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.

	/**
	* Update the entries for a specific marker
	* @param markerId Marker document ID
	* @param entry Entry to be added to the marker
	*/
	updateEntriesForMarker(userKey: string, inmueble: any) {
	return this.angularFirestore
	.collection('users')
	.doc(userKey)
	.collection('inmuebles')
