Create a schema¶

To batch import data into Nebula Graph, you must have a graph schema. You can create a schema on the Console page or on the Schema page of Studio.

](https://docs.nebula-graph.io/2.0/2.quick-start/3.connect-to-nebula-graph/) and Get started with Nebula Graph.

Prerequisites¶

To create a graph schema on Studio v2.x, you must do a check of these:

• Studio is connected to Nebula Graph v2.x.

• Your account has the privilege of GOD, ADMIN, or DBA.

• The schema is designed.

• A graph space is created. !!! note

  If no graph space exists and your account has the GOD privilege, you can create a graph space on the **Console** page. For more information, see [CREATE SPACE](../../3.ngql-guide/9.space-statements/1.create-space.md). In this example, we recommend that you set `vid_type=FIXED_STRING(100)` in the `CREATE SPACE` statement.
  

Create a schema with Schema¶

To create a schema on the Schema page, follow these steps:

1. Create tags. For more information, see Operate tags.

2. Create edge types. For more information, see Operate edge types.

Create a schema with Console¶

To create a schema on the Console page, follow these steps:

1. In the toolbar, click the Console tab.

2. In the Current Graph Space field, choose a graph space name. In this example, mooc_actions is used.

   

3. In the input box, enter these statements one by one and click the button .

   // To create a tag named "user", with no property
   nebula> CREATE TAG user ();
   
   // To create a tag named "course", with one property
   nebula> CREATE TAG course (courseId int);
   
   // To create an edge type named "action", with seven properties
   nebula> CREATE EDGE action (actionId int, duration double, label bool, feature0 double, feature1 double, feature2 double, feature3 double);
   

If the preceding statements are executed successfully, the schema is created. You can run the statements as follows to view the schema.

// To list all the tags in the current graph space
nebula> SHOW TAGS;

// To list all the edge types in the current graph space
nebula> SHOW EDGES;

// To view the definition of the tags and edge types
nebula> DESCRIBE TAG user;
nebula> DESCRIBE TAG course;
nebula> DESCRIBE EDGE action;

If the schema is created successfully, in the result window, you can see the definition of the tags and edge types.

Next to do¶

When a schema is created, you can import data.
