Hi, A link is just a physical pointer, eg.
Record 1: {@rid: #12:0, name:"John" } Record 2: {@rid: #12:1, name:"Frank", friendOf:#12:0 } the friendOf attribute here is a link. Given Record 2, you can easily find Record 1 following the link, but if you only know Record 1 you have no information about connected nodes. An edge is a bit more complex structure, it's actually a document: Vertex 1: {@rid: #12:0, name:"John", out_friendOf:#13:0 } Edge: {@rid: #13:0, out:#12:0, in:#12:1, since: 1/3/2015 } Vertex 2: {@rid: #12:1, name:"Frank", in_friendOf:#13:0 } As you can see, the underlying structure relies on links (out/in_friendOf on the vertices and out/in on the edge), but - the edge is a document, so it can have properties ("since" in this case) - you have links on both sides, so you can efficiently traverse the edge in both directions Thanks Luigi 2017-03-15 13:12 GMT+01:00 thulaseeswara reddy gajjala < tech.esw...@gmail.com>: > hi > when we use edges and when we used links in real time scenarios.
