Customer Question

I would like Alex to help me with my homework question please.


Defining data relationships is an important process during the database design.



  • Describe your idea for a database that includes at least four tables. Explain the relationships between the tables.

  • How did you go about identifying the tables and the relationships? What process did you use?

  • Why do you think relationships are important in database design?

  • What are the benefits of defining relationships in your database design?

  • What are some issues of having a database that is not normalized?

  • Why would you consider creating a database that is not normalized?


 


Consider a typical sales invoice that would include the following information. Design a single table to hold all of the information required to store an invoice including this information. Next, apply normalization to reduce this table to third normal form. Prepare a Word document showing the original and final tables. Include a short summary (2–3 paragraphs) of the problems with the original single table design and how normalization improved the design.

Thank you so much and is there a way of just getting your link when I ask another question? Plus I have fallen behind in my database course and I have a group assignment due tonight! What are the chances of getting that done by midnight?

Expert:  Alex replied 9 months ago.
Hi, I'm done for the night but will be back on tomorrow night. I usually am online late evenings nightly.

You can ask me directly at www.justanswer.com/homework/expert-alex

Also, starting tomorrow JustAnswer is offering some additional services that will allow private conversations and emails with your expert!

Alex..hello. What do you think about helping me out with the group project?

Expert:  Alex replied 9 months ago.
Hi. Could you send me the details?

Thanks
Alex
Customer: replied 9 months ago.

Hello Alex, that is pretty much the "details" that I previously posted. Is there something more I should add? I'm not really sure except a out specs although the Prof did say he wanted us to each turn in a rough draft of the whole assignment. Meaning? A detailed portion of each question. Hope that helps. If not, wait until I get more specific details from the Prof.

Expert:  Alex replied 9 months ago.
Ok. Let me find your question.
