What Is an Information System? Dave Bourgeois and David T. Bourgeois Learning Objectives Upon successful completion of this chapter, you will be able to: Introduction If you are reading this, you are most likely taking a course in information systems, but do you even know what the course is going to cover?
When you tell your friends or your family that you are taking a course in information systems, can you explain what it is about?
For the past several years, I have taught an Introduction to Information Systems course. The first day of class I ask my students to tell me what they think an information system is. The study of information systems goes far beyond understanding some technologies. Defining Information Systems Almost all programs in business require students to take a course in something called information systems.
But what exactly does that term mean? The Components of Information Systems As I stated earlier, I spend the first day of my information systems class discussing exactly what the term means. Many students understand that an information system has something to do with databases or spreadsheets.
Others mention computers and e-commerce. And they are all right, at least in part: The first way I describe information systems to students is to tell them that they are made up of five components: The first three, fitting under the technology category, are generally what most students think of when asked to define information systems.
But the last two, people and process, are really what separate the idea of information systems from more technical fields, such as computer science. In order to fully understand information systems, students must understand how all of these components work together to bring value to an organization.
Technology Technology can be thought of as the application of scientific knowledge for practical purposes. From the invention of the wheel to the harnessing of electricity for artificial lighting, technology is a part of our lives in so many ways that we tend to take it for granted.
Each of these will get its own chapter and a much lengthier discussion, but we will take a moment here to introduce them so we can get a full understanding of what an information system is. Hardware Information systems hardware is the part of an information system you can touch — the physical components of the technology.
Computers, keyboards, disk drives, iPads, and flash drives are all examples of information systems hardware. We will spend some time going over these components and how they all work together in chapter 2.
Software Software is a set of instructions that tells the hardware what to do. Software is not tangible — it cannot be touched. When programmers create software programs, what they are really doing is simply typing out lists of instructions that tell the hardware what to do.
There are several categories of software, with the two main categories being operating-system software, which makes the hardware usable, and application software, which does something useful. Examples of application software are Microsoft Excel and Angry Birds. Software will be explored more thoroughly in chapter 3.
Data The third component is data. You can think of data as a collection of facts. For example, your street address, the city you live in, and your phone number are all pieces of data. Like software, data is also intangible.
By themselves, pieces of data are not really very useful. But aggregated, indexed, and organized together into a database, data can become a powerful tool for businesses. In fact, all of the definitions presented at the beginning of this chapter focused on how information systems manage data.
Organizations collect all kinds of data and use it to make decisions. These decisions can then be analyzed as to their effectiveness and the organization can be improved.
Chapter 4 will focus on data and databases, and their uses in organizations. A Fourth Technology Piece? Besides the components of hardware, software, and data, which have long been considered the core technology of information systems, it has been suggested that one other component should be added: An information system can exist without the ability to communicate — the first personal computers were stand-alone machines that did not access the Internet.Increase your knowledge of essential information systems topics with the learning tools offered in this interesting help and review course.
Our video lessons are short yet still cover all the important information you're learning in class. Information systems are the software and hardware systems that support data-intensive applications.
The journal Information Systems publishes articles concerning the design and implementation of languages, data models, process models, algorithms, software and hardware for information systems. Computer and information systems managers, often called information technology (IT) managers or IT project managers, plan, coordinate, and direct computer-related activities in an organization.
They help determine the information technology goals of an organization and are responsible for On-the-job training: None.
Information & Management serves researchers in the information systems field and managers, professionals, administrators and senior executives of organizations which design, implement and manage Information Systems Applications. The major aims are. Firms have considered various forms of incentives for writing reviews, including the use of extrinsic rewards to attract reviewers.
Building on this literature, we study the implications of monetary incentives on online reviews in the context of a natural. About Laboratory Information Systems Orchard Software is a leader in the laboratory information system industry and offers a variety of LIS solutions.
