| Summary: | A novel database structure data index method comprises a Hash index established in a vertical structure database. The index method of the Hash index comprises the following steps: a lookup table is generated in a mapping vertical table range of the vertical structure database according to a lookup content; the keyword to be searched is subject to Hash processing to obtain a Hash index value of thekeyword to be searched; and a matching content to be searched is searched in the lookup table according to the Hash index value of the keyword to be searched. The invention has the advantages of solving the problem that when the existing computer platform system processes the data, all the data need to be re-extracted when extracting the missed data; and improving the speed of data processing andthe reliability of platform system. The storage space is saved through the vertical storage technology.
种新型的库结构数据索引方法，包括竖结构数据库中建立的哈希索引，哈希索引的索引方法包括：根据查找内容在竖结构数据库的映射竖表范围内生成查找表；对待查找关键字进行哈希处理，获得待查找关键字的哈希索引值；根据待查找关键字的哈希索引值在查找表中查找到 |
