Subject RE: AutoBuildDb proposals
Date Thu, 02 Jan 2003 19:45:58 GMT

I just recently joined the OJB dev list after experimenting a bit with OJB for my own project.

What is the goal of the AutoBuildDB tool?

I have created some XSL templates that can build an OJB repository.xml file from Torque database
schema XML files and then another one to create OJB persistence classes from the repository.xml
file.  I also have ANT tasks defined to build my DB using Torque, generate the repository.xml
file, generate the persistence classes, compile the classes, and jar them up ready to use.

Right now my XSL transforms are quite rough, but they are successful in parsing foreign-key
relations defined in the Torque XML schema to create 1:1, 1:n, and m:n non-decomposed object
relationships within the repository.xml and the generated persistence classes.  I have started
a new project using these tools as a foundation for managing my DB and persistence classes,
and it seems to be working for most cases I have run into using postgreSQL.

So I am wondering how this fits into the goals of the AutoBuildDB tool to see if I can contribute.

+1 if you think torque is the better way, do it.
