In DAL it can be done like one single command:
db.define_table('my_items',
Field('name', 'string', length=100),
Field('description', 'string', length=400),
Field('priority', 'integer'),
Field('creator_id', 'reference user'),
Field('dept_id',
Can you provide an example of a request that involves the kind of
synchronization you are looking for?

Using SQLAlchemy as data mapper below.

Well the DAL already implements the data mapper pattern. The memory
representation are the tables defined in the models, the persistent
representation can be anything really, you could make your own adapter.
As for the Domain Model Pattern an easy approximation is using methods
and virtual
I suppose it depends on what you mean by this application logic

So you certainly can have that completely independent, though you wouldn't
persist anything. Is the idea that you'd update a memory representation of
objects only, and somehow
Simple is a relative term, I should not have associated it with web2py DAL.
What I meant is that I want to make my application logic completely
independent from persistent data storage. The only method I know to
implement this is using the data mapper design pattern

You could see DAL as a scoped ORM i.e. for specific kind of objects, these
object are Table(s) containing Field(s) and the way to manipulate those
objects mimics as much as possible the relational model. By no mean DAL is
thin. As a matter of fact it allows extremely sophisticated thing like

Our corporate standard OS is 32 bit Windows Vista.
The Sybase driver list at sourceforge.net is only for Windows XP which will
not work.
I searched internet and it looks like the only good sybase driver is one
that has to be purchased.
There is also one with source which has to be built but that
Hi:
FYI - we did a lot of work to setup the corporate sybase environment and
successfully connected to sybase using
the sybase client tools Thursday night. And we installed and tested the
web2py Welcome app on the corporate laptop.
We expect to start trying the web2py sybase adapter on Monday.
web2py includes an adapter but nobody has tested it. If you can help us
test it we can help you debug any problem that may arise. Compatibility
with sybase and other SQL DB engines is a priority.

Please point me to the sybase adapter.
There are 2 of us developers here at work who can test it for you on a
large corporate sybase database.
Thanks.

No preference on which python driver for sybase.
So whatever you select is fine with us.

I just committed a SybaseAdapter using this driver:
http://python-sybase.sourceforge.net/
It extends the MSSQLAdapter but uses the other driver and Sybase types.
It needs testing.
You can use it with
DAL('sybase://dsnstring')
or
DAL('sybase://username:password@hostname:port/dbname')
It uses
OK I will download the trunk and try it tomorrow.
Thanks.
