I don't know RoR at all but is this similar to the proposal on the
wiki for Zend_Db_Schema_Manager? - http://framework.zend.com/wiki/display/ZFPROP/Zend_Db_Schema_Manager+-+Rob+Allen
Hi Sander, I've put some thought in to db migrations because it was a
part of RoR that I both really liked and found somewhat over-
simplified.
On the one hand, I thought the RoR implementation was an elegant way
to
version application schemas and it lent a helpful tool to a pretty
vital
best practice. On the other, I felt that the ruby-based DDL
abstraction
was rather toy-like and one would quickly revert to 'execute' and
standard SQL DDL/DML in real environments. Admittedly, I haven't
tested
the limits of db:migrations, but the differences in ddl among- and in
the objects that can be created in- different DB's combined with the
relatively minor savings in complexity and database 'independence'
left
me less impressed than with other parts of RoR. As always, I'd love to
hear about other opinions and experiences with different frameworks.
For ZF, my current preference would be for raw sql-script-based
migrations with the possibility of supporting or providing
extensibility
for future support of files and possibly other non-code application
artifacts. Basically it would aim to be a simple versioning/
environment
setup tool that is much easier to use- but no less powerful than-
shell
scripts. Questions that I haven't fully thought through include:
Should
we support only one usage pattern over others- like sequential
versioning over schema management simplification/separation? Would
it be
feasible to generate raw sql-scripts if we decide we'd like to do that
in the future, or would we rather be generating a sort of
'intermediate
language' much like RoR migrations? Are there any useful integration
points with CVS/SVN? And the list goes on and on. . .
Right now I'm putting together a proposal for a CLI tool that
(hopefully) reflects some of the best ideas out there but doesn't
skimp
on flexibility. I would love to see someone working off the draft
proposal to provide migrations. ;)

Subject: [fw-general] db migrations
Hi!
I was wondering if someone has any thoughts on db migrations in
combination with ZF. I have some great deployment scripts ready for
pushing out my application code, but I was wondering how to get db
migrations up and running in an easy way.
I have looked at the Cake db migrations, but it's too much mixed with
the Cake console. I also looked at liquibase (liquibase.org), but it
has a pretty bloated xml config, and I prefer some sort of yaml or
perhaps sql migrations.
Anyone any ideas or suggestions?
