Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual construction of multiple data flows is performed for delta load tasks, then data synchronization can be achieved, but labor intensity and error rate increase
Solution Approach 1:
The system automatically generates delta load data flows by evaluating the ETL task definition and metadata, enabling self-service automation that eliminates manual construction while maintaining data synchronization accuracy through systematic evaluation of source-target table structures and change indicators
Solution Approach 2:
The patent introduces an intermediary evaluation mechanism that analyzes ETL task definitions, source table structures, target table structures, and data change indicators to automatically generate appropriate delta load strategies, serving as a mediator between ETL task definition and delta load execution
2Productivity
If existing delta load techniques are used, then data updates can be processed, but automation is lacking and multiple data flows must be manually specified
Solution Approach 1:
The system performs self-service automation by automatically evaluating ETL task definitions and metadata to generate delta load data flows without requiring manual specification, thereby increasing both productivity through automation and the extent of automated task specification
Solution Approach 2:
The patent applies preliminary action by evaluating the ETL task definition, source table structure, target table structure, and data change indicators before generating the delta load strategy, ensuring that all necessary information is prepared in advance to enable automated execution
3Ease of operation
If ETL information is leveraged to automatically specify delta load tasks, then manual effort is reduced, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary evaluation module that systematically processes ETL task definitions and metadata through a structured evaluation framework, managing the complexity of automatic delta load generation by breaking it down into discrete evaluation steps based on source-target table structures and change indicators
Data Source
