MySQL超市管理系統(tǒng)數(shù)據(jù)庫是一種基于MySQL技術的管理系統(tǒng)數(shù)據(jù)庫,主要用于超市商場對商品、會員、銷售等信息的存儲和管理。該數(shù)據(jù)庫采用關系型數(shù)據(jù)庫管理系統(tǒng),能夠提供快速高效的數(shù)據(jù)查詢和編輯功能,以支持企業(yè)的管理需求。
以下是MySQL超市管理系統(tǒng)數(shù)據(jù)庫的表結構:
CREATE TABLE `tb_user` ( `user_id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(20) NOT NULL, `password` varchar(32) NOT NULL, `phone` varchar(20) DEFAULT NULL, `email` varchar(50) DEFAULT NULL, PRIMARY KEY (`user_id`), UNIQUE KEY `username` (`username`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8; CREATE TABLE `tb_goods` ( `goods_id` int(11) NOT NULL AUTO_INCREMENT, `goods_name` varchar(50) DEFAULT NULL, `goods_desc` varchar(200) DEFAULT NULL, `goods_price` double(10,2) DEFAULT NULL, PRIMARY KEY (`goods_id`) ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8; CREATE TABLE `tb_member` ( `member_id` int(11) NOT NULL AUTO_INCREMENT, `member_name` varchar(20) NOT NULL, `member_sex` varchar(2) DEFAULT NULL, `member_phone` varchar(20) DEFAULT NULL, `member_address` varchar(50) DEFAULT NULL, PRIMARY KEY (`member_id`), UNIQUE KEY `member_name` (`member_name`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8; CREATE TABLE `tb_sale_detail` ( `detail_id` int(11) NOT NULL AUTO_INCREMENT, `goods_id` int(11) NOT NULL, `price` double(10,2) NOT NULL, `quantity` int(11) NOT NULL, `total` double(10,2) NOT NULL, `sale_time` datetime NOT NULL, `user_id` int(11) NOT NULL, `member_id` int(11) NOT NULL, PRIMARY KEY (`detail_id`), KEY `goods_id` (`goods_id`), KEY `user_id` (`user_id`), KEY `member_id` (`member_id`), CONSTRAINT `tb_sale_detail_ibfk_1` FOREIGN KEY (`goods_id`) REFERENCES `tb_goods` (`goods_id`) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `tb_sale_detail_ibfk_2` FOREIGN KEY (`user_id`) REFERENCES `tb_user` (`user_id`) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `tb_sale_detail_ibfk_3` FOREIGN KEY (`member_id`) REFERENCES `tb_member` (`member_id`) ON DELETE CASCADE ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
在該數(shù)據(jù)庫中,tb_user表用于存儲用戶信息,tb_goods用于存儲商品信息,tb_member用于存儲會員信息,tb_sale_detail用于存儲銷售詳情信息。
通過這些表的結構,管理員可以通過SQL語句進行數(shù)據(jù)查詢、添加、修改和刪除等操作,從而實現(xiàn)對超市管理的便捷和高效。
