> We need a way to upgrade the database (for JPA store) whenever it is needed.
> In general, a database upgrade is needed further a JIRA that impacts the
> database.
> This can be:
> 1. On a db schema level (table, columns, fk, index,...)
> 2. On data level (update some data, feed a column with relation keys,...).
> Plain SQL would be enough for the first point (not for the second one). PLSQL
> (or similar) would be needed for the second point.
> To ease things, a java "software" process will developed based on the
> existing JPA layer.
> The tool should be invoked with JIRA numbers as parameters.
> Each provided JIRA number would invoke a DB Change Command.
> As POC (Proof of Concept), we will first develop a tool that takes into
> account.
