实现数据库资源可控制导出的改进算法

About the Improved Controllable Deriving Algorithm from Database

导出,是数据库的一种专用命令,根据用户需求,将数据资源整合输出,其中需要涉及排序算法、检索算法等。普通系统资源整合算法在执行过程中,通常需要改变数据库资源存储结构,不利于系统平台的管理维护。文章设计一种改进算法,通过建立地址数组,存储数据资源地址,并在不改变数据库存储结构的前提下,仅通过不同数据资源地址位的改变,实现资源有效排序输出,提高数据库的安全性和可维护性,降低重复检索操作的计算复杂度,并利用面向对象技术搭建图书资源管理平台,进行算法仿真,呈现算法思路。

Data outputting, is a special command of database, and can derive the integrated data re-sources according to the user’s needs, which involves sorting algorithm, searching algorithm and so on. Common system integration algorithm, often needs to change the database storage structure in the imple-menting process, and is not conducive to maintenance of management system platform. This paper designs an improved algorithm, through creating address array, storing the address of data resources, realizing resources sorting output efficiently only by changing the address of data resources and the database storage structure stays the same, improving the security and maintainability of the database and reducing the computation complexity of searching repeatedly, and building a book resource management platform by object-oriented technology, and presents the mentality of algorithm by simulation.
