分别通过文件访问技术，ADO+ORACLE数据库技术，ORACLE+XML技术进行数据处理的性能比较。其中数据库包含常用的关系数据库以及不常用的对象关系数据库，对于想学习对象数据库的人有一定的帮助，同时也包含层次模型数据的处理，对想同时进行xml以及oracle学习的人有很大的帮助。-File access through technology, ADO+ ORACLE database technology, ORACLE+ XML technology for data processing performance comparison. One database contains commonly used relational databases as well as commonly used in object-relational databases, object-oriented database to learn about people who have some help, but also contains the hierarchical model of data processing, at the same time to want to learn xml and oracle who has a lot of帮助.
