Your TH-cam videos and website are very helpful to Learn Data Modeling. I came across your videos as I was preparing for my next interview. Also here is a ChatGPT prompt which I wrote to practice interview questions and I hope it's helpful ... "You are an experienced Data Modeler. Tell me some Data Modeler interview question and answers to practice for my upcoming interview. Explain the answers in the format of how did you use it in your last project. Give Questions and Answers to me one by one and ask me if I want more."

Thanks. You need to create unique constraints in data model and implement that data model in database.

[@antonystrainingandsolution8071]

If you would like to the incorporate the changes in the new model, then you can save the existing file "save as" and create a new version. From the new version, you can update it. Else you can work on the existing model.

[@antonystrainingandsolution8071]

Thank you very much.

If I need to work or upgrade an existing ER Model, how do I go about it. Am I going to create a new model or just edit the existing diagram?
