PHP and MongoDB Web Development Beginner's Guide

Overview of this book

With the rise of Web 2.0, the need for a highly scalable database, capable of storing diverse user-generated content is increasing. MongoDB, an open-source, non-relational database has stepped up to meet this demand and is being used in some of the most popular websites in the world. MongoDB is one of the NoSQL databases which is gaining popularity for developing PHP Web 2.0 applications.PHP and MongoDB Web Development Beginner’s Guide is a fast-paced, hands-on guide to get started with web application development using PHP and MongoDB. The book follows a “Code first, explain later” approach, using practical examples in PHP to demonstrate unique features of MongoDB. It does not overwhelm you with information (or starve you of it), but gives you enough to get a solid practical grasp on the concepts.The book starts by introducing the underlying concepts of MongoDB. Each chapter contains practical examples in PHP that teache specific features of the database.The book teaches you to build a blogging application, handle user sessions and authentication, and perform aggregation with MapReduce. You will learn unique MongoDB features and solve interesting problems like real-time analytics, location-aware web apps etc. You will be guided to use MongoDB alongside MySQL to build a diverse data back-end. With its concise coverage of concepts and numerous practical examples, PHP and MongoDB Web Development Beginner’s Guide is the right choice for the PHP developer to get started with learning MongoDB.

Preface

Problems with using MongoDB and RDBMS together


Before you start building your next web application, powered by a hybrid data backend of MongoDB and MySQL (or any other relational database), you should consider some of the problems you might face.

  • Data consistency: If you use MongoDB as a cache-tier on top of a relational database, you will need to keep it consistent with the changes in the underlying data. You can run background processes that are fired at a certain time, and update the stale data in MongoDB. A more elegant solution would be to define callback methods in the data access layer, which will automatically update the MongoDB data every time you insert/update/delete something in the tables.

  • Complexity of the software architecture: From the application developer's point of view, having both MongoDB and an RDBMS as the data backends increases the complexity of the code. This is because he now has to provide and support two separate data access layers, one for the MongoDB database...
