Technical details of cross-database compatibility
DbRheo-CLI adopts an innovative plug-in architectural design to provide native support for three mainstream relational databases: PostgreSQL, MySQL and SQLite. Its core technology lies in the implementation of a unified database access abstraction layer , the bottom layer through a dedicated adapter to deal with the dialectal differences between different databases .
The architecture implementation consists of three key components: 1) Connection Manager, which unifies authentication and connection pooling for different databases; 2) SQL Dialect Converter, which converts standard SQL to database-specific syntax; and 3) Metadata Collector, which adapts the table structure querying methods of each system. This design makes it possible to add support for new databases by developing only the corresponding adapter modules, keeping the core functionality unchanged.
Specific compatibility performance includes: 1) complete support for PostgreSQL's JSONB, arrays and other advanced types; 2) adapting MySQL's storage engine features; 3) optimizing SQLite's file database operations. In the cross-database operation test, the tool can correctly handle common syntax differences above 90%.
The future roadmap shows that the development team is working on Oracle and SQL Server adapters, with full support for enterprise-class databases planned for the next major release. This extensibility is designed to make DbRheo-CLI a truly universal solution for database operations.
