Alexander MeuerCan anyone recommend a comparison of Multi-model <a href="https://mas.to/tags/databases" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#databases</a>? Or even recommend one based on their experience? Currently evaluating <a href="https://mas.to/tags/ArangoDB" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ArangoDB</a>. Ideally looking for something without vendor lock-in (ie.

@haitchfiveSulpher is the little subset of Cypher (Neo4j's query language) that I'm working on.I added nore examples of queries that can be expressed in Sulpher: <a href="https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual_0.3.9-part3-basicgraph.md" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual_0.3.9-part3-basicgraph.md</a>Here are other graph features that can be accessed via the REST api without need of Sulpher (tSome of these endpoints translate your REST request to Sulpher under the hood) <a href="https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual_0.3.9-part4-graphoperations.md" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual_0.3.9-part4-graphoperations.md</a>In the Misc section there's a bit more interesting code example on how to use these graph things from your own Python application, or from wherever you can hit a RESTful http api. It implements the basics to access the graph data of a group of bloggers, with blogs, posts, tags, and comments.<a href="https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual_0.3.9-part6-misc.md" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual_0.3.9-part6-misc.md</a>Hope somebody finds it useful!<a href="https://oldbytes.space/tags/rserv" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rserv</a> <a href="https://oldbytes.space/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#python</a> <a href="https://oldbytes.space/tags/graphdb" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#graphdb</a> <a href="https://oldbytes.space/tags/foss" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#foss</a> <a href="https://oldbytes.space/tags/sulpher" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sulpher</a> <a href="https://oldbytes.space/tags/cypher" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cypher</a> <a href="https://oldbytes.space/tags/neo4j" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#neo4j</a>

@haitchfiveI'm expanding Sulpher (the little subset of Neo4j's Cypher I came up with) to be able to build more interesting graph queries.Here's where it's at now: <a href="https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual_0.3.9-part3-basicgraph.md" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual_0.3.9-part3-basicgraph.md</a>What's next:<ol><li>Variable-length path expressions </li><li>Advanced Relationship Handling (direction, multiple types)</li><li>More comprehensive Property-Based Filtering</li><li>Advanced Aggregation Functions and Clauses (WITH, ORDER BY)</li><li>Parameterisation</li></ol><a href="https://oldbytes.space/tags/rserv" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rserv</a> <a href="https://oldbytes.space/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#python</a> <a href="https://oldbytes.space/tags/rest" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rest</a> <a href="https://oldbytes.space/tags/graph" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#graph</a> <a href="https://oldbytes.space/tags/graphdb" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#graphdb</a> <a href="https://oldbytes.space/tags/cypher" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cypher</a> <a href="https://oldbytes.space/tags/sulpher" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sulpher</a> <a href="https://oldbytes.space/tags/neo4j" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#neo4j</a> <a href="https://oldbytes.space/tags/FOSS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FOSS</a>

@haitchfiveI'm working on rserv 0.3.8<a href="https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual-part5-graphs.md" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual-part5-graphs.md</a>Since 0.3.x rserv has incorporated certain graph-like features that allow you to query data from a property graph perspective.Any document stored in rserv for any given entity can now be treated as a node from the graph-like perspective.In order to perform graph queries, I added Sulpher, which is a funny name for a reduced subset of Cypher (the Neo4j query language).Now I'm more happy with the general design (and keeping it RESTful! unlike GraphQL!) I think I will be ready to make the first public release soon.<a href="https://oldbytes.space/tags/rserv" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rserv</a> <a href="https://oldbytes.space/tags/graphdb" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#graphdb</a> <a href="https://oldbytes.space/tags/graph" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#graph</a> <a href="https://oldbytes.space/tags/documentdb" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#documentdb</a> <a href="https://oldbytes.space/tags/cypher" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cypher</a> <a href="https://oldbytes.space/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#python</a> <a href="https://oldbytes.space/tags/REST" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#REST</a> <a href="https://oldbytes.space/tags/FOSS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FOSS</a>

Chris Engelbert / noctariusWhat do you think is the biggest advantage of graph databases?In last week's episode of my <a href="https://mastodon.social/@simplyblock" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@simplyblock</a> Cloud Commute podcast, I had an amazing chat with Jennifer Reif from <a href="https://mastodon.tech/users/neo4j" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@neo4j</a> talking about graph databases, the advantages of a graph data model and how easy it is to analyze even unknown datasets.You can find the full episode on Youtube (<a href="https://youtu.be/CdrWQp4Lw5A?feature=shared" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://youtu.be/CdrWQp4Lw5A?feature=shared</a>) or Spotify, Apple Podcast, and others (find the links at <a href="https://www.simplyblock.io/cloud-commute-podcast/episode/9d0152c9/getting-started-with-graph-databases-with-jennifer-reif-from-neo4j" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.simplyblock.io/cloud-commute-podcast/episode/9d0152c9/getting-started-with-graph-databases-with-jennifer-reif-from-neo4j</a>).<a href="https://mastodon.online/tags/neo4j" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#neo4j</a> <a href="https://mastodon.online/tags/graph" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#graph</a> <a href="https://mastodon.online/tags/database" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#database</a> <a href="https://mastodon.online/tags/relational" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#relational</a> <a href="https://mastodon.online/tags/graphdb" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#graphdb</a>
