Abstractor: This topic is "The Income-Sell-Stock System Of Garment Enterprise——Main office management subsystem", take the clothing enterprises in headquarters as the design object, for the headquarters system in each kind of documentary evidence establishment unified database, utilizes the small ERP system which the object-oriented thought develops.

经济的全球化，给服装企业带来无限商机，同时也给服装企业的生产制造带来越来越大的压力。许多企业通过采用新技术，引进服装CAD技术来改变生产工艺，提高产品质量；通过采用电子商务系统，进行网上营销，获得市场信息。在激烈的市场竞争环境中，单靠这些是不够的，不能为一个服装企业在管理上提供更多的帮助，而企业的管理，资源合理的计划和控制才是企业能够长期发展的有效保证，为此服装ERP系统应运而生。
