Main activities orchestrator for the Laborious system.
|

This class combines functionality from multiple activity classes to provide

a unified interface for all workflow operations. It manages database connections,
|
|
MLFlow model interactions, data quality validation, and OPC server communications.
|
|
|
|
The class implements multiple inheritance to combine specialized functionality:
|
|
- Postgres: Database operations and data persistence
|
|
- MLFlow: Model inference and transformation operations
|
|
- Gates: Data quality validation and filtering mechanisms
|
|
- OPC: Real-time data export to OPC servers

Attributes:
|

postgres_config (dict): PostgreSQL connection configuration

mlflow_config (dict): MLFlow server configuration
|

opc_config (dict): OPC server configuration
