Overview

You can go to the Database Management page using either of the following methods:

  • In the database list of the Home page, locate the target database and click Manage in the Operation column.
  • Select Database Management on the top menu bar.

Schemas

    • Open: Click it to display the table name, row value, and character set of the corresponding database schema.
    • Drop: Click it to drop a schema. A dropped schema cannot be restored. Exercise caution when performing this operation.

Objects

You can create objects such as tables, views, and triggers by executing SQL statements.

Metadata Collection

DAS periodically collects DB instance metadata of databases, tables, and fields and stores the collected data in the DAS database. In addition, it collects only structural metadata, but not data in user tables, which ensures data security. Metadata collection delivers the following advantages:

  • Reduces queries on user databases and the impact on the performance of user databases.
  • Improves the search performance for DB instances that contain a large number of tables and supports pagination queries.

Procedure

  1. On the Database Management page, enable Auto Metadata Collection in the upper right corner and click the Metadata Collection tab.
  2. On the displayed page, click Collect Now to start the collection. You can also stop the collection or view collection details.

    • Clear Collected Data: Clears the collected data such as metadata, database structure, and table structure.
    • Delete Logs: Deletes logs. Deleted logs cannot be restored.
