The Story: Behind MySQL


            If you’ve had even the slightest bit of experience with rational databases, you’ve probably encounter the word MySQL: It’s a high-performance, multiuser relational database management system that is today the de facto standard for database-driven software applications, both on and off the Web.

Designed around three fundamental principles---speed, stability, and ease of use---and freely available under the GNU General Public  License, MySQL has been dubbed “the world’s most popular open-source database” by its parent company MySQL AB and with good reason. Official statistics reveal over five million sites are creating, using, and deploying MySQL-based application, with more coming into the fold on a daily basis. You may even have heard of some of MySQL’s customers: do the names Yahoo!, Google, Cisco, NASA and HP sound familiar?

History

              The MySQL story hasn’t always hasn’t been about rocketing growth rates and high user satisfaction ratings, however. MySQL has an interesting history, with roots going back to 1979, when Michael “Monty” Widenius created a database system named UNIREG for the Swedish company TcX. UNIREG didn’t work for TcX on account of performance issues, and TcX began a search for alternatives. They tried mSQL, a DBMS created by David Hughes, but when that attempt also failed, a new approach was called for. Thus, Widenius decide to create a new database server customized to his specific requirements, but based on the mSQL  API (to simply porting applications between the two). That system, completed and released to a small group in May 1996, became MySQL 1.0.

The New Internet World


A Global Perspective on Freedom of Expression, Privacy, Trust and Security Online A contribution to: The Global Information Technology Report 2010–2011 Worldwide diffusion of the Internet is focusing debate around values and attitudes that are likely to vary across cultures, particularly around online freedom of expression, privacy, trust, and security. These are prominent topics of discussion amongst leading Internet stakeholders, such as private and public sector members, governments, policymakers, and the media. However, we know relatively little about the opinions of users around the world. How do users see these issues, and how do they experience the impact of the Internet in these areas? This study reports the results of a survey of over 5,400 adult Internet users from 13 different countries. The online survey was conducted by the Oxford Internet Institute (OII) and INSEAD, in collaboration with comScore. It was designed to better understand cross-cultural differences in user behaviour and attitudes, focusing on the core Internet values of freedom of expression, privacy, trust, and security.

The Internet is a global system of interconnected computer networks that are set up to exchange various types of data. This "network of networks" connects millions of computers, including those in academic, business, and government networks, transcending geographic and national boundaries. It is made possible through the merging of computer technology with technologies used by the media and telecommunications industries.
The Internet connects information resources and provides various services, such as electronic mail, online chat, file transfer and file sharing, online gaming, and the inter-linked hypertext documents and other resources of the World Wide Web (WWW).

The terms Internet and World Wide Web are often used in every-day speech without much distinction. However, the Internet and the World Wide Web are not one and the same. The Internet is a global data communications system. It is a hardware and software infrastructure that provides connectivity between computers. In contrast, the Web is one of the services communicated via the Internet. It is a collection of interconnected documents and other resources, linked by hyperlinks and URLs
