常见电商项目的数据库表设计(MySQL版) - 简书
- -电商常用功能模块的数据库设计. 改进1:第三范式:将依赖传递的列分离出来. 比如:登录名<-用户级别<-级别积分上限,级别积分下限. 改进2:尽量做到冷热数据的分离,减小表的宽度. 用户登录表(customer_login). 用户信息表(customer_inf). 用户级别表(customer_level_inf).
用户表涉及的实体
改进1:第三范式:将依赖传递的列分离出来
比如:登录名<-用户级别<-级别积分上限,级别积分下限
改进2:尽量做到冷热数据的分离,减小表的宽度
用户登录表(customer_login)
CREATE TABLE customer_login(
customer_id INT UNSIGNED AUTO_INCREMENT NOT NULL COMMENT '用户ID',
login_name VARCHAR(20) NOT NULL COMMENT '用户登录名',

mobile_phone INT UNSIGNED COMMENT '手机号',
customer_email VARCHAR(50) COMMENT '邮箱',
gender CHAR(1) COMMENT '性别',
user_point INT NOT NULL DEFAULT 0 COMMENT '用户积分',
register_time TIMESTAMP NOT NULL COMMENT '注册时间',

PRIMARY KEY pk_customerinfid(customer_inf_id)
) ENGINE = innodb COMMENT '用户信息表';
CREATE TABLE customer_level_inf(

level_name VARCHAR(10) NOT NULL COMMENT '会员级别名称',
min_point INT UNSIGNED NOT NULL DEFAULT 0 COMMENT '该级别最低积分',

modified_time TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '最后修改时间',
PRIMARY KEY pk_levelid(customer_level)
) ENGINE = innodb COMMENT '用户级别信息表';
CREATE TABLE customer_addr(
customer_addr_id INT UNSIGNED AUTO_INCREMENT NOT NULL COMMENT '自增主键ID',
customer_id INT UNSIGNED NOT NULL COMMENT 'customer_login表的自增ID',
zip SMALLINT NOT NULL COMMENT '邮编',

CREATE TABLE customer_point_log(

change_point SMALLINT NOT NULL DEFAULT 0 COMMENT '变更积分数',
create_time TIMESTAMP NOT NULL COMMENT '积分日志生成时间',
PRIMARY KEY pk_pointid(point_id)

CREATE TABLE customer_balance_log(

CREATE TABLE customer_login_log(

分区表特点:逻辑上为一个表,在物理上存储在多个文件中
CREATE TABLE customer_login_log(
login_id INT UNSIGNED NOT NULL AUTO_INCREMENT COMMENT '登陆日志ID',
customer_id INT UNSIGNED NOT NULL COMMENT '登陆用户ID',
login_time TIMESTAMP NOT NULL COMMENT '用户登陆时间',
login_ip INT UNSIGNED NOT NULL COMMENT '登陆IP',
login_type TINYINT NOT NULL COMMENT '登陆类型:0未成功,1成功',
PRIMARY KEY pk_loginid(login_id)
) ENGINE = innodb COMMENT '用户登陆日志表'
PARTITION BY HASH(customer_id) PARTITIONS 4;
区别就在于加了 PARTITION
这个命令。
文件结构上的区别
customer_login_log.frm
customer_login_log.ibd
customer_login_log.frm
customer_login_log#P#p0.ibd
customer_login_log#P#p1.ibd
customer_login_log#P#p2.ibd
customer_login_log#P#p3.ibd
按HASH分区的特点
UNIX_TIMESTAMP(login_time)
特点:
CREATE TABLE customer_login_log(
login_id INT UNSIGNED NOT NULL AUTO_INCREMENT COMMENT '登陆日志ID',
customer_id INT UNSIGNED NOT NULL COMMENT '登陆用户ID',
login_time TIMESTAMP NOT NULL COMMENT '用户登陆时间',
login_ip INT UNSIGNED NOT NULL COMMENT '登陆IP',
login_type TINYINT NOT NULL COMMENT '登陆类型:0未成功,1成功',
PRIMARY KEY pk_loginid(login_id)
) ENGINE = innodb COMMENT '用户登陆日志表'
PARTITION BY RANGE (customer_id) (
PARTITION p0 VALUES LESS THAN (10000),
PARTITION p1 VALUES LESS THAN (10000),
PARTITION p2 VALUES LESS THAN (10000),
PARTITION p3 VALUES LESS THAN MAXVALUE
);
Range分区的适用范围
特点:
CREATE TABLE customer_login_log(
login_id INT UNSIGNED NOT NULL AUTO_INCREMENT COMMENT '登陆日志ID',
customer_id INT UNSIGNED NOT NULL COMMENT '登陆用户ID',
login_time TIMESTAMP NOT NULL COMMENT '用户登陆时间',
login_ip INT UNSIGNED NOT NULL COMMENT '登陆IP',
login_type TINYINT NOT NULL COMMENT '登陆类型:0未成功,1成功',
PRIMARY KEY pk_loginid(login_id)
) ENGINE = innodb COMMENT '用户登陆日志表'
PARTITION BY LIST (login_type) (
PARTITION p0 VALUES (1,3,5,7,9),
PARTITION p1 VALUES (2,4,6,8)
);
业务场景:
解决:
如何查看分区是否正确:
information_schema.PARTITIONS
ALTER TABLE customer_login_log ADD PARTITION (PARTITION p4 VALUES LESS THAN(2018))
ALTER TABLE customer_login_log DROP PARTITION p0;
CREATE TABLE arch_customer_login_log(

login_type TINYINT NOT NULL COMMENT '登陆类型:0未成功,1成功',
PRIMARY KEY pk_loginid(login_id)

ALTER TABLE customer_login_log EXCHANGE PARTITION p1 WITH TABLE arch_customer_login_log
ALTER TABLE customer_login_log DROP PARTITION p2

为以后数据库迁移提供方便
避免跨库操作,把经常一起关联查询的表放到一个DB中
为方便识别表所在的DB,在表名前增加库名前缀
用户数据库(mc_customerdb)
商品数据库(mc_productdb)
订单数据库(mc_orderdb)
