NAME

Autodia::Handler::Torque.pm - AutoDia handler for Torque xml database schema

CONTENTS

INTRODUCTION

This provides Autodia with the ability to read Torque Database Schema files, allowing you to convert them via the Diagram Export methods to images (using GraphViz and VCG) or html/xml using custom templates or to Dia.

SYNOPSIS

use Autodia::Handler::Torque;

my $handler = Autodia::Handler::dia->New(\%Config);

$handler->Parse(filename); # where filename includes full or relative path.

Description

The Torque handler will parse the xml file using XML::Simple and populating the diagram object with class, superclass, and relationships representing tables and relationships.

The Torque handler is registered in the Autodia.pm module, which contains a hash of language names and the name of their respective language.

An example Torque database schema is shown here - its actually a rather nice format apart from the Java studlyCaps..

<?xml version=1.0 encoding=ISO-8859-1 standalone=no ?>

<!DOCTYPE database SYSTEM http://db.apache.org/torque/dtd/database_3_0_1.dtd>

<database name=INTERPLANETARY>



  <table name="CIVILIZATION">
    <column name="CIV_ID" required="true" autoIncrement="true" primaryKey="true" type="INTEGER"/>
    <column name="NAME" required="true" type="LONGVARCHAR"/>
  </table>

  <table name="CIV_PEOPLE">
    <column name="CIV_ID" required="true" primaryKey="true" type="INTEGER"/>
    <column name="PEOPLE_ID" required="true" primaryKey="true" type="INTEGER"/>

    <foreign-key foreignTable="CIVILIZATION">
        <reference local="CIV_ID" foreign="CIV_ID"/>
    </foreign-key>
    <foreign-key foreignTable="PEOPLE">
        <reference local="PEOPLE_ID" foreign="PEOPLE_ID"/>
    </foreign-key>
  </table>

  <table name="PEOPLE">
    <column name="PEOPLE_ID" required="true" autoIncrement="true" primaryKey="true" type="INTEGER"/>
    <column name="NAME" required="true" size="255" type="VARCHAR"/>
    <column name="SPECIES" type="INTEGER" default="-2"/>
    <column name="PLANET" type="INTEGER" default="-1"/>
  </table>
</database>
