Summary
This study proposes an effective caching strategy for XML medical data, enhancing accessibility and availability. The frequency-based caching method improves medical data retrieval efficiency.
Area of Science:
- Medical Informatics
- Computer Science
Background:
- Medical data is increasingly stored in XML format.
- Efficient access to medical records is crucial for healthcare.
Purpose of the Study:
- To propose and evaluate a caching scheme for XML medical data.
- To enhance the accessibility and availability of medical information.
Main Methods:
- Representing XML medical data as a tree structure.
- Implementing a caching process guided by data access frequency.
- Evaluating performance using cache and byte hit ratios with artificial patient records.
Main Results:
- The proposed caching scheme demonstrates significant effectiveness.
- Improved cache and byte hit ratios were observed.
- The system proved beneficial for accessing medical data.
Conclusions:
- Frequency-based caching is a viable strategy for optimizing XML medical data access.
- The developed caching mechanism enhances medical data availability and accessibility.
