Hey Torque developers,

I was hoping a couple of you could take a minute to bring me up to speed on some of the features of the project and it's direction to see if it will meet some of my companies needs.  Thank you in advance for your time and help.

Our company uses Maven for the majority of our projects and we have need of a tool that will allow us to easily manage various DB schema's and export schema descriptions to something easy to track in source control.  Basically I've inherited an old Oracle schema for our app with little documentation and a trail of old SQL Scripts and we're planning a migration to SQL Server and some new application schema changes very soon so I need to get my ducks in a row.  We are CVS dependent and being able to track schema changes in a text format allows for nice diffing between revisions.  My managment is also unlikely to spring for a tool like ER/Win, I'm not sure I need that much functionality, and the ER/Win data files don't diff well at all.  Currently we have an existing persistence layer so honestly we wouldn't be making much use of that aspect of Torque for now so I'm mainly concerned with it's ability to help me with administrative DB schema management and work smoothly with Oracle and SQL Server (which the new Microsoft drivers seem to allow it to do).  Torque seems to provide some of this functionality and I was wondering what the "plan" was for the Torque project with regard to more advanced schema management with regards to some of the following subjects.

1) Currently only the table and view structures are exported from the schema, what about procedures, functions, users, etc.
2) Does Torque allow one to compare physical DB schemas, xml schema files, and SQL scripts for differences and to generate SQL Scripts for performing those differences?
3) Are there any nice XSLT templates out there for turning Torque schema XML into nice DB documentation?
4) Has anyone though of making a very simple Maven target or Torque task called torque:driverInfo or something that dumps out all the interesting driver information about supported features and syntax (see java.sql.DatabaseMetaData object methods) for the user to see?

If I convince myself that Torque offers enough features to be useful to me I'm perfectly willing to actively contribute to the effort with bug reporting and code including a class for point 4 above and extensions provided in point 1.  If I can't get what I need from Torque I probably can't justify the time to actively contribute much given my work schedule so please help me understand what direction the project is taking and what features I can expect to make use of and if you think any of my questions or ideas above would make sense.

Many thanks for your help and consideration!

Best regards,

the primary goal of the torque generator was to generate everything 
needed to use the torque runtime environment (om/peer model, sql scripts 
to create the db)
based on the existing functions it should be possible to extend it as 
needed ...

you can use nextobjects if you need a gui to edit the schema.xml files ...

i don't think there is a way to handle this for different rdbms ...

hope he'll send some patches soon ;-)

there is a task to generate html or xml docs .. the xml docs are in 
anakia format so you can integrate it with your other maven xdocs

no, but it should be easy to do it ... what's the use case for this 
extension??

any extension to torque is welcome .. but it doesn't help to have cool 
features for on rdbms if they are not supported on all others .. so if 
you paln to extend toprque make sure the extension will also work on 
other rdbms ..
