This commit implements multi-database support, allowing the system to switch
between SQL Server and MySQL databases seamlessly.
## New Features
- Database type selection (SQL Server or MySQL) via configuration
- Automatic table name conversion between formats ([dbo].[table] → dbo_table)
- Automatic parameter placeholder handling (? for SQL Server, %s for MySQL)
- GUI settings tab now includes database type dropdown and MySQL configuration
## Database Abstraction Layer
- db/base_connection.py: Abstract base class for database connections
- db/sqlserver_connection.py: SQL Server implementation
- db/mysql_connection.py: MySQL implementation using mysql-connector-python
- db/connection_factory.py: Factory pattern for creating connections
- db/table_name_converter.py: Table name format conversion utility
## DAO Base Class
- db/base_dao.py: Base DAO with helper methods for SQL conversion and placeholders
## Updated Components
- config/schema.py: Extended with DatabaseType enum and MySQL/SQLServer config classes
- config/defaults.py: Added MySQL default configuration
- config/loader.py: Updated to handle new database structure
- db/connection.py: Refactored to use factory pattern and load user config
- All DAO files: Updated to inherit from BaseDAO with automatic conversion
## Dependencies
- Added mysql-connector-python>=8.0.0 to requirements.txt
## Configuration
To use MySQL, set db_type to "mysql" in config/user_settings.json:
{
"database": {
"db_type": "mysql",
"mysql": {
"host": "192.168.31.83",
"port": 3306,
"database": "BLD_DB",
"username": "remote_user",
"password": "3.1415926Beeke"
}
}
}
