| 摘 要： | 本程序基于通信线路资源管理系统,需要把老系统数据导入新系统中.由于新老系统数据结构不同,且基于WebGIS地理信息系统,数据特殊,数据量大,手工导入数据费时费力,用数据导入软件又不能很好满足本系统导入数据需要.所以需要设计一套可移植性和可操作性较好的程序来进行数据的迁移,能够对老系统的地理信息进行准确处理,从而将有用数据迁移到新系统的数据库中.

| Abstract: | This Program Resource Management System based on communication lines,needed to import the Old System data to the New System.The System was WebGIS-based Geographic Information System.As the Old and the New System data structures were different,it was time-consuming manual import data,and there was not a software to meet the needs of the System.So it was necessary to design a better portability and operability of the procedures for data migration.The Old System could be accurate geographical information proce... |
