 2-1 系统功能模块划分

前端展示系统功能

店家系统功能

超级管理员系统

 2-2 实体类设计与表创建A

系统涉及到的实体类：

  • 区域实体类属性

 权重：展示优先级

CREATE TABLE `tb_area` (
  `area_id` int(5) NOT NULL AUTO_INCREMENT,
  `area_name` varchar(200) NOT NULL,
  `area_desc` varchar(1000) DEFAULT NULL,
  `priority` int(2) NOT NULL DEFAULT '0',
  `create_time` datetime DEFAULT NULL,
  `last_edit_time` datetime DEFAULT NULL,
  PRIMARY KEY (`area_id`),
  UNIQUE KEY `UK_AREA` (`area_name`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

用户实体类属性

 

CREATE TABLE `tb_person_info` (
  `user_id` int(10) NOT NULL AUTO_INCREMENT,
  `name` varchar(32) DEFAULT NULL,
  `birthday` datetime DEFAULT NULL,
  `gender` varchar(2) DEFAULT NULL,
  `phone` varchar(32) DEFAULT NULL,
  `email` varchar(128) DEFAULT NULL,
  `profile_img` varchar(1024) DEFAULT NULL,
  `create_time` datetime DEFAULT NULL,
  `last_edit_time` datetime DEFAULT NULL,
  `enable_status` int(2) NOT NULL DEFAULT '0',
  PRIMARY KEY (`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

 2-3 实体类设计与表创建B

微信账号实体类属性

openId：微信账号与公众号绑定的唯一标识

CREATE TABLE `tb_wechat_auth` (
  `wechat_auth_id` int(10) NOT NULL AUTO_INCREMENT,
  `user_id` int(10) NOT NULL,
  `open_id` varchar(512) NOT NULL,
  `create_time` datetime DEFAULT NULL,
  PRIMARY KEY (`wechat_auth_id`),
  CONSTRAINT `fk_oauth_profile` FOREIGN KEY (`user_id`) REFERENCES `tb_person_info` (`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

本地账号实体类属性

 用户id将微信账号和本地账号绑定在一起

CREATE TABLE `tb_local_auth` (
  `local_auth_id` int(10) NOT NULL AUTO_INCREMENT,
  `user_id` int(10) DEFAULT NULL,
  `user_name` varchar(128) NOT NULL,
  `password` varchar(128) NOT NULL,

  `create_time` datetime DEFAULT NULL,
  `last_edit_time` datetime DEFAULT NULL,
  PRIMARY KEY (`line_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

店铺类别实体类属性

 

CREATE TABLE `tb_shop_category` (
  `shop_category_id` int(11) NOT NULL AUTO_INCREMENT,
  `shop_category_name` varchar(100) NOT NULL DEFAULT '',
  `shop_category_desc` varchar(1000) DEFAULT '',
  `shop_category_img` varchar(2000) DEFAULT NULL,
  `priority` int(2) NOT NULL DEFAULT '0',
  `create_time` datetime DEFAULT NULL,
  `last_edit_time` datetime DEFAULT NULL,
  `parent_id` int(11) DEFAULT NULL,

  CONSTRAINT `fk_shop_category_self` FOREIGN KEY (`parent_id`) REFERENCES `tb_shop_category` (`shop_category_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

 店铺实体类属性

建议：超级管理员对店铺的建议 

CREATE TABLE `tb_shop` (
  `shop_id` int(10) NOT NULL AUTO_INCREMENT,
  `owner_id` int(10) NOT NULL COMMENT '店铺创建人',

  `enable_status` int(2) NOT NULL DEFAULT '0',
  `advice` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`shop_id`),
  CONSTRAINT `fk_shop_area` FOREIGN KEY (`area_id`) REFERENCES `tb_area` (`area_id`),
  CONSTRAINT `fk_shop_profile` FOREIGN KEY (`owner_id`) REFERENCES `tb_person_info` (`user_id`),
  CONSTRAINT `fk_shop_shopcate` FOREIGN KEY (`shop_category_id`) REFERENCES `tb_shop_category` (`shop_category_id`)
