Hi Stef, The Neo4j Cypher queries express a subgraph/path that you want to match in the big graph (nodes and edges with attributes). No fragmentation due to normalization etc., so no joins, it’s more like a regex matcher: MATCH p=(x:PERSON)-[:KNOWS*]->(:PERSON) WHERE x.name = 'John' RETURN p;

We could talk to the guy to see if he wants to revisit the license. and you can decide to load GPL in your app and be happy. I hope that omnibase will be ported to pahro in the future. On Tue, Dec 26, 2017 at 9:30 PM, Offray Vladimir Luna Cárdenas wrote: > But if VOSS

I’ve always liked Neo4j to persist object graphs. Also has a nice query language. The database is not fool-proof (isolation issues, out of memory on expensive queries), but works fine for analytics. > On 25 Dec 2017, at 10:43, Ian Ian wrote: > > Hi All, > > Thoughts of

But if VOSS is GPL, that doesn't imply that, when ported, all Pharo could become GPL, as discussed time and again in the list? Cheers, Offray On 25/12/17 10:01, Stephane Ducasse wrote: > the author of omnibase told me that he always wanted to port it to > Pharo. But may be someone should do it.

the author of omnibase told me that he always wanted to port it to Pharo. But may be someone should do it. There is also VOSS that is open source even if GPL that could be ported to pharo but this is an effort too. Stef On Mon, Dec 25, 2017 at 10:43 AM, Ian Ian wrote: > Hi

Wasn’t there an attempt to port Magma over from Squeak? That would sound like a nice alternative. Or Gemstone, of course. > Am 25.12.2017 um 10:43 schrieb Ian Ian : > > Hi All, > > Thoughts of a purely OO nature? > > :)

Fuel (present in the image) is nice, but not compatible from one image version to another one. Hilaire Le 25/12/2017 à 10:43, Ian Ian a écrit : Hi All, Thoughts of a purely OO nature? :) -- Dr. Geo http://drgeo.eu
