[jQuery] JSON datastore

[shavin]

Is there anything similar to dojo's datastore in jQuery? I wish to try
build an elementary kind of a single-page self-saving client-side
javascript application similar to Tiddlywiki based around a database
of student's records. Although I don't hope to make it as
sophisticated as Tiddlywiki!
I wish to express and save the data in form of json objects. Any ideas
or comments on this would be highly appreciated.
