Jose GomezMongoDB and PHP is a book that obviously describes how to use MongoDB with PHP. The target readers of this book are PHP programmers that are newbies in MongoDB. This book covers MongoDB basics as a noSQL database comparing it with SQL databases and PHP programming.
The book is divided in 4 chapters. The first chapter describes the difficulties to store objects in Relational databases. Since PHP programming can be object oriented, the book explains why relational databases are not the best approach for data storage in PHP.
MongoDB is a document based database, the relationship between document and objects is explained in the first chapter. MongoDB is optimized for CRUD operations (Create, Read, Update and Delete) throught an optimal interface, performance and simplicity for handling CRUD operations.
