これは、貸出図書館によって保存および処理されるデータを維持するために使用できる単純なデータベースです。このデータベースは、Microsoft のPubsデータベースを変更して設計されています。 Pubsデータベースは、書籍の出版社、著者、タイトル、販売に関する一連の架空の情報を提供します。現在では時代遅れとみなされています。 2008 バージョン以降、 SQL Serverでは提供されなくなりました。テーブルとフィールドは非常に明白です。これらには、その内容を反映するAuthors 、 Titlesなどの名前が付いています。また、フィールドには、その内容を説明するわかりやすい名前も付いています。
オリジナルの Pubs DB の詳細については、次のリンクを参照してください: Microsoft Pubs DB
以下に、変更されたPubsデータベースのデータベース図を示します。

END [dbo].[USP_InsertBook]ストアド プロシージャは、ブックだけを作成するわけではないため、少し複雑です。その新しい本に関連付けられた出版社や著者が存在しない場合、ユーザーがそれらを作成することもできます。そのため、 [dbo].[USP_InsertBook]ストアド プロシージャの@pub_idパラメーターと@author_idパラメーターはオプションです。ユーザーがフロントエンド アプリのドロップダウン メニュー要素から既存の発行者または作成者を選択すると、選択されたオプションの選択された値が@pub_idまたは@author_idの形式でストアド プロシージャに渡されます。新しい本の著者または出版社がドロップダウン メニュー (またはデータベース) に見つからない場合は、アプリを使用して簡単に作成できます。ドロップダウン メニューの最後のオプション [ Create New Author...およびCreate New Publisher...を使用すると、ユーザーは新しい著者または発行者を作成できます。また、本には前編がある場合とない場合があります。これらすべてを考慮すると、本を作成するシナリオは 4 つ考えられます。
注: ドロップダウン メニュー項目には、データベース内の既存の著者と発行者が入力されます。

Rule for deleting a book
- Publisher related to that title will not be deleted
- PublisherInfo related to the Publisher of that title will not be deleted
- Author related to that title will not be deleted
- Records related to that title from Titles and TitleAuthor tables will be deleted
Because there are publishers without any title on the initial database created by Microsoft (ex: pub_id with 1622 and 1756)
SELECT DISTINCT pub_id
FROM publishers
WHERE pub_id NOT IN

SELECT DISTINCT pub_id FROM titles

図書館では、本を借りたい人に図書カードを発行しています。図書館は、 card id 、 borrower name 、 address 、 phone number 、 birthdate 、 date the card was issued 、およびbalance due保存することにより、各借主のリストを保管します。カードの有効期限は発行日から10 年です。人物が18 歳未満の場合、図書館はname 、 address 、 phone numberなどの借り手の親または法定後見人に関する情報も保管します。一人が一度に持つことができる有効な図書館カードは 1 枚だけです。期限切れのカードでお金を借りている人には、新しい図書館カードを発行してもらうことはできません。
