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?
