Enhancing sequence Manager documentation
Could we perhaps enhance the documentation of the sequence managers by
providing the corresponding table/column definitions for the examples
for (at least) the most prominent databases ?

ok, agree this will helpful. A link to the "OJB internal tables page -
Platform" will be helpful too
http://db.apache.org/ojb/platforms.html

What do you mean with "look different". In that case you don't use any
additional tables. ahh, assume you mean the database type of the column
(e.g. IDENTITY for hsql).

This would be great improvement!

+1, and a note that if 'auto-sequence' was enabled OJB will do the job
for you.

Nope, just what the corresponding table/columns look like in the
database. E.g. for high-low etc. this is a plain table (without any
identity/autoincrement stuff which should be pointed out to the
reader). But for NativeImpl and some others (MSSQLGuidImpl ?) the
tables look different, so examples would be a great help.
This is similar to the StoredProcedureImpl, which btw. could also provide
examples for other databases that support stored procedures (DB2 ?,
Postgres ?).
Likewise, it would be helpful if we provide at least pointes or also
examples for definining sequences in the various databases.

I don't understand what you mean, but I provide myself to review all
enhancements ;-)
Do you mean the system table names and entries set when using
SequenceManagerNextValImpl?
