RefArchitectureOverview

From the perspective of an application using HyperGraphDB, the main entry point is the HyperGraph class. This class operates at the level of the graph, handling operations such as adding and removing nodes and links, constructing run-time instances out of their types, managing predefined indexes and queries. The HGTypeSystem class manages hypergraph types and their mappings to Java types. The HGStore class handles low-level storage and indexing operations and interacts directly with a Berkeley DB data store. The query system implements low-level querying operations – low-level here meaning at the level of the database layout as detailed in the section on the HGStore below.
