    • A-E

      Edges represent relationships in data models, such as friend relationships in the social network, user rating and purchase behavior in the e-commerce transaction network, cooperation relationships between authors of a paper, and index relationships between articles.


      • F-J

        A graph is a data model composed of edges and vertices.

        GES provides distributed, at-scale, and integrated graph search and analysis capabilities. Its high-performance kernel supports high-concurrency, multi-hop, real-time queries in seconds. It also has extensive built-in graph analysis algorithm libraries to meet the application requirements of various fields.

        graph size

        Graph size indicates the graph scale, which is based on the number of edges. Its value is not an accurate one.


        Gremlin is a graph traversal language in the open source graph calculation framework of Apache TinkerPop. You can use Gremlin to create, read, update, and delete (CRUD) data, for example, adding vertices or edges, updating properties, and performing complex traversing.


        • K-O

          A label indicates the type of a vertex or an edge. For example, the label of a vertex can be "person" or "vehicle" and that of an edge can be "friend" or "family". A label describes the data formats of all properties about a vertex or an edge (defined in schema).


          • P

            A property is used to describe the information about a vertex or an edge in a graph.

          • S

            A schema is used to describe the property information about edges or vertices. A schema consists of multiple labels and each label consists of multiple properties.


            • U-Z

              Vertices represent entities in data models, such as vehicles in the traffic network, stations in the communications network, users and commodities in the e-commerce transaction network, and web pages on the Internet.
