[orm-devel] Unified Connection Strings

[Diedrich Vorberg]

A good day to everyone :-)

I'll have to make a design decision regarding orm and I'd like to 
hear your opinions on this:

Writing the test programs I would have liked to add the ablility to 
pass connections parameters as a single string on the command line. 
Here I used -u -d -p parameters to get around this. Now I'm writing a 
ORMDatasourcePool Product for Zope and ran into the same problem: how 
to specify database connection parameters in a unified way.

There are two approaches I'm considering (any more ideas very 
welcome): PostgreSQL's DSN syntax:

   dsn = "adapter=pgsql dbname=test user=diedrich password=secret"

or the JDBC style urls

   url = "pgsql://diedrich:secret@localhost/test"

Personally I like Postgres' way of doing things better: easier to 
read, easier to parse and all in all very practical. The url style's 
advantages are: they are used by one of the most popular database 
access infrastructure and they fit into a single string on the command 
line.

Does anyone know who else is using this url style notation? Is there 
a standard like an RFC or so? Do you think it's worth the effort to 
support both?

Any comment is very welcome!
