Co-ownership Database System with Rule-Based Access Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud databases struggle to manage co-ownership among multiple members for data sharing, as traditional blockchain systems are inefficient in data migration and execution, failing to support multi-user shared database systems effectively.
Innovation Solution
A co-ownership database system is implemented, comprising an underlying database, a rule set defining member permissions, and a blockchain for storing operation history, where accessing requests are verified against the rule set to ensure secure and efficient data sharing among multiple members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional blockchain systems are used for co-ownership database management, then data sharing among multiple members is enabled, but execution efficiency and data migration capability deteriorate
Solution Approach 1:
The patent segments the database system into multiple independent nodes, each capable of autonomous operation and data storage. This segmentation allows the system to maintain blockchain's decentralized co-ownership capability while improving execution efficiency through parallel processing across nodes, directly resolving the contradiction between adaptability and productivity
2Adaptability or versatility
If traditional blockchain systems are used for co-ownership database management, then data sharing among multiple members is enabled, but data migration capability deteriorates
Solution Approach 1:
The patent implements a universal node architecture where each database node can perform multiple functions including data storage, computation, and seamless migration. This multi-functionality enables easy data migration between nodes while maintaining co-ownership capabilities, resolving the contradiction between adaptability and ease of manufacture
3Ease of operation
If existing cloud databases are used, then single-owner data management is achieved, but multi-member data sharing capability deteriorates
Solution Approach 1:
The patent transforms the static single-owner database model into a dynamic multi-owner system where ownership and permissions can be flexibly assigned and modified. The rule set dynamically adjusts access control based on member roles and operations, enabling both easy single-owner management and versatile multi-member sharing

AI summary
In implementations of the present disclosure, a solution for managing a co-ownership database system is provided. In this solution, multiple members access the database system as the co-owner thereof. The database system comprises: an underlying database for storing data of multiple members of the database system, a rule set defining constraints on operations of the multiple members over the database system, and a blockchain storing a record of an operation history of the database system. The database system is co-owned by the multiple members. In response to receiving a data accessing request from one of members, the accessing request will be verified based on the rule set. Subsequently, the accessing request will be processed according to a result of the verification.
