© 2010, Laureate Higher Education Group, Inc. 1 This is the Week 3 Podcast for the course, “Information Technology Infrastructure.“ The topic for this week is Data and Data Management. The purpose of an information system is to store, retrieve, and process information. Computer hardware and software are of little use to an organization without data to process. One of the most powerful features of IT is its ability to structure and organize data so that all parts of the organization can have consistent content and representation. You will see that a database management system (DBMS) can enforce data integrity rules and manage relationships among different data elements. Because the DBMS mediates between the user and the stored data, it can restrict who can see and change any piece of data, arbitrate among conflicting uses, and keep an audit trail of data access. You will learn about data modeling, which represents structured data in a diagram format, and data mining, which can discover hidden patterns in the organization’s data. By the end of this week, you will be able to: Explain how database management software helps business professionals and supports the operations and management of a business Provide examples of relational databases and columnar databases (data warehousing) [Week 3 > Resources] Let’s take a look at the resources you’ll be using this week.
