As have I.Any interest in developing a google app engine backend for sqlobject? See http://code.google.com/appengine/docs/datastore/Only if someone does the job. And with the following caveats: -- I don't know if the docs provide enough information about low-level details; currently I see the docs mostly concentrated on Django ORM, I don't know if it's possible to write an SQLObject connection class at all; -- this is a commercial storage that I don't have a test access to, so the driver will always be underdeveloped and undertested unless someone provides a steady stream of patches - a situation similar to "second-class citizens" of SQLObject like Sybase and MaxDB. Oleg. The Google AppEngine appears to use Bigtable (http://labs.google.com/papers/bigtable.html). This is not a relational database. However, I get the impression from the "Camp Fire" that free access is available for development and testing.Yes, it's not a relational database, but in practice all this means is that you can not make joins (I think). You can still query a single table for various properties, order the result, and iterate over them. There are one-to-many and many-to-many relationships too. So it seems to me that a good portion of sqlobject is applicable but of course certain parts will have no meaning (like joins). I've already signed up for an account but haven't heard back from them yet. You might Google for E. F. Codd. From that, I think you'll see that more than joins are involved. Which is a problem in its own right. It seems that Google envisages links between objects, this was the basis of pre-relational databases. Colin W. |
