Boris, What is the class/type of the keys in your example? Are the keys simple objects (String, Number, etc.) or complex (Person, Employee, Customer, Student, Product, etc.). With any remote database the challenge will be populating the result into your local image. How deep/complex is the result? That is, if only one dictionary satisfied your sample query, how many objects would be reached and what would be their classes? How large is the "huge" parent dictionary? Millions? Billions? Do you need the client Pharo image(s) to be remote from the database? What sort of network is between them? Naturally, my inclination would be to investigate GemStone/S, but various factors would influence the decision.

Hi all,
I have a need to persist a really large and funny object structure in Pharo (a huge Dictionary of Dictionaries) and I would like to be able to query this data from a remote image.
Basically what I am looking for is some form of database that would allow me to input elements in to this structure from one image, and read them out in another image with queries like i.e.
dictionaryOfDictionaries select: [ :each | (each keys includes: key1) and: [ each keys includes: key2 ] ] It does not have to be strictly an OO database, anything that could enable me to do this fast and easy would be nice.
Any suggestions/ideas/comments?
