In this assignment, you will study databases and differentiate between the various database models and tools available to design databases.

Specify at least two real-life situations where you have seen a database in use and based on your observations, answer the following questions:

How different would each situation be without the database?

What are the components of the database or data storage system that you have seen in use?

Which type of database system is being used in the establishments where you have seen the database? How did you recognize this type of data storage system?

Why do these situations benefit from the use of databases? What are the factors that make it necessary to use databases in these examples?

Pick one of the database models and list at least two situations in which the model can be applied. You can choose to find the model used in the database that you find in your real-life situation and then answer.

Further, research the Internet for features of the tools that can help you create a database design. You can confine your search to:

Erwin

Power Designer

Based on your research, would you recommend any of these tools for database design based on the information available on the Internet? Why or why not? You may discuss other tools in addition to these.
