Open source graph database – Neo4j and Infogrid
Neo4j and Infogrid
Graph database uses nodes, edges, and node properties to represent the information. Relative to the traditional relational database, for example, MySQL, graph database is more suitable for the complex, highly interrelated information such as social network applications. For such applications, the relationship between friends is dynamic, evolving fast, which poses strong challenges to the relational database.
First of all, graph-database.org has an almost complete list of both open source and commercial license graph databases, worth to keep an eye on it.
(2) Infogrid, emphasize the Restful web development.
Both Neo4j and Infogrid use JAVA. If you are a JAVA developer, good to go!
Compared with Neo4j, inforgrid seems to be a new starter. Inforgrid has not got as many users as Neo4j. However, Inforgrid is released under single open source license, Neo4j is released under the dual license.
