Rainer Döbele commented on EMPIREDB-217:
----------------------------------------
Hi Jan,
first I want to apologize for not giving you some feedback earlier on your
contribution.
Your contribution is really very useful and it fits perfectly in our
architecture.
I have added it to our current trunk so it now available with our
2.4.4-SNAPSHOT release.
I have added your classes in the package
org.apache.empire.db.validation
from where it now available.
Only the Oracle specific extension class OracleDBModelChecker has been added to
the package org.apache.empire.db.oracle.
The usage pattern is:
DBModelChecker checker = new DBModelChecker();
DBModelErrorHandler handler = new DBModelErrorLogger();
checker.checkModel(db, conn, "MY_SCHEMA", handler);
with the opportunity to override both the Checker and the Error Handler for
individual purposes.
I have tested it with a few databases and it really does a great job.
The only things that I have found are:
1. A missing foreign key relation that contains more than one column gets
reported once for each column it contains (i.e. a foreign-key over two columns
gets reported twice). Once would be enough.
2. For decimal columns in views I get a type mismatch reported that the type
DECIMAL does not match the database type of INTEGER. This is not a big issue,
but maybe we should try to fix it at some point in time.
Again in the name of our project community I want to thank you very much for
your great contribution Jan.
This feature will be a major benefit for our next release.
