Entity Relationship Diagrams (ERDs) are a great way to design a database visually, before you actually start creating your tables. What’s better, is that many ERD software have the ability to export out the diagrams as SQL code to be imported into your database.
In this series, we’ll be using Lucid Chart, a free to learn tool. It runs in the browser, so it can run on any machine with a modern web browser. Don’t have it, please use this sponsored link: https://try.lucid.co/zlnr7a17uth3
How to Set Up Your Workspace to Easily Create ERDs

How to Add Field Level Details to an ERD Entity
In this video we explore how to define information about your fields that will take you from a simple abstract Entity Relationship Diagram ,or ERD, to a functional ERD which includes defining which fiends are keys for the entity as well as different data types you might expect to use. The key types we look at are primary keys, foreign keys, and unique keys. Additionally, we look at numeric, date and datetime, varchar, enum, currency/decimal, and more data types that you might expect to find your fields using. This is all to set up your ERD so you can export out your SQL Create commands as necessary. You can find that in our next video in this series: https://youtu.be/Jiz-Q1WAWo8
How to Export From the ERD to a Database
In this video we explore how you can take your Entity Relationship Diagram, or ERD, from LucidChart, and export out the SQL Create commands to create those entities into a Database Table. We look at what you can do, such as choosing the type of database to export to, as well as what you cannot do, such as export out multiple entities at once. This is a great tool to help you convert your ERD into a database quickly and efficiently. Something that helps when time is money.
