3、 ... and 、 database

Introduction to database tables

• Address table （tb_address）：  contain id、 Address information （detail）、 full name （name）、 Telephone （phone）、 user id（uid）、 Default address tag （level）
• Shopping cart table （tb_cart）：  contain id、 goods id（pid） Number （num）、 Subtotal （money）
• Commodity list （tb_goods）：  contain id、 Name of commodity （name）、 Add cart date （pubdate）、 picture （picture）、 The unit price （price）、 The star （star）、 describe （intro）、 Commodity type id（typeid）
• Commodity type table （tb_goods_type）：  contain id、 Commodity type name （name）、 Product type level （level）
• The order sheet （tb_order）：  Include orders id、 user id（uid）、 Subtotal （money）、 The order status （status）、 Order time （time）、 Address id（aid）
• Order details sheet （tb_orderdetail）：  contain id、 Order id（oid）、 goods id（pid）、 The number （num）、 Subtotal （money）
• User table （tb_user）：  contain id、 user name （username）、 password （password）、 mailbox （email）、 Gender （gender）、 Account activation flag （flag）、 Administrator tag （role）、 Activation code （code）

matters needing attention ：

• Account activation flag flag=1 Is active ; The default tag address is marked as 1
• code The activation code can be used UUID To generate , Remember to put UUID In the yard "-" Remove it
• Order ID It's a UUID Generated 32 Is a string type ID, Also want to put "-" Removed
• Order status we only use two statuses , If you need to view the status , It can be found in our project utils Enum classes in tools OrderStatus
• The order time in the database is time type , This type includes date and time .java.utils.date It contains date and time , and java.sql.date It only contains the date , Not including time . All we need in this project is to use java.utils.date that will do
• The subtotal in the shopping cart table is empty , It's because you store the subtotal once you add the goods to the shopping cart , But when you submit the order, change the quantity , The subtotal should also change . So this causes the subtotal in the shopping cart to be different from the subtotal in the order
• Emptying the shopping cart and deleting the items in the shopping cart are not direct delete Delete , Because of the value of user data , Therefore, we only need to operate the quantity of goods purchased by users
