+## Core Features
+**Secure Access**
+- **Account and Password Security Management**：Safely manage database account passwords without manual maintenance, effectively preventing sensitive information leakage.
+- **Fine-grained Permission Control**：Supports instance, database, table, field, and row-level access control, precisely restricting caller permissions to prevent unauthorized operations and ensure data security.
+- **High-risk SQL Identification and Blocking**: Built-in rich rule engine that identifies and blocks potential high-risk SQL in real time to mitigate security risks.
+- **SQL Audit Trail**: Records all SQL operation logs, supporting full traceability and compliance audits to meet regulatory requirements.

-## Core Features
-Provides AI with a unified **data access layer** and **metadata access layer**, solving through standardized interfaces:
-- Maintenance costs caused by data source fragmentation
-- Compatibility issues between heterogeneous protocols
-- Security risks from uncontrolled account permissions and non-auditable operations
-
-Key features via MCP include:
-- **NL2SQL**: Execute SQL via natural language to obtain data results
-- **Code Generation**: Retrieve schema information through this service to generate DAO code or perform structural analysis
-- **Data Retrieval**: Automatically route SQL to accurate data sources for business support
-- **Security**: Fine-grained access control and auditability
-- **Data Migration**: Configure data migration tasks

+#### Scenario Example 2:
+You are a data analyst at an e-commerce company, needing to frequently query and analyze business data such as orders, users, and products. The company's core business database is located at ecommerce@10.20.30.40:3306.

+Simply ask questions in natural language, and DMS MCP will parse the question into SQL and return the results.
+
+**Typical Question Examples:**
+- What is the total number of orders today?
+- How are the order counts ranked by province?
+- What is the number of new users each day over the past 7 days?
+- Which product category has the highest sales revenue?
