Re: Document Database Query Language

I have been thinking along the lines of a common query framework or even a document mapper for a while.
It is probably possible in a sense, but having an entirely common interface would leave it somewhat decimated as some features just aren't there for some document stores.
It's an interesting idea, but I can't really decide if it's only just that - interesting, but not really practical, usable or desirable.
In the end, I would probably prefer a framework specialized towards the database product I'm using rather than one that is riddled with trade-offs for supporting the ones I'm _not_ using.

Alex,

The benefit would be small, for sure, unless the framework simplifies the data access by aligning it more to how we are used to do CRUD.
I wouldn't limit such a framework to only a query language, but also include, or even focus more on, mapping/serialization of objects.

Compared to the JPA effort, I think that the challenge to design a common API/query language for document stores is a different beast entirely.
As the relational databases are more aligned to each other, especially with their mostly common query language, they obviously lend themselves better to these kind of abstractions.

If the different document databases somehow would agree on a common language, that would change the game completely, though.
Personally I think the MongoDb folks are on the right track - since the storage format is usually JSON or JSON-like, it makes sense to me to query it using javascript.

But don't get me wrong - I'm not trying to say that this is a fools errand. I'm just thinking out loud.

js2-mode indentation doesn't suck. It's just drunk.
