CRUD con MySQLi en PHP – 0. Introducción

PDF 📄

Una de las principales funcionabilidades que debemos dar a nuestras aplicaciones es la persistencia. No todos los programas son iguales pero es obvio que muchos de ellos sirven para introducir información por parte de los usuarios y luego procesarla para obtener algún resultado.

Tiendas de productos, CRM, Blogs de noticias, todos necesitan un lugar donde guardar los datos. Estos datos pueden guardarse con muchos métodos, como puede ser almacenándolos en documentos XML o JSON entre otros.

En este caso, vamos a trabajar con uno de los sistemas de persistencia más extendidos en la actualidad, aunque no el único.  Este son las Bases de Datos relacionales, concretamente vamos a utilizar el gestor de MySQL.
