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.

Schema Manager

OrientDB can work in schema-less mode, schema mode or a mix of both. Here we’ll discuss the schema mode. Click on the Schema section on the top of web UI. You will get the following screenshot.

Create a New Class

To create a new Class, just click the New Class button. Following screenshot will appear. You will have to provide the following information as shown in the screenshot to create the new class.

View All Indexes

When you want to have an overview of all indexes created in your database, just click he all indexes button in the Schema UI. This will provide a quick access to some information about indexes (name, type, properties, etc.) and you can drop or rebuild them from here.

Edit Class

Click on any class on the schema section, you will get the following screenshot.

While editing a class, you can add a property or add a new index.

Add a Property

Click the New Property button to add property. You will get the following screenshot.

You have to provide the following details as shown in the screenshot to add property.

Add an Index

Graph Editor

Click the graph section. Not only can you visualize your data in a graph style but you can also interact with the graph and modify it.

To populate the graph area, type a query in the query editor or use the functionality Send To Graph from the Browse UI.

Add Vertices

To add a new Vertex in your Graph Database and in the Graph Canvas area, you have to press the button Add Vertex. This operation is done in two steps.

In the first step, you have to choose the class for the new Vertex and then click Next.

In the second step, you have to insert the field values of the new vertex. You can also add custom fields as OrientDB supports schema-less mode. To make the new vertex persistent, click ‘Save changes’ and the vertex will be saved into the database and added to the canvas area.

Delete Vertices

Open the circular menu by clicking on the Vertex that you want to delete. Open the submenu by hovering the mouse to the menu entry more (…) and then click the trash icon.

Remove Vertices from Canvas

Open the circular menu, open the sub-menu by hovering the mouse to the menu entry more (…) and then click the eraser icon.

Inspect Vertices

If you want to take a quick look to the Vertex property, click to the eye icon.
