OrientDB provides a web UI to carry out database operations through GUI. This chapter explains the different options available in OrientDB.

Studio Homepage

Studio is a web interface for the administration of OrientDB that comes in bundle with the OrientDB distribution.

First, you need to start the OrientDB server using the following command.

$ server.sh 

If you run OrientDB in your machine, the web interface can be accessed via the URL −

http://localhost:2480

If the command is executed successfully, following will be the output on screen.

Connect to an Existing Database

To login, select a database from the databases list and use any database user. By default (username/password) reader/reader can read records from the database, writer/writer can read, create, update and delete records, while admin/admin has all rights.

Drop an Existing Database

Select a database from the databases list and click the trash icon. Studio will open a confirmation popup where you have to insert the Server User and Server Password.

Then click the “Drop database” button. You can find the server credentials in the $ORIENTDB_HOME/config/orientdb-server-config.xml file.

<users> 
   <user name = "root" password = "pwd" resources = "*" /> 
</users>

Create a New Database

To create a new database, click the “New DB” button from the homepage.

Following information is needed to create a new database −

• Database name
• Database type (Document/Graph)
• Storage type (plocal/memory)
• Server user
• Server password

You can find the server credentials in the $ORIENTDB_HOME/config/orientdbserver-config.xml file.

<users> 
   <user name = "root" password = "pwd" resources = "*" /> 
</users>

Once created, Studio will automatically login to the new database.

Execute a Query

Studio supports auto recognition of the language you”re using between those supported: SQL and Gremlin. While writing, use the auto-complete feature by pressing Ctrl + Space.

The following shortcuts are available in the query editor −

• Ctrl + Return − To execute the query or just click the Run button.

• Ctrl/Cmd + Z − To undo changes.

• Ctrl/Cmd + Shift + Z − To redo changes.

• Ctrl/Cmd + F − To search in the editor.

• Ctrl/Cmd + / − To toggle a comment.

The following screenshot shows how to execute a query.

By clicking any @rid value in the result-set, you will go into document edit mode if the record is a Document, otherwise you will go into vertex edit.

You can bookmark your queries by clicking the star icon in the results-set or in the editor. To browse bookmarked queries, click the Bookmarks button. Studio will open the bookmarks list on the left, where you can edit/delete or rerun queries.

Studio saves the executed queries in the Local Storage of the browser. In the query settings, you can configure how many queries studio will keep in history. You can also search a previously executed query, delete all the queries from the history, or delete a single query.

Edit Vertex

To edit the vertex of the graph, go to the Graph section. Then run the following query.

Select From Customer

On successfully running the query, following be the output screenshot. Select the particular vertex in the graph canvas to edit.

Select the edit symbol on the particular vertex. You will get the following screen which contains the options to edit the vertex.
