The first step in designing any database is known as requirement analysis, where you collect information about a scenario/application you would like to build a database for, while the second step, the Conceptual database design, is to convert the collected information into an ER diagram. Think of a scenario/application (e.g., online shopping, car-rental service) that requires a database, then:

1- Provide a short description (3-4 sentences paragraph) of the idea.

2- Develop an ER diagram that captures such an idea with at least five entity sets and at least five relationship sets.

3- Each of your entity sets should be described by at least four attributes.

In class, we will use universities and companies as examples throughout the chapters, so you MUST develop a different example for this question.
