目前关系数据库中的水印算法已经无法满足其基本数据管理需求，而传统的遗传算法由于在水印嵌入中的元组个数远远无法满足数据库中的元组数量也没有得到实际的应用。笔者将通过对现有水印技术进行分析和探究，并基于遗传算法的基础之上来对关系数据库水印技术进行改进，该技术能够利用遗传算法在关系数据库中选择最优元组进行比对，极大缩短了关系数据库的水印嵌入时间，提高了水印嵌入效率，真正实现了关系数据库水印的优化，为关系数据库的发展做出了一定的贡献。

The current watermark algorithm for relational databases have been unable to meet their basic data management needs,and traditional genetic algorithm as the number of tuples in the watermark is embedded in the far cannot meet the requirements of application number in a database tuple has not obtained the actual.The author will use to analyze and study the existing watermarking techniques,and the relational database watermarking technique makes up the genetic algorithm based on improved,the technique could select the optimal tuple in the relational database are compared by using genetic algorithm,greatly shorten the relational data watermarking embedding time base,improve the embedding efficiency,realize the optimization of relational database watermarking,has made certain contribution to the development of relational database.
