MySQL, the most popular open-source database, offers the power ofa relational database in a package that's easy to set up andadminister, and Learning MySQL provides all the tools you need toget started. This densely packed tutorial includes detailedinstructions to help you set up and design an effective database,create powerful queries using SQL, configure MySQL for improvedsecurity, and squeeze information out of your data.

After covering the basics, the book travels far into MySQL'ssubtleties, including complex queries and joins, how to interact withthe database over the Web using PHP or Perl, and importanthouse-keeping such as backups and security.

Topic include:

  • Installation on Linux, Windows, and Mac OS X
  • Basic and advanced querying using SQL
  • User management and security
  • Backups and recovery
  • Tuning for improved efficiency
  • Developing command-line and web database applications using thePHP and Perl programming languages

The authors, Saied Tahaghoghi and Hugh E. Williams, have careers inacademia and business, and share a keen interest in research intosearch technologies.
