3. the graph database stores Entities representing by Node,relationships between entities explained with Edge and Property attached with Nodes and edges.
4. the data model of NebulaGraph includes 6 basical data type such as Space,Vertex,Edge,Tag, Edge,Property.

• the various project datas is stored on different graph spaces are to be separated with them.
• a vertex can be indicated by VIDs that each one of them is unique.
• Edge which has direction makes a link with two vertexs ,is indentified by<start VID、Edge type、rank、end VID> exclusively.one edge has only one Edge type and only one rank.
