TigerGraph installation and use

TigerGraph is a fast and efficient Graph database that supports the storage and query of large-scale graph data. The following is an introduction to the installation and use of TigerGraph, including the installation process and examples of how to create data tables, insert, modify, query, and delete data. Installation process: 1. Download the TigerGraph installation package. You can download the latest version of the TigerGraph installation package from the official TigerGraph website. 2. Unzip the installation package. Extract the downloaded installation package to the specified directory. Create a data table: 1. Start the TigerGraph service. Enter the TigerGraph installation directory and run the following command to start the TigerGraph service: ./bin/gadmin start all 2. Create a diagram architecture. Create a graph architecture using TigerGraph's GSQL language. Create a new. gsql file, such as mygraph.gsql, and save the following example code to the file: CREATE GRAPH mygraph #Declare vertex types CREATE VERTEX Person (PRIMARY_ID id INT, name STRING) #Declare edge type CREATE DIRECTED EDGE Follow (FROM Person, TO Person) 3. Import the diagram architecture. Run the following command in the terminal to import the graph architecture: ./bin/gsql < mygraph.gsql 4. Startup diagram. Run the following command to start the Graph database: ./bin/gsql gsql> START mygraph Data insertion, modification, query, and deletion: 1. Insert data. Insert data using GSQL language. Open a new. gsql file, such as mydata.gsql, and save the following example code to the file: USE GRAPH mygraph #Insert Vertex INSERT INTO Person (PRIMARY_ID, name) VALUES (1, "John") INSERT INTO Person (PRIMARY_ID, name) VALUES (2, "Alice") #Insert Edge INSERT INTO Follow VALUES ((SELECT id FROM Person WHERE name == "John"), (SELECT id FROM Person WHERE name == "Alice")) Run the following command to insert data: ./bin/gsql < mydata.gsql 2. Modify data. Modify data using GSQL language. Open a new. gsql file, such as myupdate. gsql, and save the following example code to the file: USE GRAPH mygraph #Modifying Vertex Properties UPDATE Person SET name = "John Smith" WHERE PRIMARY_ID == 1 #Modifying Edge Properties UPDATE Follow SET property = value WHERE FROM.id == 1 AND TO.id == 2 Run the following command to modify data: ./bin/gsql < myupdate.gsql 3. Query data. Use GSQL language to query data. Open a new. gsql file, such as myquery.gsql, and save the following example code to the file: USE GRAPH mygraph #Query Vertex SELECT * FROM Person #Query Edge SELECT * FROM Follow WHERE FROM.id == 1 Run the following command to query data: ./bin/gsql < myquery.gsql 4. Delete data. Delete data using GSQL language. Open a new. gsql file, such as mydelete.gsql, and save the following example code to the file: USE GRAPH mygraph #Delete Vertex DELETE FROM Person WHERE PRIMARY_ID == 1 #Delete Edge DELETE FROM Follow WHERE FROM.id == 1 AND TO.id == 2 Run the following command to delete data: ./bin/gsql < mydelete.gsql This completes the installation and use of the TigerGraph database. You can create data tables, insert, modify, query, and delete data according to your own needs. Please note that this is only a basic introduction to the use of TigerGraph.
