API/Protocols: Java, Tinkerpop (which provides Gremlin, REST, Frames, Ripple and Linked Process)
Consistency: Flexible (from ACID, to relaxed)
Indexing: Flexible (from automatic to manual)
Persistence: Java class based.

4. Creating a Database GraphFactory.create(dbname)

5. Boot file
The boot file (mySystemName.boot) includes all the information needed to open a graph database.
When an application interacts with a graph database, it establishes the connection through the boot file.
The boot file lists the location of the graph's system database file (mySystemName.fdb), which is a binary file that stores information about your graph.

6. Using the database GraphFactory.open(dbname)
GraphFactory.open(dbname,propertiesfile)

7. Adding data
The first time persistent elements are added to the graph, DATABASE files are created to store those elements, and the locations of those database files are added to the system database file. The schema definitions for the elements are also added to the system database file.
Each new persistent element is given a unique identifier and stored in the appropriate database file (handled by InfiniteGraph's managed placement system).
As applications make updates to the graph, JOURNAL files are created. These files are used to return the graph to its previously committed state if a transaction is aborted or terminated abnormally.

9. System Files
Vertex instances are placed in VertexGroup_n.systemName.DB
Edge instances are placed in EdgeGroup_n.systemName.DB
Internal information related to edges is stored in ConnectorGroup_n.systemName.DB.

10. Add vertices and edges Meets Calls Pays
Vertex vinita= myGraph.addVertex(new Person(“Vinita”));
Vertex shalini = myGraph.addVertex(new Person(“Shalini”));
Vertex shraddha= myGraph.addVertex(new Person(“Shraddha”));
Vertex rajvi= myGraph.addVertex(new Person(“Rajvi”));
vinita.addEdge(new Meeting(“Denver”, “ ”), shalini);
shalini.addEdge(new Call(timestamp), shraddha);
shraddha.addEdge(new Payment( ), rajvi);
shalini.addEdge(new Call(timestamp), rajvi);
