首先我们需要定义一张Hive点表和Hive边表, 表里面指定schema信息以及metastore uri等信息: set geaflow.dsl.window.size = -1; CREATE TABLE IF NOT EXISTS hive_person ( id BIGINT, name VARCHAR ) WITH ( type='hive', geaflow.dsl.hive.database.name = 'default', geaflow.dsl.hive.table.name =...

Your user’s graph visualization relies on a small proportion of what’s in the database, but we can use visual modeling to simplify it further. This visualization shows graph data relating to car insurance claims. Our schema includes car and policyholders, phone numbers, insurance claims, ...
node type (labels) node schema: attributes 组成了schema. 同样的, Edge也有 Edge Type 和Edge Schema 如果是一个完整的图,会包含以下信息 weight 权重,比如两点之间的 距离 1. Path Analytics 一些定义: walk - 图上随便走的轨迹 path - 没有中间node重复的walk,比如 A-B-C-D-B-E 这个属于walk 不属于...

A view fetches many types of data, but a subquery fetches a single type of object. Translated into SQL, these subqueries take the form SELECT columns FROM table WHERE condition without any joins. The conditions represent the relation between objects which was defined in the schema. LiveGraph ...
. The semantic graph database paradigm uses ontological systems for typing schema: large, labeled, directed graphs for data; graph pattern matching for query; and recursive query languages for graph analysis. They are especially useful when it comes to highly complex and particularly large da...

Direct views of your graph data but requires (technical) Cypher knowledge Great for rapid query development Neo4j Browser is great for one-off tasks like database querying, schema exploration, and quick data validation. While it lacks advanced styling and isn’t a reporting tool, it’s a good...
OrientDB 对于数据模式的支持相对灵活,可以管理无模式数据 (schema-less),也可以像关系数据库那样定义完整的模式(schema-full),还可以适应介于两者之间的混合模式(schema-mixed) 数据。在查询语言方面,OrientDB 支持扩展的 SQL 和 Gremlin 用于图上的导航式查询;OrientDB 的 MATCH 语句实现了声明式的模式匹配,这类似...
