Distributed Database Segregation for Avionics Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Avionics systems face challenges in meeting disparate data requirements for security, integrity, and latency due to the inflexibility of fixed database architectures, which can be cost-prohibitive and fail to accommodate varying client application needs effectively.
Innovation Solution
A system and method that instantiates multiple databases with different performance attributes, allowing it to determine and meet specific data access requirements by routing requests to the appropriate databases, potentially submitting requests to two or more databases for increased integrity and comparing results for robust checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed database architecture is used, then system simplicity is maintained, but flexibility to meet disparate data requirements deteriorates
Solution Approach 1:
The patent segments the database architecture into multiple independent database instances, each optimized for specific performance attributes (security, integrity, latency). This allows the system to meet disparate data requirements by routing queries to appropriate segmented databases rather than using a monolithic fixed architecture.
Solution Approach 2:
The patent implements a universal database access layer that handles multiple types of data access requests (security-critical, integrity-critical, latency-critical) through a single interface. This multi-functional access layer routes requests to different database instances based on requirements, providing flexibility without increasing client-side complexity.
2Adaptability or versatility
If multiple databases with different performance attributes are instantiated, then ability to meet disparate requirements improves, but system complexity increases
Solution Approach 1:
The patent introduces a database access layer as an intermediary between client applications and multiple database instances. This mediator handles the complexity of routing requests to appropriate databases based on performance requirements, shielding clients from the underlying database infrastructure complexity while enabling flexible requirement fulfillment.
3Reliability
If strict requirements in one metric are accommodated, then data security or integrity is improved, but cost becomes prohibitive
Solution Approach 1:
The patent applies local quality by instantiating multiple databases with different performance attributes and routing queries to appropriate databases based on specific requirements. This allows the system to allocate resources efficiently - using high-cost databases only when strict security or integrity requirements are needed, rather than uniformly applying high-cost infrastructure across all data access operations.
Data Source
AI summary
A system and method for accessing data to meet disparate security, integrity, and latency requirements includes multiple databases instantiated in the system with different performance attributes. The system receives a data access request from a client application. The system determines one or more data access requirements associated with the data access request and identify a database or set of databases that conform to those requirements. The system then submits the data access request to the identified databases and returns the result to the client application. The system may determine a data integrity threshold for the data access request, and submit the data access request to two or more databases simultaneously.
