Functions

Data Admin Service (DAS) provides the following functions:

Development Tool

  • It is an easy-to-use database client designed for for developers.
  • You do not need to install a local client. Diverse database development functions are available, including data and table structure synchronization, online editing, and intelligent prompts for SQL input.
  • DAS provides common development functions such as database visualized windows and database and table management, meeting management requirements for multiple database types, such as RDS for MySQL, RDS for SQL Server, RDS for PostgreSQL, DDS, TaurusDB, and GaussDB. The database management objects consist of tables, views, stored procedures, events, triggers, and functions.
    1. Tables: MySQL data tables consist of basic information, field or column details, virtual columns, indexes, and foreign keys. The virtual columns, indexes, and foreign keys are optional. You can directly perform operations on tables in a database.
    2. Views are a mapping of one or more tables and are used only for query.
    3. Events are time triggers, which can complete specific operations at a specific time.
    4. Stored procedures are a set of SQL statements for performing specific functions. They usually exist in databases. You only need to modify the corresponding parameters to implement a specific transaction.
    5. Triggers are SQL statements that are automatically executed to perform operations on another associated table before or after an operation (addition, deletion, or modification) is performed on a table. Triggers are used to enhance data integrity constraints and atomic event rules.
    6. Functions include system functions and user-defined functions. You can set different functions to reuse a function.

Intelligent O&M

Database O&M functions for DBAs:
  • Host and instance performance data analysis
  • Slow and all query logs analysis
  • Real-time database performance diagnosis and analysis
  • Database historical running data analysis
Intelligent O&M is implemented through the following intelligent charts:
  • Performance
  • Real-time diagnosis
  • Performance trend comparison
  • User-defined graphs
  • Real-time sessions
  • Urgent session killing
  • Slow query logs
  • SQL Explorer
  • SQL diagnosis
  • SQL throttling
  • InnoDB locks
  • Metadata locks
  • Daily reports
  • Storage analysis
  • Anomaly snapshots

Billing

  • Billing Mode

    Intelligent O&M supports both free and paid instances. The difference lies in the SQL data storage duration. For free instances, SQL data is stored for one hour. For details about the SQL data storage duration of billed instances, see Billing Policy. This billing rule applies to both existing and new instances using Intelligent O&M. You can enable Slow Query Logs and SQL Explorer for up to 10 free instances. There is no such a limit on paid instances. For details, see Intelligent O&M Pricing Details.

  • Billing Items

    Intelligent O&M billing items include basic (only for paid instances) and additional fees for extra storage.

    • Basic fees are calculated by the hour. Usage of less than 1 hour will be rounded up.
    • Additional fees: If your data exceeds the free 5 GB limit for 30 days of storage, DAS will allocate more resources and bill you for the extra usage.
