Introduction to Graph Databases with detailed installation steps, cypher query language examples, demos and visualization tools like RedisInsight. It also contains benchmarks for RedisGraph against Tigergraph, neo4j, neptune, Janusgraph and Arangodb. I mentions differences between native and non-native graph databases. It contains usecases for the graph databases and provides a score for selecting graph DB over traditional SQL and NoSQL DBs.

●Schema Less
●Cypher Query Language
●Supports Aggregations, Arithmetic exp., Sorts, etc.
●Tabular Resultset
●Faster & Better bulk loading

14. Installation

15. RedisGraph Installation
# Ubuntu/Linux
$ sudo apt-get install build-essential cmake m4 automake peg libtool autoconf
# Mac
$ brew install cmake m4 automake peg libtool autoconf
$ git clone --recurse-submodules -j8 https://github.com/RedisGraph/RedisGraph.git
$ cd RedisGraph
$ make
On successful execution, compiled binary could be found at:
src/redisgraph.so

16. Cypher Query Language
●Open Standard - Supported by several Graph DBs
●WHAT rather than HOW
●Pattern matching
○ ASCII art for Graphs
■ () : node
■ - - > : relationship
●Most clauses from SQL
MATCH (e:Event)-[presented_by]->(p:Person)
WHERE e.name = “RedisGraph”
RETURN e.name, p.name

17. Commands

18. Commands
●GRAPH.QUERY [GraphName] [Query]
● GRAPH.EXPLAIN [GraphName] [Query]
●GRAPH.DELETE [GraphName]

19. A Quick Demo

20. CREATE (:Rider { name: 'Valentino Rossi' })-[:rides]->(:Team { name: 'Yamaha' }),
(:Rider { name: 'Dani Pedrosa' })-[:rides]->(:Team { name: 'Honda' }),
(:Rider { name: 'Andrea Dovizioso' })-[:rides]->(:Team { name: 'Ducati' })
MATCH (r:Rider)-[:rides]->(t:Team)
WHERE t.name = ‘Yamaha’
RETURN r, t
MATCH (r:Rider)-[:rides]->(t:Team { name: 'Ducati' })
RETURN count(r)
