摘要
数据存储与查询是组态软件中的重要组成部分,但是传统的方法效率低,因此对其进行改进,提高查询效率对于组态软件有着重要的意义。融合了数据库索引思想的新方法,不仅减小了存储文件的大小,而且大大提高了查询的效率。
Data store and data query are important parts of configuration software, but the traditional method is inefficient, so it has important significance for configuration software to impi＇ove its query efficiency. The new method, including the index theory of database, not only decreases the size of data store file, but also improves the efficiency of data query.
