Open Refine (previously Google Refine) is a data cleaning software that uses your web browser as an interface. This means it will look like it runs on the internet but all your data remains on your machine and you do not need internet connection to work with it.

The main aim of Refine is to help you exploring and cleaning your data before you use it further. It is built for large datasets – so don’t worry as long as your spreadsheets can keep the information: Refine can as well.

There are many different ways of achieving high availability for MySQL. This Guide introduces DRBD (Distributed Replication Block Device), one of the leading solutions for MySQL HA (High Availability), offering users:

An end-to-end, integrated stack of mature and proven open source technologies, fully supported by Oracle;
Automatic failover and recovery for service continuity;
Mirroring, via synchronous replication, to ensure failover between nodes without the risk of losing committed transactions;
Building of HA clusters from commodity hardware, without the requirement for shared-storage.

The whitepaper covers the core underlying technologies supporting today’s most successful web services including:
- MySQL Database
- MySQL Cluster
- MySQL Replication
- Caching with Memcached and Redis
- Big Data with Hadoop
- NoSQL APIs
- Geographic Redundancy
- Hardware Recommendations
- Operational Best Practices

By leveraging the best practices identified in this Guide, you will have a starting point to building the next web and mobile phenomenon.

This paper looks at the various types of data that modern businesses need to manage, examines the reasons why a model-driven approach to data management is necessary, and outlines the benefits such an approach provides. It also highlights how Oracle’s MySQL Workbench can be an indispensable aid in the hands of experienced data modelers, developers, and DBAs who are tasked with managing the complex data management infrastructure of a dynamic and growing business.

Selon une étude du cabinet EY, seulement 17% des entreprises françaises ont entamé une démarche d’exploitation des données massives.

This guide will walk you through understanding the MySQL security model, post-installation, nd securing user accounts and replication.

MySQL does not have a built-in command to execute shell commands, as Microsoft SQL Server does. Nonetheless, I will show you how SQL injection can allow anyone to run arbitrary commands using standard features provided by MySQL.

First of all, I will give you a brief description of SQL injection. Then I will present you with a couple of less known methods that exist in MySQL, which I will use to open a backdoor to a webserver. I will use 2 built-in MySQL commands - one that writes arbitrary files and one that can be used to read arbitrary files. After that I will describe webshells and the attack itself.

This Guide is designed to assist Developers, Architects and DBAs in navigating the complex waters of HA. It presents:

A methodology for selecting the right HA solution to meet Service Level Agreements;
A tour of the leading certified HA solutions for MySQL;
Operational best practices to implement and support HA.
