  " pages " int ,
  " description " text ,
  " image_url " varchar ( 1200 ),
  " reviews " int ,
  " rating " float
);

CREATE TABLE RegUser (
  " user_id " varchar ( 200 ) PRIMARY KEY ,
  " first_name " varchar ( 200 ) NOT NULL ,
  " last_name " varchar ( 200 ),
  " gender " varchar ( 200 ) NOT NULL ,
  " email " varchar ( 200 ) UNIQUE NOT NULL ,
  " password " varchar ( 200 ) NOT NULL ,
  " is_admin " boolean NOT NULL

CREATE TABLE Review
(
    " review_id " varchar ( 200 ) PRIMARY KEY ,

    " issue_date " varchar ( 200 ),
    " return_date " varchar ( 200 ),

);

ALTER TABLE Review ADD FOREIGN KEY ( " user_id " ) REFERENCES RegUser ( " user_id " );
ALTER TABLE Review ADD FOREIGN KEY ( " book_id " ) REFERENCES Book ( " book_id " );

ALTER TABLE BookIssue ADD FOREIGN KEY ( " user_id " ) REFERENCES RegUser ( " user_id " );
ALTER TABLE BookIssue ADD FOREIGN KEY ( " book_id " ) REFERENCES Book ( " book_id " );

很少有基本功能已經實現，其他功能可以實現或可以在此基礎上建構。所有實現的功能包括

    GetBookById
    AddBook
    DeleteBook
    SearchBook
    GetReviewsOfBook
    IssueBook
    GetIssueById
    GetBooksIssuedByUser
    Connect

文件結構及功能

main.go中呼叫的db/db.go的Connect()方法用於連接到本地或雲端資料庫並實例化一個全域變數Lib外部使用者可以使用該變數根據可用功能與資料庫實例進行互動。
在db內部，這些檔案包含直接與資料庫互動的程式碼，而資料庫又提供了上述方法。任何新方法和測試都應添加到此處。
