Plot database table dependecies for a mySQL database (Python)

2010-07-10T08:14:09-07:00

Python recipe 577298 by Noufal Ibrahim (database, dot, graphs, graphviz, mysql).

The following snippet will output a spec suitable for the graphviz dot program. It will go through the database specified and for all the tables that start with any of the names in table_prefixes, it will create a dependency graph. A dependency in this context is when a field of one table has a foreign key reference to another. The edges are labelled with the actual field names.

It can be used like this

python deps.py | dot -Tpng | display

This requires the InnoDB engine (i.e. something that honours foreign keys. MyISAM doesn't do so).

Create module dependency graph (Python)

2010-05-07T11:29:03-07:00

Python recipe 577222 by Noufal Ibrahim (dependecies, graphs, utilities).

The following snippet will dump the module dependencies in a format that can be interpreted by the dot program distributed along with graphviz. You can use it like below to see the dependency graph for the asynchat module for example. (the program is saved as grapher.py)

python grapher.py asynchat | dot -Tpng | display
