For DBA and O&M
Improve Development Efficiency
DAS provides a best-in-class experience. Developers no longer need to install clients for a visualized experience. Diverse database development functions are available, including data and table structure synchronization, online editing, and intelligent prompts for SQL input.
Advantages
Intelligent prompts when inputting SQL statements.
Quick reuse of history SQL statements.
Support for visualized table structure editing.
Support for adding, editing, or deleting the data in your tables. Complex manual SQL input is no longer needed.
Enable DBA and O&M
DAS offers a wide range of functions, covering instance performance data, slow SQL analysis, SQL explorer, real-time performance analysis and diagnosis, as well as analysis of historical operations, so you can quickly locate any issue occurring during database operations and prevent issues from arising in the future.
Advantages
Slow SQL statistics are correlated with historical CPU loads so it is easier to determine which statements are creating the issues.
Slow SQL statements can be summarized into templates and sorted out by execution count, time, and lock wait so you can quickly discover the most problematic SQL statements.
Automatic diagnosis on slow SQL statements offers index optimization and SQL rewriting suggestions, assisting in SQL tuning.
Real-time sessions and slow SQL statements are displayed in a list. Sessions can be killed in just a few clicks.
All aspects of database instance performance and current status are graphically represented so you can find faults fast.
In addition to the historical performance data, you can compare performance data from specific time periods or define custom metrics for multi-dimensional analysis, facilitating quick fault location and recovery.

Intelligent SQL Diagnosis and Tuning
Batch diagnosis of SQL files and diagnosis of complex SQL statements such as multi-table JOIN statements or nested subqueries offer tuning suggestions and help you quickly detect slow SQL statements.Batch diagnosis of SQL files and diagnosis of complex SQL statements such as multi-table JOIN statements or nested subqueries offer tuning suggestions and help you quickly detect slow SQL statements. -
Emergency Channel
Instance suspension is no longer a threat. If an instance connection count reaches a predefined limit, unnecessary connections can be killed to shorten the fault time.Instance suspension is no longer a threat.
