Re: [android-developers] ORM library

I have looked at quite a few ORM libs but have always decided to go
without them.

I think that ORMs works a lot better in dynamic language environments
like PHP and Ruby. That is just my personal opinion - they might work
just fine.

Secondly my main concern when writing apps for Android is the overall
device power consumption that my apps inflict. I have absolutely no
empirical data to support the following statement - but my general
conception is that computing and I/O is very expensive and should be
avoided at all costs. It is also my thought that ORM libs doesn't help
me do as little (especially I/O) as possible.

So - the main reason I have chosen to go without any ORM lib so far is
that weighing the complexity and maintenance of the domain model
against the hand writing and optimizing of SQL clearly favours the
hand-written approach. This is clearly because of a very limited
domain and "deeper" apps with data only slightly more complex might
benefit greatly from using an ORM lib without taking any significant
performance or battery consumption impact.

The ORM library I have been most pleased with (as far as I remember)
is OrmLite: http://ormlite.com/sqlite_java_android_orm.shtml

If you gather any experience please share - it would be interesting to
hear about cases where using an ORM library "saves the day" ;-)
