空间数据库的WFS长事务管理方案研究

Research of WFS Long-Lived Transaction Management Schema Based on Spatial Database

在研究网络要素服务WFS-T对长事务管理的需求以及Geoserver等WFS服务器实现技术的基础上,针对目前进程内锁、行锁长事务管理方案未完全保证强事务性和事务持久性的问题,设计了一种包括长事务锁定表、授权校验规则和相应的SQL函数接口的空间数据库长事务管理方案;并在国产地理空间数据库管理系统BeyonDB上进行了验证。

Based on the requirement of WFS-T for the management of long-lived transaction and the technology of Geoserver, aiming at the situation that In-Process Lock Schema and Row Lock Schema don＇t ensure the supportment to strong-transaction and the persistence of transactions, a spatial database long-lived transaction management schema, which includes long-transaction lock table, rules of authority and related SQL function interface, was designed. The schema has been integrated with the BeyonDB geo-spatial database management system and proved it＇s feasible and practical.
