Schema Spy - schemaspy.org

Development Documentation Status Quality Gate Coverage Gitter Docker Pulls

Please support the project by simply putting a Github star. Share this library with friends on Twitter and everywhere else you can.

If you notice a bug or have something not working, please report an issue, we'll try to fix it as soon as possible. More documentation and features expected to be soon. Feel free to contribute.

This is a new code repository for SchemaSpy tool initially created and maintained by John Currier. I personally believe that work on SchemaSpy should be continued, and a lot of still existing issues should be resolved. Last released version of the SchemaSpy was in 2010, and I have a plan to change this.

I would like to say thank you to John Currier for the invention of this database entity-relationship (ER) diagram generator.

My plan is to release new SchemaSpy version and concentrate on refactoring and improving it.

In new SchemaSpy 6.0 version you will find:

  1. Absolutely new amazing look and feel generated content

  2. You can very easily change SchemaSpy theme because all of the logic was moved outside the Java code

  3. Speed of database generation improved a little

  4. Generation of the html pages was changed from plain concatenated text in Java code to Moustache engine

  5. In database comments you can use Markdown language what should improve user experience from reading your database documentation

  6. You can also easily create in database comments links to the tables and columns

More detail will came in next days plus I have plan to start working on all not resolved issues.

FAQ

General

Schema or Catalog name can't be null

This means that Schema or Catalog information could not be extracted from connection.
I this case you need to add options -s [schemaName] or -cat [catalogName]
In most cases for catalog you can use -cat %
In mysql you can use same as -db

OSX

Graphviz

There have been lots of issue with graphviz and OSX
So install using brew brew install graphviz --with-librsvg --with-pango
If you already have graphviz installed you need to uninstall and then install

brew uninstall graphviz
brew install graphviz --with-pango --with-librsvg

Depending on OSX version
Older than High Sierra, add -renderer :quartz to the commandline
High Sierra or newer, add -renderer :cairo to the commandline
