I have been asked to create a graphical representation of our database, I have looked at tools such as, lucidchart. Are there any good tools that I can use to graphically represent the database and it's relationships?
If you're using MySQL then MySQL Workbench will create Entity Relationship Diagrams from a database.
If you're using "Microsoft Office Access, Microsoft SQL Server, and other databases that are compliant with Open Database Connectivity (ODBC)" then Visio Professional will do this. (Note - Visio Standard doesn't do this.)
