Are there any Graph Databases that allow you to define the labels and relationships (schema) first

Question

I am looking to build a graph database for a new site that I'm building and came across neo4j.

Although it is a viable option, I don't like the idea of creating the labels and relationships on the fly. Instead I only want to define the labels and relationships before hand so my database can have a bit more stability to it.

Pretty much like a RDBMS where we define the tables and properties first but instead I want to define the labels and relationships and their properties first.

Answer 1

Titan allows you do that also.

• http://s3.thinkaurelius.com/docs/titan/0.9.0-M2/schema.html

Of particular interest to the original post, in section 5.5: It is strongly encouraged to explicitly define all schema elements and to disable automatic schema creation by setting schema.default=none in the Titan graph configuration.

Answer 2

OrientDB allows you to do that. Look at:

• http://orientdb.com/docs/last/Graph-Schema.html

Answer 3

One thing you can do is define this befor me the devoloper entered this in graph format (like a template?) for example, what is the node, it's properties, the relation...etc
