问题 I'm having a bit of difficulty in figuring out how to get the OrientDB JavaScript API to work in a web app. I tried searching into the source code of the OrientDB Studio web app and was able to notice that they use the orientdb JavaScript API along with some AngularJS, which looks very fascinating, but then I tried on my side by creating a simple web page that imported the orientdb-api.js and the jquery library, and it did not work. Here is the content of my web page: <!DOCTYPE html> <html>

问题 In Node, what is the correct way to execute Gremlin queries against a database? My current attempt using the Official Node OrientDB Driver: const { ODatabase } = require('orientjs'); const db = new ODatabase({...}); db.query('g.V()') .then(console.log, console.error); And I get: OrientDB.RequestError: Cannot find a command executor for the command request: sql.g.V() DB name="mynevo" at child.Operation.parseError (.../orientjs/lib/transport/binary/protocol33/operation.js:864:13) However, when

Edge properties clobbering vertex properties in OrientDB from ETL

由 和自甴很熟 提交于 2019-12-08 02:04:30
问题 This is a follow-up to another question I had posted regarding importing a simple database into OrientDB using ETL that had both edge and vertex properties with dates on both. Here's my data: vertices.csv : label,data,date v01,0.1234,2015-01-01 v02,0.5678,2015-01-02 v03,0.9012,2015-01-03 edges.csv : u,v,weight,date v01,v02,12.4,2015-06-17 v02,v03,17.9,2015-09-14 For brevity, I'll add just the updated commonEdges.json file using the edits from the other question. The other JSON files are

OrientDB System Requirements

由 主宰稳场 提交于 2019-12-08 00:44:29
问题 What are the minimum reasonable memory and CPU requirements for OrientDB in a light-use production scenario with a relatively small database? I realize that "the more the better" is probably the answer, but I'm really just looking for a starting point based on anyone's real-world experience (i.e. "less than X just isn't workable"). 来源： https://stackoverflow.com/questions/37038403/orientdb-system-requirements

Orientdb as a document-graph database

由 你。 提交于 2019-12-08 00:27:23
问题 I am using Neo4j and trying to find out the advantages of Orient as document-graph db over Neo4j. How does it work in Orientdb to have features of a document database in a graphbdb? is the database in both mode (graph and document) using the same datasource? if so, then is it possible to edit data in documentdb and show it as a graphdb? I worked with Orientdb and it seems that you can have your database either as graphdb or as documentdb, so I don't get the point of having both databases
