1、 中文摘要 继电保护具有很多非结构化数据（ Word、 Excel、 GIS、 PDF、文本等格式），而非结构化 数据具有文件小、数量多、异构、多源等特点， 为了将这些数据有效的进行管理，有必要研究一个方法可以科学管理、高效访问这些数据。本文深入研究了 继电保护非结构化数据的特点及其保存机制，采用 SQL Server 的面向对象特性，建立科学、合理的数据模型， 实现 Word、 Excel、 JPG、 AVI、 TXT、PPT 等所有格式数据的保存及管理和关 联 。并研究 大型数据库实体的建立方法、存储方法、优化方法、参数调整等内容，以及 快 速提取 数据库中数据的方法，主要包括使用存储过程
2、、查询优化、索引等技术手段。最后通过 C#语言 开发出继保异构数据管理系统， 实现系统的全部功能（ 保存、查询、显示、修改等 ）。并将本文提出的各项关键技术集成在该系统中，选取继保异构数据表进行测试。 关键词 继电保护异构数据 优化查询 C#开发 外文摘要 Title The Mangement System for relay protection Heterogeneous Database Abstract The Management System for relay protection Heterogeneous Database Relay protection has many
