Packaging Database Applications

Not strictly a technical question but I hope this is the most appropriate forum.

I'm writing an application that will work with a number of database platforms by limiting myself to simple tables and indexes. I am just a little concerned about the level of complexity required to install the database schema and also the steps required to update the users database overtime as new versions come out. The JDBC API seems to have a lot of functionality to extract metadata etc. Has anyone tried to create application schemas entirely from Java and if so could they share their experiences.

I was thinking of storing the database structure in an XML file and on application startup verify that the database is both present and up-to-date.

Is this feasable and practical or would it be better to handle this outside of java using regular SQL scripts etc ?

Thanks in advance

Dave,
It sounds like you want to verify the database setup after installation. It is a sound idea to want to write a verify script in Java. And since your application is dependent on the version of the schema, application startup is a good place to do this.

It definitely sounds feasable and practical. It also sounds like a very robust solution.

And yes - this is the correct forum for such questions. Basically, anything that has to do with a database should go here.
 
It is sorta covered in the JavaRanch Style Guide.
