Graph Database Operations with platform specific adapters
STATUS: On Hold - Currently this project is on hold.
The GraphDB package is a simple node.js package designed to ease the process of working with graph databases. GraphDB provides high level graph operations (create node, link, etc) that are generally common amongst all graph databases.
The GraphDB package itself has no persistence capabilities in it's own right, but uses connector packages to implement store specific serialization:
To initialize a new graph, code similar to the following should be used:
var graphdb = require'graphdb'graph = graphdb connector: 'memory' ;
Using the above will create a graph that will only persist in the process memory, so this is probably not ideal. Rather, choose one of the persistence modules (see above) and initialize a db using appropriate connection details.
To create a new node in the graph, use the
create method of the graph object. For example:
var node = graphcreate name: 'Bob' ;console.lognodedataname; // --> Bob
The above is an example of creating an untyped node in the graph, but you can also created typed nodes, which have some distinct advantages:
To define a new type in the graph, use the
The above code will define a new type
profile, which will be accessible at
graph.types.profile. Our definition of the profile type specifies that it has a name attribute which is of type string. In addition to the specified
name attribute an
id attribute is also created which is of type
Now, if we create a new node of the profile type (specified in the 2nd argument of the
create method), we will be able to able to access the
name attribute directly through the a JS property accessor:
var node = graphcreate name: 'Ted' 'profile';console.lognodename; // --> Ted
The following is a list of data-types that are expected to be implemented by all graphdb connector modules:
