Source Independent Query Language for Unified Data Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data validation systems require duplicative efforts across client-side, server-side, and database tiers, leading to increased development, testing, and maintenance costs due to the need for separate validation processes on user interfaces, client data, and database-stored data, often resulting in inefficiencies and potential data integrity issues.
Innovation Solution
A system that enables a single SQL query to be executed against both in-memory data and database-stored data, using a query processor to generate a derived table from user interface data and convert it into a format executable by a relational database, allowing for unified data validation without requiring separate programs for each tier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate validation processes are implemented for user interface, client data, and database tiers, then data validation can be performed at each layer, but development, testing, and maintenance costs increase due to duplicative efforts
Solution Approach 1:
The patent implements a universal validation framework that can operate across multiple tiers (user interface, client, database) using the same validation logic. The system allows a single validation program to serve multiple purposes: validating user interface inputs, validating client data, and validating database-stored data, thereby eliminating the need for separate validation processes at each layer while maintaining comprehensive data validation coverage
Solution Approach 2:
The patent merges previously separate validation processes into a unified validation framework. By combining client-side validation, server-side validation, and database validation into a single integrated system, the patent reduces duplicative code, simplifies maintenance, and lowers overall system complexity while preserving the reliability benefits of multi-layer validation
2Reliability
If separate validation programs are written for each tier, then validation can be optimized for specific platform requirements, but development and maintenance costs increase
Solution Approach 1:
The patent creates a universal validation program that can be deployed across different tiers (user interface, client, database) without requiring separate implementations. This single validation program can validate data at any tier while adapting to platform-specific requirements through configuration rather than code modification, thereby reducing development costs while maintaining validation reliability
Solution Approach 2:
The patent segments the validation system into modular components that can be independently configured for different tiers. This segmentation allows the same core validation logic to be reused across user interface, client, and database layers, reducing the need to write separate validation programs for each tier while still optimizing for platform-specific requirements through configurable parameters
3Reliability
If validation is performed only at the database tier, then database data integrity is maintained, but user interface and client data may not be validated
Solution Approach 1:
The patent implements a universal validation framework that can be applied at multiple tiers simultaneously. The same validation logic can validate user interface inputs before they reach the client, validate client data before it reaches the database, and validate database-stored data to maintain integrity. This multi-tier validation coverage ensures both data integrity and comprehensive validation without requiring separate specialized systems
4Reliability
If multiple validation programs are maintained, then each validation can be optimized for its specific tier, but maintenance costs and overhead increase
Solution Approach 1:
The patent maintains a single universal validation program that can operate at user interface, client, and database tiers. This eliminates the need to maintain multiple separate validation programs, significantly reducing maintenance time and overhead. The unified program preserves validation effectiveness by allowing the same validation logic to be applied across all tiers, ensuring consistency and reducing the cumulative maintenance burden
