Create Nice-looking Schema Diagrams in PlantUML

PlantUML is a descriptive language to generate a number of types of software diagrams, such as sequence, class, deployment and state diagrams, and many others. PlantUML does not generate very good-looking schema diagrams out of the box, but it supports themes and preprocessed macros. If you use themes and macros, you can not only use a simplified syntax, but also generate beautiful diagrams.

Here is an example of a PlantUML schema diagram, and we will build up the code to generate it.

To start, describe your schemas, tables and columns using this syntax as an example.

	from schedule import Schedule

	class TestLab3ForGrading(TestCase):
	"""Test for Lab 3."""
