For the data to be useful, it must be complete, correct and relevant. On the other hand, examples of data that would not go into an AIS includes memos, correspondence, presentations and manuals. Before there were computers, AISs were manual, paper-based systems, but today, most companies are using computer software as the basis of the AIS. Quality, reliability and security are key components of effective AIS software.
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.
We will be covering networking in chapter 5. People When thinking about information systems, it is easy to get focused on the technology components and forget that we must look beyond these tools to fully understand how they integrate into an organization.rutadeltambor.com has been an NCCRS member since October The mission of rutadeltambor.com is to make education accessible to everyone, everywhere.

A article in Harvard Business Review referred to information technology as consisting of three basic parts: computational data processing, decision support, and business software.
This time period marked the beginning of IT as an officially defined area of business. Journal of Management and Marketing Research Management information systems and business decision making, Page 2 1.
Introduction Information Systems can be conceptualized in terms of three types of systems. Introduction rutadeltambor.combook,youwillbeintroducedtothe concept of information systems, their use in business, and the larger.
The "classic" view of Information systems found in the textbooks in the s was a pyramid of systems that reflected the hierarchy of the organization, usually transaction processing systems at the bottom of the pyramid, followed by management information systems, decision support systems, and ending with executive information systems .
