Geriatric cognitive impairment is becoming a major threat to elderly’s life quality, but preventive measures, treatment technologies, and health care models are still immature for the elderly with cognitive impairment. Additionally, there is a lack of data systems for cognitive impairment in the elderly that can store these medical data in a complete and disaggregated manner. These lead to inaccurate diagnosis of cognitive impairment, delayed treatment of cognitive impairment, and unavailable appropriate medical care for cognitive impairment patients. To address these problems, this study designs a B/S-based multidimensional data management system for cognitive impairment in the elderly. The system takes advantage of the FastDFS distributed file storage system to ensure the security and stability of the system data. The recursive tree structure is adopted to extract the tabular data and speed up the screening process. The system is compatible with current major browsers.
