In my current project, I am trying to unify query language for accessing heterogeneous database. Heterogeneous database means their query language for accessing data is different. For instance, SQL is a query language for accessing data from Apache Derby, while nonSQL for MongoDB.
My question is “Is there any domain specific language, which have been proposed to unify heterogeneous databases ? “
Please feel free to direct me other efforts as well.
That’s quite an interesting question. There is at least one proposed solution called UnQL (Unstructured Data Query Language) – http://www.couchbase.com/press-releases/unql-query-language.
I suppose out of the box UnQL will work at least for CouchDB and SQLite. This just seems to be a great step ahead.
Personally I would say such a task seems to be a tricky one because of the conceptual differences between structured and unstructured data approaches. Anyway, it should be relatively easy to develop such a DSL for a well defined SQL and NoSQL data models used by a certain application.
