Foundation
Property graph
Understand how property graphs use nodes, edges, and properties to model complex industrial systems.
Spaces, instances, direct relations
Construct an industrial knowledge graph using spaces, instances, nodes, edges, and direct relations.
Schema definition
Containers, views, polymorphism, data models
Define schemas using containers, views, and data models to bring your own properties into the knowledge graph.
System schemas
Explore globally available system schemas prefixed with cdf_ that provide out-of-the-box containers, views, and data models.
Working with data
Ingestion features
Ingest and remove instances in your graph using apply, patch, replace, and delete operations.
Query features
Query your industrial knowledge graph using filters, parameters, recursive edge traversal, and subscriptions to changes.
Search features
Search for text and property values in your knowledge graph using full-text queries, filters, and relevance ranking.
Aggregation features
Summarize and analyze data using aggregation functions, grouping, and filters.
High-performance storage
Records
Records are individual data objects that represent events, logs, or historical entries.
Streams
Streams are logical containers that organize your records and define how they behave throughout their lifecycle.
Management and inspection
Access control features
Control access to graphs using spaces and access control lists (ACLs).
Schema and instance inspection
Inspect schemas and instances to understand their structure and relationships in your data model.
