Efficiency optimization solutions for cross-database analysis
For scenarios where multiple databases (e.g. Postgres, MySQL, etc.) need to be handled at the same time, DataLine provides a unified and standardized solution for the operation interface. It can be realized in three steps:
- Unified Connection ManagementCreate multiple data source profiles in DataLine, support connection parameter presets for Postgres/MySQL/Snowflake databases, and verify the correctness of the configuration through the 'Test Connection' function.
- Intelligent SQL Conversion: Use DataLine's natural language interface when writing queries, and the system will automatically adapt to the SQL dialects of different databases. For example, if you input "extract order data in the last three months", it will generate DATE_SUB syntax for MySQL and INTERVAL syntax for Postgres.
- Centralized visualization: Data from different sources can be correlated and analyzed through the "Merge Data Sets" function, which supports the generation of cross-database comparison charts. The system automatically handles differences in time zones, field types, etc.
It is recommended to standardize the environment with Docker deployment to avoid compatibility problems caused by different database drivers. For high-frequency use of cross-database queries, you can save as a template and set a timer to refresh.
