• Unit 1: Introduction to Modern Database Systems

    Different databases serve different purposes; each one is dependent upon both deployment environment and different types of user interactions. In this unit, we will ask a number of questions pertaining to databases: What are some database environments and user types? How can the database management system ensure control over data integrity, avoid data redundancy, and secure data, while at the same allowing interactions with different user types? In answering these questions, we will identify and determine the characteristics of databases, their many deployment environments, and the different categories of users that interact with them.

    Completing this unit should take you approximately 5 hours.
