11 Graph Database Tables

12 Who uses Graph Tables?

13 GRAPH DATABASE TABLE TYPES NODE TABLES Represents Entities. A Column named $node_id created with every Node table. Recommended to create an index on the $node_id EDGE TABLES Represents Relationships. A Column named $edge_id created with every Edge table. Recommended to create an index on the $edge_id To create a relation you need to have two $node_id. $from_id $to_id

14 Available T-SQL extensions DDL DML Query CREATE TABLE ALTER TABLE CREATE INDEX DROP TABLE INSERT UPDATE DELETE SELECT MATCH

15 MATCH(graph_search_pattern) Specifies the pattern to search Pattern needs to go from one entity to another using a relationship Arrow character specifies the direction. Parenthesis remarks the relationships SELECT U.Name, W.CreatedDT, P.ProductId, P.Brand, P.ProductName FROM Products P, Wished W, Users U WHERE MATCH(U-(W)->P) and U.UserId = 1
