FWIW, in the server side JavaScript realm, there has been growing
interest in following the WebSimpleDB API as an generic API for
interchangeable data storage systems, to provide a consistent
interface for interacting with various DBs like MongoDB, JavaScriptDB,
CouchDB, and even to some degree relational DBs (of course most DBs
provide additional DB-specific funcionality). We are closely following
the development of this API, since this is such an important part of
JavaScript applications on the server, but I am in support of what I
see so far.
Thanks,
Kris
