MySQL

URL

: http://www.mysql.com/

license : GPLv2

platforms : Unix, win32, win64, MacOS X, i5/OS

Pros

  • Easy to install and administer
  • Support for many SQL Features (v5.0 and up):
    • Good compliance with SQL standards
    • Foreign Keys (using InnoDB)
    • Stored Routines
    • Views
    • Triggers
  • Subqueries (as of v4.1)
  • Partitioning (as of v5.1)
  • ACID compliant (InnoDB and NDB storage engines)
  • Character set support
  • Built-in Replication
  • Many administration tools from third parties
  • Widely deployed
  • Regarded as being fast
  • Modular storage engines and interesting clustering features

Cons

  • Early versions (v4.1 and earlier) have the reputation for only basic SQL support (entry-level SQL 92) and deviations from the standards. Many interesting features (views, triggers,..) are included in the latest version (5 and above), but are missing in prior versions. Check SQL Modes for making MySQL more strict.

  • Some gotchas for MySQL v4.1 and earlier.
