Database Multicast Query Distribution for Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional relational database systems face challenges in processing efficiency and reliability, particularly when handling complex queries and large datasets, as they often require redistributing data across multiple storage devices, leading to potential bottlenecks and single-point failures.
Innovation Solution
A database system utilizing a master node that communicates multicast signals over multiple communication channels to distribute pre-compiled queries across a network of slave nodes, allowing each node to access and process key parts, thereby enhancing processing efficiency and redundancy.

Engineering Contradiction Analysis
1Reliability
If data is distributed across multiple storage devices to improve reliability, then system reliability improves, but data redistribution complexity and processing time increase
Solution Approach 1:
The patent applies preliminary action by pre-compiling queries and pre-distributing data to slave nodes before actual query execution. The master node sends multicast signals with pre-processed query information to multiple slave nodes in advance, so that when a query arrives, the system can immediately retrieve and process the pre-positioned data without requiring time-consuming redistribution operations.
Solution Approach 2:
The patent segments the database system into a master node and multiple slave nodes, with data divided into key parts distributed across different slave nodes. This segmentation allows parallel processing of queries across multiple nodes simultaneously, reducing the overall time required while maintaining data redundancy for reliability.
2Productivity
If data is redistributed to process complex queries, then query processing capability improves, but system complexity increases
Solution Approach 1:
The patent merges multiple slave nodes into a coordinated network under a single master node, which manages query distribution using multicast signals. This merging approach allows the system to process complex queries by distributing them across multiple nodes simultaneously, improving productivity while the master node abstracts away the complexity of coordination from the user.
Solution Approach 2:
The master node acts as an intermediary between the query source and the slave nodes storing data. It receives queries, processes them using multicast signals to distribute to appropriate slave nodes, and aggregates results. This intermediary role simplifies the system architecture by centralizing coordination logic while enabling parallel processing across distributed nodes.
3Productivity
If multiple communication channels are used for multicast signals, then processing efficiency improves, but network complexity increases
Solution Approach 1:
The patent implements multi-functionality by having slave nodes capable of receiving and processing multicast signals on multiple communication channels. Each slave node can monitor multiple channels and respond to queries based on the channel it receives on, allowing the system to achieve parallel processing efficiency while using standardized multi-channel communication protocols that manage network complexity through established conventions.

AI summary
A database system for processing a query includes at least one master node that is operable to communicate a multicast signal over a plurality of communication channels. The multicast signal includes a request to perform an action associated with a pre-compiled query. In one particular embodiment, the at least one master node communicates the multicast signal over a first communication channel. The system also includes a plurality of slave nodes that are coupled to the at least one master node. Each of the plurality of slave nodes is operable to receive the multicast signal from the first communication channel. In this particular embodiment, at least one of the plurality of slave nodes provides access to at least one key part that is also accessible through another one of the plurality of slave nodes.
