成人学员对数据量大且不索引的FOXBASE(DBASE)数据库,在顺序查找时速度很慢。在教学中,我摸索到一种新的算法:直接定位法,改进了数据库定位速度,提高了学员的顺序查找速度。目前在数据库管理中,数据库记录定位是一个重要的因素,它影响记录提取的速度,尤其对数据量大的数据库。如对超过一万条记录,且不允许进行索引的数据库,提取一条记录平均需40秒左右,这样使得程序运行显得十分缓慢,影响程序质量。我摸索到的
Adult students FOXBASE (DBASE) database for large amounts of data and does not index slow in the sequential search. In teaching, I found a new algorithm: direct positioning method, improving the speed of database positioning, improve the speed of students to find the order. Currently in database management, database record positioning is an important factor, which affects the speed of record extraction, especially for a large amount of data in the database. For example, for a database of more than 10,000 records that are not allowed to be indexed, it takes about 40 seconds to extract a record, which causes the program to run very slowly and affects the quality of the program. I found it
