摘 要
网络技术和计算机技术发展至今,已经拥有了深厚的理论基础,并在现实中进行了充分运用,尤其是基于计算机运行的软件更是受到各界的关注。加上现在人们已经步入信息时代,所以对于信息的宣传和管理就很关键。因此海鲜餐厅信息的管理计算机化,系统化是必要的。设计开发海鲜自助餐厅系统不仅会节约人力和管理成本,还会安全保存庞大的数据量,对于海鲜餐厅信息的维护和检索也不需要花费很多时间,非常的便利。
海鲜自助餐厅系统是在MySQL中建立数据表保存信息,运用Vue框架和Java语言编写。并按照软件设计开发流程进行设计实现。系统具备友好性且功能完善。其实现的功能包括食物库存管理,海鲜展示管理,未预定餐桌管理,已预订餐桌管理,流水管理等功能。
海鲜自助餐厅系统在让海鲜餐厅信息规范化的同时,也能及时通过数据输入的有效性规则检测出错误数据,让数据的录入达到准确性的目的,进而提升海鲜自助餐厅系统提供的数据的可靠性,让系统数据的错误率降至最低。
