About the Improved Controllable Deriving Algorithm from Database

Data outputting, is a special command of database, and can derive the integrated data resources 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 implementing 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.
