Esta tabla no cumple el requisito de la Primera Forma Normal (1NF) de sólo tener campos atómicos, pues el

nombre del lector es un campo que puede (y conviene) descomponerse en apellido paterno, apellido materno

y nombres. Tal como se muestra en la siguiente tabla.

La Segunda Forma Normal (2NF) pide que no existan dependencias parciales o dicho de otra manera, todos los

atributos no clave deben depender por completo de la clave primaria. Actualmente en nuestra tabla tenemos

varias dependencias parciales si consideramos como atributo clave el código del libro.

Por ejemplo, el título es completamente identificado por el código del libro, pero el nombre del lector en

realidad no tiene dependencia de este código, por tanto estos datos deben ser trasladados a otra tabla.

La nueva tabla sólo contendrá datos del lector.

501 Pérez Gómez Juan

502 Ríos Terán Ana

503 Roca René

504 García Roque Luis

Hemos creado una tabla para contener los datos del lector y también tuvimos que crear la columna CodLector

para identificar unívocamente a cada uno. Sin embargo, esta nueva disposición de la base de datos necesita

que exista otra tabla para mantener la información de qué libros están prestados a qué lectores. Esta tabla se

muestra a continuación:

Page 11: MARACAIBO, 15 DE NOVIEMBRE DEL 2010 UNEFA …s4f4a6e0c58d15cfc.jimcontent.com/download/version/1347683833/mod… · XAMPP: Starting MySQL... XAMPP: Starting ProFTPD... XAMPP for Linux

1006 504 20/04/2005

1007 501 18/04/2005

Para la Tercera Forma Normal (3NF) la relación debe estar en 2NF y además los atributos no clave deben ser

mutuamente independientes y dependientes por completo de la clave primaria. También recordemos que

dijimos que esto significa que las columnas en la tabla deben contener solamente información sobre la

entidad definida por la clave primaria y, por tanto, las columnas en la tabla deben contener datos acerca de

una sola cosa. En nuestro ejemplo en 2NF, la primera tabla conserva información acerca del libro, los autores y

editoriales, por lo que debemos crear nuevas tablas para satisfacer los requisitos de 3NF.

Aunque hemos creado nuevas tablas para que cada una tenga sólo información acerca de una entidad,

también hemos perdido la información acerca de qué autor ha escrito qué libro y las editoriales

correspondientes, por lo que debemos crear otras tablas que relacionen cada libro con sus autores y

editoriales.
