摘要
通过把液压支架的网状工程数据模型转换为层次数据模型,层次数据模型转换为关系数据模型,并采用混合链表结构进行存储,实现了液压支架工程数据的管理。该方法提高了数据的存取速度,使数据具有较好的开放性和重用性。
First, the original net mode of engineering data into layer mode is changed. Next, change the layer mode of data into two dimension data table of relation database and store the two dimension data by mixing chain table structure. The management of engineering data is realized. The speed of storing and taking data is improved by the approach. The publicity and recycling of data are better.
