So coming back to Pharo realm, this is why I think ORM is really important for us, and I'm really happy this discussion finally took place.
But one of his points was that ORM layers made SQL obsolete by hiding much of its power, the ability to do (query and other) processing on the DB.
You're right. But once stored in a RDBMS you can do a lot of things with the data, using all its power. I certainly don't expect to do OLAP with millions of rows converted to objects in the client (Pharo) side. As a disclaimer I have to admit I'm completely ignorant of "BigData" things such as Hadoop and similar, I barely grasp their main purpose.
BTW, I don't think there is such a thing as transparent persistency.
Certainly there isn't. Particularly for Objects. Regards! Esteban A. Maringolo
