DB Designer XML to Propel Schema XML
|
|
|
|
==== Author: Jonathan Graham <jkgraham@gmail.com>
|
|
==== Version: 0.5 (2008-01-25) (http://blog.tooleshed.com/?p=6)
|
|
==== Description:
|
|
This XSL will transform a DB Designer 4 database model XML file into a
|
|
Propel database schema file. This allows you to design your database
|
|
model using DB Designer 4 (models are saved in XML format) and then
|
|
easily create the Propel database schema file.
|
|
|
|
The PROPEL properties that this XSL will translate are listed below.
|
|
|
|
TABLE: name, description
|
|
COLUMN: name, primaryKey, required, type, size, scale, default, autoIncrement, description
|
|
FOREIGN-KEY: foreignTable, name, onDelete
|
|
REFERENCE: local, foreign
|
|
INDEX: index (not related to FK), unique, fulltext
|
|
|
|
==== Usage:
|
|
- Simply feed this XSL into your favorite XSLT engine along with your DB Designer
|
|
XML model. The resulting output is a Propel database schema XML.
|
|
|
|
==== Collaboration:
|
|
Peter Banik <peter@froggle.org> - UNIQUE TAG
|
|
Benedicto Franco Jr. - MULTIPLE FOREIGN KEY, DATABASE NAME
|
|
Martin Kreidenweis <martin@kreidenweis.com> - Bug fixes, INDEX
|
|
Michiel Hakvoort - onDelete
|
|
Michel D'HOOGE - FULLTEXT
|
|
Oleg Marchuk <kingoleg@mail.ru> - version 0.5
|
|
|
|
==== Software:
|
|
Propel: http://propel.phpdb.org/
|
|
DB Designer 4: http://www.fabforce.net/dbdesigner4/
