Introduction
You have already been introduced to the first two components of information systems: hardware and software. However, those two components by themselves do not make a computer useful. Imagine if you turned on a computer, started the word processor, but could not save a document. Imagine if you opened a music player but there was no music to play. Imagine opening a web browser but there were no web pages. Without data, hardware and software are not very useful! Data is the third component of an information system.
Upon successful completion of this chapter, you will be able to:
- Describe the differences between data, information, and knowledge
- Describe Database, Database Management System, and Database Types
- Characterize the contribution of databases to websites
- Identify relational database elements
- Identify Fields, Records, and Tables
- Recognize that tables can have relationships
- Identify Data Warehouse and Data Mining
- Recognize Meta Data and their use
- Recognize the need for database security
