利用SQL Server Management Studio对象资源管理器建立帐户信息数据库，并定义以下基本表： 帐户（帐户编号，姓名，余额，建立日期，储蓄所编号） 储蓄所（储蓄所编号，名称，地址，人数，所属城市） 借贷（帐户编号，借贷类型，金额，日期）用代码输入数据

以下是建立帐户信息数据库和定义基本表的SQL代码：

CREATE DATABASE AccountInfo;

USE AccountInfo;

CREATE TABLE Account (
    AccountNumber INT PRIMARY KEY,
    Name VARCHAR(50) NOT NULL,
    Balance DECIMAL(18,2),
    CreationDate DATE,
    SavingsBankNumber INT,
    FOREIGN KEY (SavingsBankNumber) REFERENCES SavingsBank(SavingsBankNumber)
);

CREATE TABLE SavingsBank (
    SavingsBankNumber INT PRIMARY KEY,
    Name VARCHAR(50) NOT NULL,
    Address VARCHAR(100),
    NumberOfPeople INT,
    City VARCHAR(50)
);

CREATE TABLE Loan (
    AccountNumber INT,
    LoanType VARCHAR(50),
    Amount DECIMAL(18,2),
    Date DATE,
    FOREIGN KEY (AccountNumber) REFERENCES Account(AccountNumber)
);

INSERT INTO SavingsBank VALUES (1, 'ABC Savings Bank', '123 Main St.', 100, 'New York');
INSERT INTO SavingsBank VALUES (2, 'XYZ Savings Bank', '456 Maple Ave.', 200, 'Los Angeles');

INSERT INTO Account VALUES (1, 'John Smith', 5000.00, '2021-01-01', 1);
INSERT INTO Account VALUES (2, 'Jane Doe', 10000.00, '2021-02-15', 2);

INSERT INTO Loan VALUES (1, 'Personal Loan', 1000.00, '2021-03-01');
INSERT INTO Loan VALUES (2, 'Car Loan', 5000.00, '2021-04-15');
