of work in an information society involves manipulating abstract information and knowledge, rather than directly processing, manufacturing, or delivering tangible materials. Such work is called knowledge work. Three general categories of information systems support such knowledge work: professional support systems, office information systems, and knowledge management systems. Professional support systems Professional support systems offer the facilities needed to perform tasks specific to a given profession. For example, automotive engineers use computer-aided engineering (CAE) software together with “virtual reality” systems to design and test new models for fuel efficency, handling, and passenger protection before producing prototypes, and later they use CAE in the design and analysis of physical tests. Biochemists use special three-dimensional modeling software to visualize the molecular structure and probable effect of new drugs before investing in lengthy clinical tests. Investment bankers often employ financial software to calculate the expected rewards and potential risks of various investment strategies. Indeed, specialized support systems are now available for most professions. Office information systems The main objectives of office information systems are to facilitate communication and collaboration between the members of an organization and to facilitate them between organizations. Placing an organization's documents and messages in an electronic format—which can be classified, indexed, and stored for easy retrieval—enables individuals to access information on demand. One type of office information system, known as a workflow system, is used to route relevant documents automatically to all appropriate individuals for their contribution. Other types of office information systems handle digital messages in the form of electronic mail, facsimile, and voice mail. Another category of office information systems allows different individuals to work simultaneously on a shared project by using networked computers. Known as groupware, such systems accomplish this by continually sending updated documents—such as business proposals, new designs, or progress reports—to each collaborator's computer. These individuals and their computers need not be located in the same office or even the same building. Groupware is usually deployed over an intranet, a private network that is closed to the general public, and is often accessed by using software originally developed for the Internet. Knowledge management systems Knowledge management systems provide a means to assemble and act on the knowledge accumulated throughout an organization. Such knowledge may include the texts and images contained in patents, design methods, best practices, competitor intelligence, and similar sources. Organizational knowledge is often tacit, rather than explicit, so these systems must also direct users to members of the organization with special expertise. Access to an organization's knowledge is often provided via an intranet equipped with specialized search software. The next section, Management support, describes how information systems are used to assemble reports and reach executive decisions.
