Hi, everybody, I work in a lab at University of Western Ontario, with humanists people. The needs of the humanist research make useless the current SQL databases because it's hard to change the schemas or build queries with several JOINs. So, we are developing a system which mixes a relational database and Neo4j.
Sylva [1], as it's called (previously Graphgamel), stores all data in the Neo4j database as a graph. On the other hand, de multimedia files (image, video and audio files) are stores using the relational one (over Django). Besides, the relational part allows the definition of lazy and dynamic schemas, very usefull to model the world from the humanistic point of view. The users can create nodes and relationships but according to a certain kind of integrity defined in the schema. Sylva also has a very early version of visualization through Raphäel and Processing.js. Here you can see some screenshots [2, 3, 4] and a video demo [5]. Our goal is to adapt the django-qbe project [6] to our schema tool in order to produce Gremlin queries in a visual way. But by now we are using the Neo4 REST component but it's not very fast and it has some limitations. It's an alpha version, but it goes without saying :-) [1] https://github.com/escalant3/graphgamel [2] http://dl.dropbox.com/u/2630535/sylva.png [3] http://dl.dropbox.com/u/2630535/plexigraph.png [4] http://dl.dropbox.com/u/2630535/grafo.png [5] http://www.youtube.com/watch?v=r04eV7vghfs (sorry, not subtitles or audio yet) [6] http://versae.github.com/qbe/ On Wed, Dec 1, 2010 at 12:52, Andreas Kollegger <[email protected]> wrote: > Would anybody be willing to share experiences with trying to introduce Neo4j > into a system with another relational (or other NoSQL) database? > > We're starting to think about best practices for integration: > * Hybrid data-modeling: what goes where? > * XA transactions > * message queues for data distribution > * data migration strategies > > Any problems or feature-requests related to living in a > multi-storage-platform world are welcome. > > Cheers, > Andreas > > > _______________________________________________ > Neo4j mailing list > [email protected] > https://lists.neo4j.org/mailman/listinfo/user > -- Javier de la Rosa http://versae.es _______________________________________________ Neo4j mailing list [email protected] https://lists.neo4j.org/mailman/listinfo/user
