Multi-tier Distributed System Transaction Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-tier distributed systems face challenges in enhancing the independence of tiers, requiring large storage for long transactions and complicating data management due to the need for inter-tier processing, which hinders efficient operation.
Innovation Solution
A multi-tier distributed system is designed with monitoring and communication mechanisms between upper and lower nodes, allowing for independent execution of transactions across tiers, including version management and dynamic node updating, to enhance tier independence and simplify data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If processing of one tier is inserted into processing of another tier to guarantee atomicity, then transaction atomicity is improved, but independence of each tier deteriorates
Solution Approach 1:
The patent segments the distributed transaction processing into independent tier-level transactions, where each tier processes its own transaction independently. The upper tier executes its transaction and the lower tier executes its transaction separately, with each having its own transaction management. This segmentation allows each tier to maintain independence while still achieving overall atomicity through the coordination mechanism.
2Quantity of substance
If one transaction takes a long time, then storage capacity required is improved, but management and maintenance difficulty increases
Solution Approach 1:
The patent divides a long-running distributed transaction into multiple shorter tier-level transactions that execute independently at different tiers. Instead of holding all resources in memory for the entire duration of a long transaction, each tier processes and commits its transaction separately, reducing the storage burden and improving manageability.
3Reliability
If inter-tier processing is required to ensure transaction consistency, then transaction consistency is improved, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the upper node monitors the running status of the lower node through monitoring means. The lower node includes monitor enabling means that allow the upper node to monitor its status. Based on this feedback, the system can dynamically adjust transaction execution, ensuring consistency while managing complexity through intelligent coordination rather than rigid inter-tier processing.

AI summary
The independencies of a plurality of layers executing dividingly a transaction can be easily enhanced. Anode (30) assigns to a transaction to anode (30) of a lower layer through a distributed transaction management section. The node (30) shares a predetermined transaction with the node (30) of the lower layer along with other nodes (30). The node (30) shared by the nodes (30) is a read-only node or a node to which data can be written by the characteristic of a function. Thus the node (30) searches for an unused node (30) in lower layers through the distributed transaction management section (34) when the node starts a new transaction. First, second, and third node hosts (3,4,5) check if each node (30) is used for which transaction or if each node (30) is used or not and store the results.
