Engineering Contradiction Analysis
1Adaptability or versatility
If compound keys are mapped component-by-component across different data processing systems, then adaptability between different identification schemes is improved, but mapping complexity and processing time increase
Solution Approach 1:
The compound key is segmented into individual components (e.g., agency identifier, scheme identifier, key value) that can be independently mapped. Each component is matched against corresponding components in the target identification scheme, allowing flexible adaptation across different data processing systems without requiring complete key structure matching.
Solution Approach 2:
A key mapping database serves as an intermediary between source and destination data processing systems. This database stores mapping relationships between compound keys from different identification schemes and resolves the complexity by providing a centralized translation layer that handles the adaptation between disparate key structures.
2Measurement precision
If complete compound keys are used for data identification, then identification precision is improved, but data processing efficiency decreases due to longer key lengths
Solution Approach 1:
The essential identifying components of the compound key are extracted and mapped to a simplified surrogate key format. By taking out only the necessary identifying elements and representing them in a compact form, the system maintains unambiguous identification while reducing key length and improving processing efficiency.
Solution Approach 2:
The key representation parameters are changed from a detailed compound structure (multiple components) to a condensed surrogate structure. This parameter transformation preserves the unique identification capability while optimizing for faster processing and reduced storage requirements through compact key representation.
