基于Neo4j的无障碍设施数据存储与检索应用研究

Neo4j-Based Accessibility Data Storage and Retrieval Application Research

武汉公交地铁无障碍出行应用是一款主要辅助轮椅无障碍出行的工具,在对其进行无障碍设施数据维护过程中遇到了数据重复存储、错乱和梳理更新困难等问题。目前使用图数据库Neo4j应用于无障碍应用的研究较少,本文以武汉市地铁无障碍设施为例,对比武汉地铁无障碍出行移动应用中使用的MySQL和数据采集系统中使用的Neo4j两种数据库,通过阐述两者的存储表结构、使用利弊和查询表现后,以数据采集上报模块为应用点验证了使用Neo4j的可行性和有效性。

Wuhan bus and subway barrier-free travel application is a tool that mainly assists wheelchair ac-cessible travel. During the maintenance of its accessibility data, it encountered problems such as duplicate storage of data, misalignment and difficulty in sorting out and updating. At present, there are few studies using graph database Neo4j for accessible applications. This paper takes Wuhan subway accessibility as an example and compares two databases, MySQL used in Wuhan subway barrier-free travel mobile application and Neo4j used in data collection system, and verifies the feasibility and effectiveness of using Neo4j with data collection reporting module as an application point after elaborating the storage table structure, use advantages and disadvantages and query performance of both.
