摘要
南阳牛是我国的优良品种,建立该系统有助于管理利用好南阳牛的育种资料.加速其肉用育种.本系统采用dBASEⅢ语言,菜单驱动,汉化提示.建立了初生犊牛和6、12、18月龄育成牛育种资料数据库.系统包括建立、维护、查询、信息、咨询分析和输出6个功能模块.本文还介绍了实现各个主要功能模块的程序之设计技巧.其中,实现咨询分析的程序中调用了BASIC程序文件而进行复杂的运算.最后,对本系统的特点及需要完善的内容进行了分析、评价,并作了展望.
Nanyang Cattle is a fine breed in China. Establishment of such a system may help to make good use of Nanyang Cattle breeding data and quicken the pace of their selection for meat purpose. Menu driven and Chinese prompted. this system adopted the language of dBASE Ⅲ,and set up breeeing data bases for newly- born calves and growing cattle at 6,12 and 18 months of age. Six functional modules of file creation, maintenance, inquiry, information, consulting analysis and output were integrated into the system. Techniques of designing programs for each functional module were described. As for the program for consulting analysis, BASIC program files were -called for complex arithmetic operations. Features, imperfections and prospects for this system were also evaluated.
