Advanced Neo4j Use Cases with the GraphAware Framework
The document discusses GraphAware Framework, which makes it easy to build, test, and deploy custom APIs, transaction-driven behavior, and asynchronous computation functionality for Neo4j. It provides examples like representing time series data, tracking graph changes, assigning UUIDs, and running algorithms. GraphAware Framework is open source and supports building both generic and domain-specific Neo4j extensions.
