輸入gsql命令
[tiger@ ~]$ gsql
目前圖數據庫是空的
GSQL-Dev > ls
---- Global vertices, edges, and all graphs
Vertex Types:
- VERTEX user(PRIMARY_ID id STRING, fans_num INT) WITH STATS="OUTDEGREE_BY_EDGETYPE", PRIMARY_ID_AS_ATTRIBUTE="false"
Edge Types:
Graphs:
- Graph MyGraph(user:v)
Jobs:
JSON API version: v2
Syntax version: v1
創建一個person用戶節點類型：
GSQL-Dev > CREATE VERTEX person (PRIMARY_ID name STRING, name STRING, age INT, gender STRING, state STRING)
The vertex type person is created.
當然也可以用GraphStudio，更加方便，輸入IP地址：14240，便可訪問GraphStudio，創建。
可以看到界面只需要用Button就可以創建例如一個User的節點類型。
創建邊類型：
The vertex type person is created.
GSQL-Dev > CREATE UNDIRECTED EDGE friendship (FROM person, TO person, connect_day DATETIME)
The edge type friendship is created.
This feature is not supported in the developer edition.
See doc.tigergraph.com for a comparison of the editions.
ls發現已經有圖存在了，tigergraph不好的一點就是社區版只能支持一張圖，但是如果這張圖巨大，還是比較合適應用的。
所以只能先把這一切刪除了
GSQL-Dev > drop all
Dropping all, about 1 minute ...
Abort all active loading jobs

[ABORT_SUCCESS] No active Loading Job to abort.

Graph store /home/tigergraph/tigergraph/gstore/0/ has been cleared!
Everything is dropped.
再重新創建：可以發現已經創建了一個叫social的圖，包含點person和邊friendship
GSQL-Dev > ls
---- Graph social
Vertex Types:
- VERTEX person(PRIMARY_ID name STRING, name STRING, age INT, gender STRING, state STRING) WITH STATS="OUTDEGREE_BY_EDGETYPE"
Edge Types:
- UNDIRECTED EDGE friendship(FROM person, TO person, connect_day DATETIME)
Graphs:
- Graph social(person:v, friendship:e)

Queries:
上傳數據
GSQL-Dev > USE GRAPH social

The job load_social is created.
運行Job

[Tip: Use "CTRL + C" to stop displaying the loading status update, then use "SHOW LOADING STATUS jobid" to track the loading progress again]
[Tip: Manage loading jobs with "ABORT/RESUME LOADING JOB jobid"]

從GraphStudio可以看到，可視化做得有點渣渣
