| Abstract: | There are some different solutions to the implement of tree catalog,and they will affect the efficiency of program execution.It is more important to choose a good solution for some systems which have a lot of data.The combination of database design and query algorithm is the great factor to the efficiency. The paper introduces some familiar algorithm and brings forward the mended design,at last points out the advantage of good algorithm and design. |
