基于Java低级文件I/O的文件数据库系统

OBJECT ORIENTED FILE - DATABASE MANAGEMENT BASED ON Java LOW LEVEL I/O SYSTEM

本文讨论了一种基于Java低级随机存取文件I/O实现的面向对象的数据库管理系统,可以完成基本的数据操作如插入、检索、更新、删除、排序等,可在轻型的程序系统中直接以文件形式存储数据,从而避免对后台数据库(可能影响程序的跨平台发布)和JDBC等的依赖。

We discuss here an Object Oriented File - Database management system based on Java's low level file I/O interfaces (i.e. RandomAc-cessFile package) .When dealing with database manipulation,most small applications programs do not need a heavy loaded JDBC- ODBC bridge and the corresponding database server, and when considering cross - platform and easy - installing & running, people do need a light - weighted database management realization that only needs a cross - platformed file storage support with no background C/S structure for basic SELECT, INSERT, UPDATE, DELETE operations, and this the gaol of this paper.
