Watch this lecture and take notes on the security concepts discussed. Note the many different security threats that database management systems may be subjected to and the actions that the database administrator can take to mitigate against some of these threats. In particular, make note of the use of SQL injection attacks as you study SQL later in the course.

Remember, data models not only provide a basis for the design of a computerized database system, they are also very useful for communicating with non-technical business users. Business process owners work with data modelers in order to ensure that the database system being developed will meet the needs of the organization. The data model provides a common point of reference in the development process. As a data professional, you will have to create and structure database tables to support business operations and processes. In conclusion, you learned about various data models, their advantages, and their disadvantages. Now, you can explain data models and apply E-R models using the practical exercises given in this section.
