2 You are asked to create a database to produce a report of customer details. The report is to list the customer name, account balance, credit limit and other customer details. The report will be also list the customer account rep (one of our sales employees). Our sales reps manage many customers each, but each customer will be managed by only one account rep at any one time.

List the entities, attributes and relationships among entities to be included in the ER model. Identify the cardinality of each relationships and Draw on ER diagram

StayWell also rents out properties on a weekly basis to students attending summer school in the Seattle area. Design a database to meet the following requirements, using the shorthand representation and a diagram of your choice. For each student renter, list his or her number, first name, middle initial, last name, address, city, state, postal code, telephone number, and e-mail address.

The rental period is one or more weeks.

E-R diagrams or DBDL may show database structure. Why do you prefer this method?

When constructing a database, the designer must know what types of relationships exist between records in different data sets, such as one- to-many or many-to-many. Give three examples for each of these relationships.

When creating a database, here are the general steps that I follow: (a) determine the purpose of the reports I want to generate, (b) identify the format of the report, (c) ensure the data needed is available, (d) confirm the data is reliable. In some cases, the report format that I want to use is not available. Thus, I will work with my tech team to create the report. How can someone determine if the data is reliable? How can it be confirmed? Please discuss.

“Supporting a travel agency, TORS maintains tour information and provides reservation facilities for the people who wish to travel on tours via the Internet. The system allows users to view information about the tours available and make a reservation on a tour without asking the employees at the agency. Using the system, a user can cancel an existing reservation that the user made. The system also allows the user to send feedbacks by e-mail to the agency andstores the feedback in the database. Finally, the system allows the employees of the agency to manage customer information and tours such as adding, deleting, and updating information on customers and tours. For security purposes, the employees are required to provide login credentials (ID and password) to access the system.” Draw two system sequence diagrams, one for the success scenario of each use case. (Note : Please give me the sequence diagram for the above question)
