Pre-Scheduled Data Decompression for Faster Multi-Stage Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data management systems face inefficiencies in accessing compressed data, leading to slower data retrieval times when decompression occurs after the data reference process has started, which can result in increased server usage costs and reduced performance.
Innovation Solution
A data management system that includes a process reception processing unit for compressing data and storing it in a compressed database, with a decompression processing unit that decompresses data at a predefined time before an acquisition process begins, allowing for faster data access and reduced server usage by anticipating and preparing decompressed data in advance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data is compressed and stored in a compressed database, then storage efficiency is improved, but data access speed deteriorates when decompression is needed
Solution Approach 1:
The system performs preliminary decompression of compressed data before the acquisition process starts. The decompression processing unit decompresses data at a predefined time before an acquisition process is started, so that when data is needed, it is already in decompressed form and can be accessed immediately without waiting for decompression during the acquisition process.
2Use of energy by moving object
If decompression is performed after acquisition process starts, then system resource usage is reduced, but processing time increases
Solution Approach 1:
Decompression is performed in advance at a predefined time before the acquisition process starts, rather than during or after the acquisition process. This preliminary action ensures that decompressed data is ready when needed, eliminating delays in the acquisition process while allowing the system to manage resources efficiently by controlling when decompression occurs.
3Speed
If data is kept in decompressed form, then data access speed is improved, but storage space consumption increases
Solution Approach 1:
The system maintains compressed data in the compressed database and only decompresses data preliminarily at a predefined time before acquisition is needed. This approach allows the system to have decompressed data ready for fast access when required, while otherwise maintaining storage efficiency through compression, thus balancing storage space consumption with data access speed requirements.

AI summary
A data management system includes a process reception processing unit that receives input of data in each of processes in plural stages of an item, a compression processing unit that compresses the received data in a case where the process reception processing unit receives the data, and stores the compressed data into a compressed data database, and a decompression processing unit that decompresses the compressed data stored in the compressed database at the predefined date and time before an acquisition process of acquiring data in another process, stored in the compressed database is started, and stores the decompressed data into a decompressed database, the acquisition process being included in the processes in the plural stages.
