Read-Only Database Copy for Mobile Fleet Querying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributed databases, such as those in vehicle fleets, are costly and time-consuming to duplicate, and querying them directly can be risky due to resource constraints and unstable connectivity.
Innovation Solution
The system screens queries for feasibility and tailors them for different vehicle models by referencing databases of computational resources and running processes, ensuring resource efficiency and minimizing the risk of resource shortages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If distributed databases are duplicated to enable querying, then query accessibility is improved, but storage cost and time consumption increase
Solution Approach 1:
The patent creates a read-only duplicate copy of the distributed database specifically for querying purposes. This copy contains the same data as the original but is optimized for read operations, allowing multiple queries without affecting the original database structure or requiring full duplication of write capabilities.
Solution Approach 2:
The system separates the database into two distinct components: the original writable database and a read-only query duplicate. This segmentation allows each component to be optimized for its specific function, reducing the overhead of maintaining a full duplicate while enabling efficient querying operations.
2Reliability
If queries are directed to the original database, then data consistency is improved, but system stability deteriorates due to resource constraints
Solution Approach 1:
The patent divides database operations into two separate pathways: write operations continue to access the original database to maintain data consistency, while read operations are redirected to the read-only duplicate. This segmentation prevents query-induced resource contention that could destabilize the system.
Solution Approach 2:
The read-only duplicate acts as an intermediary between query requests and the original database. It absorbs the load of querying operations, preventing direct access to the original database and thereby maintaining system stability while still providing access to consistent data.
3Adaptability or versatility
If connectivity between products increases to enable new applications, then application versatility is improved, but data structure understanding complexity increases
Solution Approach 1:
The read-only duplicate provides a standardized interface for querying distributed database content across different products. By presenting a consistent data structure view in the duplicate, developers can build versatile applications without needing to understand the complex underlying data structures of each individual product.

AI summary
Mobile computing network programming for queried content capture is performed by receiving, from a client device, a query for a target content of data capturable by a fleet of mobile computing networks, the query including a target content identifier that identifies the target content, programming a task to capture the target content, the task programmed to be executed by each mobile computing network using available resources of the mobile computing network, transmitting the task to each mobile computing network; and receiving data including the target content from each mobile computing network among the fleet of mobile computing networks.
