    I've worked on thousands of databases, yet I watched both parts with laser focus. The quality of this content is simply incredible. I wish I had access to that when I started out.

      I'm starting out now, technically I'm making my second database, but my first only needed one table, my next one, it won't be so simple. Love youtube!

    The fact it can convert the diagram to code to create the tables! And to be able to do it in reverse from database to diagram! That is awesome and such a big time saver🙏🏾 thank you 😊

Or should I store the column meanings in a different document in Lucidchart? Or in a different software altogether? Thanks for your insight!

    Is there any example of that csv file structure? I dont want to install DB in order to be able to import structure to Lucid. I have prepared the structures in excel. Why is it not possible just simly CTRL+C in my excel and CTRL+V in the entity from ERD in lucid... Can I do that? If not why? Is there some detailed guíde how to import structures to ERD in Lucid, because I can not find any...

    I imported an existing SQL Server tables into the ER diagram using TSV export. CSV export is not doing the relationships, so did TSV. Great, it works!
    a) I placed each entity by clicking. Is there a way to add multiple tables at a single shot? (like ctrl select)
    b) I have over 80 tables and once placed very hard to find an entity. Is there a way to search the entity on the canvas/diagram?
    I see shapes pane and by clicking the name, it places one more entity in the canvas, which is not what I am looking for...
    c) Any techniques for senior data modelers? TIA

    question, for the composite key section, why don't we just add "customer_ID" as a foreign key? it can make it easier to identify the order like in the example of having 2 different items being shipped as two different packages? i am just asking to make sure if my idea is valid. trying to learn and get better at databases here.

    • @jeanlaughton1215
      @jeanlaughton1215 22 дня назад

      What happens if you only know customer name.. you need a composite key to bind the two entities.
