Many web developers consider security a low priority. Security is frequently relegated to the end of the software development life cycle, as little more than an afterthought. Sometimes, software security is neglected entirely, resulting in applications rife with common vulnerabilities. Because such bugs might manifest only under conditions present during an attack, they can be hard to detect prior to such events without knowledge of how the exploitation process works. Using a web application built with jQuery Mobile, PHP, and MySQL, this tutorial shows how many types of vulnerabilities occur along with common methods of exploitation and, most importantly, their respective countermeasures.

Most users at one time or another have dealt with hierarchical data in a SQL database and no doubt learned that the management of hierarchical data is not what a relational database is intended for. The tables of a relational database are not hierarchical (like XML), but are simply a flat list. Hierarchical data has a parent-child relationship that is not naturally represented in a relational database table.

Moving from a relational database, like MySQL, to a NoSQL database, like Couchbase, requires that you change the perspective on your data. In this article, MC Brown explains the differences between structuring data for a MySQL and a Couchbase database. He also discusses how these differences impact your queries

In the first part, we looked at the basic mechanics of MySQL and Couchbase Server 2.0, and compared the ways in which you would model the data, and how the basic queries and lists of records operate, from the MySQL SQL statement, to the Couchbase Server View.

Description of many features in MySQL, which work as advertised, but not as those used to other databases may expect.

This article present techniques to help prevent the gaming of your MySQL-PHP Website. Some of them rely on shutting down scripts; others try to find the humans who are manually executing this behavior.

Take the rapid development of Roo a step further by creating applications to work in the cloud with Cloud Foundry, the first open platform as a service project created by VMWare. Learn more about the environment and then deploy an application into Cloud Foundry using the Roo shell.

This article discusses:
* Setting up automatically updated slaves of a server based on a SQL dump
* Setting up automatically updated slaves of a selection of tables based on a SQL dump
* Setting up automatically updated slaves using data file copy
* Sharing read load across multiple machines

This tutorial describes one approach to using Amazon EC2′s Elastic Block Store (EBS) as a persistent storage mechanism for a production MySQL database server, including snapshot backup and restore.

This two-part article shares some of the lessons learned and take you step by step through a standard process of scaling your PHP-MySQL application based on real-world experiences at Digg, TripAdvisor, and other high-traffic sites.
