Are there any Design Guidelines for Documental Databases?

Just wondering if there are any kind of guidelines for when you are designing a document-oriented db and I am talking especially about CouchDb.

I know that being schemaless things can take the shape that we want but, are ther开发者_C百科e any best practices?

Thanks in advance! =D

Jan Lehnardt recently wrote up a useful overview of data modeling (I would not quite call it "schema" design as you correctly point out).

I don't know specifically about CouchDB, but there is something over in the MongoDB Docs about Schema Design.
