Data Admin Service (DAS)

Description

Data Admin Service (DAS) is a one-stop platform that allows you to manage databases on a web console. It offers database development, O&M, and intelligent diagnosis, making it easy for you to use and maintain databases. The Standard Edition provides a best-in-class experience. You no longer need to install clients locally for a visualized operation experience. Diverse database development functions are available, including data and table structure synchronization, online editing, and intelligent prompts for SQL input.

Version Requirements: The GaussDB(DWS) version must be 8.0.1 or later, and the Agent version must be 8.1.3.101 or later.

DAS provides the following functions for GaussDB(DWS) developers:

Browsing and managing database objects, such as databases, tables, views, stored procedures, sequences, and triggers.
Editing and executing PL/SQL statements
Managing SQL execution records
