Using Oracle, using DDL and DML statements. Create tables to fulfill the requirements of the ER diagram attached. Populate the newly created tables with three records of data and write two queries with the following requirements: A query (or queries) that lists all of the records in all of the tables. A query that lists the meals and clients -- you will need to join the tables to do this. The output should list Employee Name, Expense Type, Expense Date, Expense Description, Expense Amount, and Client Name. Please include ERD, .sql files, and screen shots (PrtSc then paste into a .doc file) of the output from running the queries. Put all files in a directory and then zip them up. Send me the .zip file.

Hello and thank you for using JustAnswer. It would be my pleasure to assist you with this.


Did you create this ERD? There are serious design issues with the ERD that make implementing this a significant challenge. Composite keys are being used incorrectly, there are foreign key references that are not permitted in oracle, and the design violates second normal form.


If you created this ERD, then we need to rewrite it into something workable. Please let me know by when you need this completed and if you would like me to create an ERD that will work in Oracle.


Thank you

Yes - I created it. I am learning this so I am in the basic steps of creating ERDs. If you need to rewrite it...its ok. If you can complete it by end of business today would be great. Let me know if you have other questions or concerns. Thanks for your help.

Hello again,

I apologize. However, I will not be able to complete this by EOB today, as I have other obligations this afternoon. I can have it to you be the end of the actual day 11:59PM EDT.

Let me know if that will work.

Sure. Thanks.

Hello again,

While I am away (Doctor's appointment), can you provide me with the original business case upon which you created this ERD? It isn't entirely evident from this ERD.

Thank you
Customer: replied 4 years ago.

J. Smith, Inc. has five employees and generates large amounts of receipts every month and has had difficulty keeping track of company expense receipts. The company issues each employee one credit card. The credit cards can be used for office expenses, meals with clients, and travel expenses. Each time an employee has a meal with a customer it must be tracked to fulfill IRS regulations. The company must keep a record of the date of the meal, cost, and reason for the meal with each person in attendance. Create an ER diagram that captures this scenario using crows foot notation.

Thank you.

I will contact you once this is complete.
Hello again!

Please download the files here:


In the zip file, you will find three SQL files and one word document .The word document contains the new ERD, all of the SQL and all of Screenshots.

The SQL files contain exactly what is stated in the file title. Of course, DDL must be run first, then DML, then you can run the queries (if you chose to run any of them).

All of the requirements have been met and your ERD is now such that you should receive an excellent grade for this.

Let me know if you have any questions. I am here to help.
