Database

Overview​

The Database Element is used to store key-value (KV) format data, handling common application scenarios swiftly. For more complex database usage scenarios, A Babel application can have multiple Database Elements, and you can select a specific Database Element when using or viewing.

Features​

Schema structure​

A Database Element is equivalent to a key-value (KV) database, where you can define the field names and field types for the value part.

Quota​

A single record in a Database Element can support up to 20KB, and each user is allocated 1GB of storage space.

Access​

Access in the Database SDK​

We provide a series of interfaces for the Database Element to manipulate data. Using the 'set' interface as an example, we will demonstrate how to insert a piece of data into the Database Element.

import { myDB } from '#elements';

...

myDB.set("David",{
  "name": "David",
  "actived": true,
  "age": 66,
  "hobbies":[
    "sing",
    "ai",
    "nature"
  ]
})

...

For more examples of the Database SDK, please refer to the Database SDK section.

Access in the Executor​

The Database Executor supports 'set', 'put', 'list', and 'delete' operations.

Please be aware that these operations directly manipulate the data of the Database Element. Exercise caution when using 'set' and 'delete' operations.

View data in the Dashboard​

Babel also provides a way to view the data of Database Elements within the Dashboard. By clicking the database button in the top right corner of the Workspace, you can access the Database Dashboard.
