\par }{\insrsid3224836 \hich\af0\dbch\af13\loch\f0 
Unified Modeling Language (UML) allows you to draw an Object Model.  Given this object model in the form of XML Metadata Interchange (XMI), Pymerase can produce many different types of output using it's pluggable input/output module design. The ParseXMI i

put module reads in the Object Model and populates the Pymerase API with information that output modules need to use. Here is a list of just some of the output modules that currently exist and a brief discription.

Note that Pymerase, in it's current state, does not take advantage of all the features provided by UML.  At the same time, UML does not provide all the information you may want to provide to Pymerase.  In this document, I will go over the features
\hich\af0\dbch\af13\loch\f0 
 of ArgoUML which are currently used in Pymerase.  If you find that UML does not provide all the information, you can use the CreateTableXML output module to create XML files that describes your model. This will provide you with a way of adding more infor
\hich\af0\dbch\af13\loch\f0 m\hich\af0\dbch\af13\loch\f0 ation to your model.

\par }{\insrsid3224836 \hich\af0\dbch\af13\loch\f0 
When it comes to programming, naming conventions vary from programmer to programmer and from situation to situation. In the Java world, it's common to haveThisConvention while databases most commonly have_this_conve\hich\af0\dbch\af13\loch\f0 
ntion. This led to the development of Name Manglers in Pymerase. This allows different naming conventions to be converted to others. Here's a list of a least some of the NameManglers available.

\par 
\par \hich\af0\dbch\af13\loch\f0 
In some cases you may find you need to generate code to use with code or a database that uses allowercasenospaces convention. If this is the case, it is possible to get Pymerase to do what you want. It's just a little harder. You can accomplish this by us

\par }{\insrsid3224836 \hich\af0\dbch\af13\loch\f0 Before we jump in to the tutorial, let me describe the model we wish to create. The goal is quickly create a Database, Python DBAPI, and GUI for keeping track of Dvds in a col\hich\af0\dbch\af13\loch\f0 
lection. To keep it simple all we will just have two classes in our Dvd Database. The first will be a Dvd class which will contain the title of the movie, the year the movie was released, and a link to a single Studio class. The Studio class will contain 
\hich\af0\dbch\af13\loch\f0 t\hich\af0\dbch\af13\loch\f0 he name of the studio which produced the movie. We will allow a Studio have 0 to N Dvds, but will only allow a Dvd to have 0 to 1 Studios.
\par 
\par \hich\af0\dbch\af13\loch\f0 Note that this may not be the best design for a Dvd Collection Database, but it does get across the point of how to \hich\af0\dbch\af13\loch\f0 
use Pymerase and it will function. We would love to have more example databases or expansions on existing ones. If you would like to contribute, please visit http://pymerase.sf.net/ and send a message to the mailing list.
