【摘要】：数据库技术经过多年的发展和进步，数据库从最初的存储各种简单数据的表格到今天演变成为能够存储海量数据的大型数据库系统。随着XML（可扩展标记语言）文件的广泛流行和应用，用户需要一种能够支持对海量XML格式文档进行高效存储和查询等操作的数据管理系统。正是在这种背景下，方正数字出版有限公司研发我国首款拥有自主知识产权的XML数据库产品方正智睿数据库。方正智睿XML数据库是一个能以Native方式高速存储，高速检索XML文档，具有完整事物处理能力，支持大规模并行处理的分布式数据库管理系统。在XML数据库中，文档被杂乱无章的存放在存储空间里，如果没有一种高效的组织管理的系统，将会给XML数据库各种功能的实现带来很大的困难以及给整个数据库系统造成很大的开销。方正智睿数据库使用一种全新XML文件管理系统文档集合管理系统。在该系统中，将会独创性的使用容器（Container）和集合（Collection）作为存储和管理XML文档的基本单位，其中容器作为存储物理文档的基本单位，集合作为逻辑上具有关联的XML文档的链接，数据字典模块对容器和集合的操作进行封装，并且用字典模块的图数据结构来记录所有容器，集合，，文档之间的关系，XML文档的添加，访问，删除等将会变得更加高效和简洁。相比较其他XML数据库，通过文档集合管理系统，方正智睿数据库中XML文档的管理效率得到很大的提升。
[Abstract]:After years of development and progress in database technology, Databases have evolved from tables that store a variety of simple data to a large database system that can store large amounts of data. With the popularity and application of XML (Extensible markup language) files, Users need a data management system capable of efficiently storing and querying massive XML format documents. Fangzheng Digital Publishing Co., Ltd. has developed the first XML database product with independent intellectual property rights. Fangzheng Zhirui XML database is a distributed database management system, which can be stored at high speed in Native mode and can retrieve XML documents at high speed. It has the ability of complete transaction processing and supports large-scale parallel processing. Documents are stored in storage space in disorder. If there is no efficient organization and management system, it will bring a lot of difficulties to the realization of various functions of XML database and great overhead to the whole database system. Fangzheng Zhirui Database uses a new XML file management system, document Collection Management system, in which the original use of containers and collections is used as the basic unit for storing and managing XML documents. The container is the basic unit of storing physical documents, the set is the link of the logically associated XML document, and the data dictionary module encapsulates the operation of the container and the collection. And using the graph data structure of the dictionary module to record all the containers, collections, the relationship between documents, the addition, access and deletion of XML documents will become more efficient and concise. Compared with other XML databases, through the document collection management system, Fangzheng Zhirui database XML document management efficiency has been greatly improved.
