GQL catalog system
So far, you’ve explored elements that exist within the graph. In this section, you will delve into additional elements outside the graph using GQL.
The GQL standard also introduces the catalog system, which organizes GQL objects into a structured hierarchy. Catalogs classify objects as either primary or secondary. Understanding this system is crucial for managing and navigating GQL components effectively.
GQL objects
The following list describes the primary and secondary GQL objects (see Figure 2.6 for a diagram of GQL objects):
- Primary GQL objects: These objects may hold other GQL objects. They include the following:
- GQL directory: Can be the root catalog and contains other GQL directories or GQL schemas
- GQL schema: Can be the root GQL catalog and contains graph, graph type, binding table, and named procedure
- Graph and graph type: Represent specific graph instances and their types
- Binding table...
