Hi all,

I would like to know if ist is possible to use Teneo with an already
exsiting Database.
The Database is from a comercial application so it could not be altered.
I would like to extract some of the data and modify it within an EMF
Application.

For Hibernate there are existing tools for reverse engeniering, but
it does not fit to EMF ot TENEO.


with kind regards

Hi Torsten,
No there are no reverse engineering tools for Teneo. It is an interesting topic though. However
afaics reverse engineering from a db (for Teneo) would also require tools for reverse engineering a
db schema to the emf model. As (afaics) the emf objects should be based on the relational schema. So
a relational schema to ecore translator would be the first step.

Ed (as you are back from holiday!), have you before seen this requirement/idea of generating an
ecore model on the basis of the db relational schema?

Hi Martin,

there is a missunderstanding. I would like to know if it is possible
to use TENEO with a existing database which could not be modified.
When I first generate the EMF Model and then let TENEO generate the database
there are several emf or teneo specific columns in the table. But in my
existing database these columns are not there.

And before I start learning TENEO and Hibernate I would like to ensure
that it will lead to something usefull.


Thanks


Torsten

Hi Torsten,
Ha, okay, Teneo will create additional columns for the following cases:
- econtainer relations (can be disabled using an option)
- id and version columns (if the types don't have those, can be controlled/disabled by options)
- index columns in list elements (can be disabled using options/annotations)

So overall I think you should be able to get very far in disabling emf/teneo specific columns. And
if you still encounter an issue then I am prepared to look at it and incorporate it in a new build.

See the options page for more details:
http://www.elver.org/hibernate/options.html

Also this page maybe of interest (to control naming of tables/columns/foreign keys):
http://www.elver.org/hibernate/extensions.html

Hello Torsten,

My client is a large health insurance firm. We are using EMF/Teneo on a
legacy database with ZERO modifications to the underlying database. You
do have to handle a couple of things in a slightly strange manner, but
so far we haven't found anything we cannot overcome. Mostly the
difficulty depends on how strange your legacy DB is. (We had some very
odd ball things in our database, but we've still made it work)

Also, I wrote a small script which turns SQL DDL calls into annotated
XSD. It works very well and only took a couple of days to write. If
you have a large number of tables to map, this can save a lot of work
since the script doesn't make any typos.

Hope that helps. Let me know if you have any specific questions and
I'll tell you if I've run into them yet.
