1、在storename11数据库创建员工表(person1)、商品表(goods1)和销售表(sales1)三张表 (1)员工表的表结构如下: 在Navicate可视化界面中用语句创建该表,截图在下方 表名:person1 字段名 字段类型 长度 含义备注 Ano Char 10 员工编号 Aname Char 20 员工姓名 Asex Char 2 性别 Aage int 员工年龄 Aaddress Char 40 员工家庭住址

可以使用以下 SQL 语句在 storename11 数据库中创建员工表 person1:
```sql
CREATE TABLE person1 (
Ano CHAR(10) PRIMARY KEY,
Aname CHAR(20),
Asex CHAR(2),
Aage INT,
Aaddress CHAR(40)
);
```
以下是在 Navicat 可视化界面中截图的示例:

sql server创建超市销售分析数据库,建立事实表,商品表,商店表,时间表,并设置主键及参照约束
在SQL Server中创建一个超市销售分析数据库通常涉及以下几个步骤:
1. **创建数据库**:
使用 `CREATE DATABASE` 语句创建一个新的数据库,例如 "SupermarketSalesDB"。
```sql
CREATE DATABASE SupermarketSalesDB;
```
2. **创建表 - 事实表(Fact_Sales)**:
这张表用于存储详细的销售数据,可以包括销售ID、商品ID、商店ID、销售日期等信息。设置 "SaleID" 为主键。
```sql
CREATE TABLE Fact_Sales (
SaleID INT PRIMARY KEY,
ProductID INT,
StoreID INT,
SaleDate DATE NOT NULL,
QuantitySold INT,
SaleAmount DECIMAL(10, 2)
);
```
3. **创建表 - 商品表(Product)**:
保存商品的信息,如商品ID、名称、类别等,"ProductID" 作为主键。
```sql
CREATE TABLE Product (
ProductID INT PRIMARY KEY,
ProductName VARCHAR(50),
Category VARCHAR(50),
Price DECIMAL(10, 2)
);
```
4. **创建表 - 商店表(Store)**:
包含商店的ID、名称和地址信息,"StoreID" 作为主键。
```sql
CREATE TABLE Store (
StoreID INT PRIMARY KEY,
StoreName VARCHAR(50),
Address VARCHAR(100)
);
```
5. **创建表 - 时间表(TimeDimension)**:
时间维度表用来记录日期和其他时间相关的详细度量,如星期、季度等。假设 "DateKey" 表示时间序列。
```sql
CREATE TABLE TimeDimension (
DateKey INT IDENTITY(1, 1) PRIMARY KEY,
SalesDate DATE NOT NULL,
DayOfWeek TINYINT,
MonthOfYear SMALLINT,
Quarter YEAR,
Year INT
);
```
6. **关联表之间的外键约束**:
使用 FOREIGN KEY 来确保数据一致性,如将 "ProductID" 和 "StoreID" 引用到对应的主键。
```sql
ALTER TABLE Fact_Sales
ADD FOREIGN KEY (ProductID) REFERENCES Product(ProductID);
ALTER TABLE Fact_Sales
ADD FOREIGN KEY (StoreID) REFERENCES Store(StoreID);
ALTER TABLE Fact_Sales
ADD FOREIGN KEY (SaleDate) REFERENCES TimeDimension(SaleDate);
```
CREATE TABLE CUSTOMER ( CustomerID NUMBER(10) PRIMARY KEY, FirstName VARCHAR2(50), LastName VARCHAR2(50), Email VARCHAR2(100), PhoneNumber VARCHAR2(20) ); 1.创建ORDER表: CREATE TABLE Orders ( OrderID NUMBER(10) PRIMARY KEY, OrderDate DATE, OrderStatus VARCHAR2(20), TotalCost NUMBER(10,2), CustomerID NUMBER(10), FOREIGN KEY (CustomerID) REFERENCES CUSTOMER(CustomerID) ); 1.创建PRODUCT表: CREATE TABLE PRODUCT ( ProductID NUMBER(10) PRIMARY KEY, ProductName VARCHAR2(100), Description VARCHAR2(500), Price NUMBER(10,2), Category VARCHAR2(50) ); 1.创建ORDER_DETAILS表: CREATE TABLE ORDER_DETAILS ( OrderDetailID NUMBER(10) PRIMARY KEY, ProductName VARCHAR2(100), Price NUMBER(10,2), Quantity NUMBER(10), Subtotal NUMBER(10,2), OrderID NUMBER(10), ProductID NUMBER(10), FOREIGN KEY (OrderID) REFERENCES ORDERS(OrderID), FOREIGN KEY (ProductID) REFERENCES PRODUCT(ProductID) ); 1.创建STORE表: CREATE TABLE STORE ( StoreID NUMBER(10) PRIMARY KEY, StoreName VARCHAR2(100), Location VARCHAR2(200), HoursOfOperation VARCHAR2(200) ); 1.创建INVENTORY表: 1.CREATE TABLE INVENTORY ( ProductID INT NOT NULL, StoreID INT NOT NULL, Quantity INT NOT NULL, ReorderPoint INT NOT NULL, PRIMARY KEY (ProductID, StoreID), CONSTRAINT fk_product FOREIGN KEY (ProductID) REFERENCES Product(ProductID), CONSTRAINT fk_store FOREIGN KEY (StoreID) REFERENCES Store(StoreID) ); 2.创建TRANSACTION表: CREATE TABLE TRANSACTION ( TransactionID NUMBER(10) PRIMARY KEY, TransactionDate DATE, TransactionType VARCHAR2(20), TotalAmount NUMBER(10,2), CustomerID NUMBER(10), FOREIGN KEY (CustomerID) REFERENCES CUSTOMER(CustomerID) ); 1.创建TRANSACTION_DETAILS表: CREATE TABLE TRANSACTION_DETAILS ( TransactionDetailID NUMBER(10) PRIMARY KEY, ProductName VARCHAR2(100), Price NUMBER(10,2), Quantity NUMBER(10), Subtotal NUMBER(10,2), TransactionID NUMBER(10), ProductID NUMBER(10), FOREIGN KEY (TransactionID) REFERENCES TRANSACTION(TransactionID), FOREIGN KEY (ProductID) REFERENCES PRODUCT(ProductID) ); 1.创建EMPLOYEE表: CREATE TABLE EMPLOYEE ( EmployeeID NUMBER(10) PRIMARY KEY, Name VARCHAR2(100), Address VARCHAR2(200), PhoneNumber VARCHAR2(20), Email VARCHAR2(100), Position VARCHAR2(50) ); 1.创建SALARY表: CREATE TABLE SALARY ( EmployeeID NUMBER(10), StartDate DATE, EndDate DATE, SalaryAmount NUMBER(10,2), PRIMARY KEY (EmployeeID, StartDate), FOREIGN KEY (EmployeeID) REFERENCES EMPLOYEE(EmployeeID) ); 1.创建SHIFT表: CREATE TABLE SHIFT ( ShiftID NUMBER(10) PRIMARY KEY, StartTime DATE, EndTime DATE, StoreID NUMBER(10), EmployeeID NUMBER(10), FOREIGN KEY (StoreID) REFERENCES STORE(StoreID), FOREIGN KEY (EmployeeID) REFERENCES EMPLOYEE(EmployeeID) );写出导出这些表的数据字典的oracle语句
Oracle中可以使用以下语句导出数据字典:
SELECT table_name, column_name, data_type, data_length, nullable
FROM user_tab_columns
WHERE table_name IN ('CUSTOMER', 'ORDERS', 'PRODUCT', 'ORDER_DETAILS', 'STORE', 'INVENTORY', 'TRANSACTION', 'TRANSACTION_DETAILS', 'EMPLOYEE', 'SALARY', 'SHIFT')
ORDER BY table_name, column_id;
这将查询指定表的列信息,并按表名和列ID排序。可以将查询结果导出为CSV或Excel文件以获取数据字典。
