Mysql关系型数据库管理系统
MySQL是一个开放源码的小型关联式数据库管理系统，开发者为瑞典MySQL AB公司。MySQL被广泛地应用在Internet上的中小型网站中。由于其体积小、速度快、总体拥有成本低，尤其是开放源码这一特点，许多中小型网站为了降低网站总体拥有成本而选择了MySQL作为网站数据库。
MySQL 5.6.24 发布，此版本改进内容如下：
MySQL Enterprise 改进
MySQL 企业版本现在包括 MySQL Enterprise Firewall，一个应用层防火墙，允许数据库管理员基于是否匹配白名单接受的声明模式来决定允许或者拒绝执行 SQL 声明。 MySQL Enterprise Firewall.
新特性和改进
CMake 支持现在更新至 CMake 3.1 (Bug #20344207)
当服务器把初始 “starting”信息写入错误日志时包括其版本号信息 (Bug #74917, Bug #20052694)
ALTER TABLE did not take advantage of fast alterations that might otherwise apply to the operation to be performed, if the table contained temporal columns found to be in pre-5.6.4 format (TIME, DATETIME, and TIMESTAMP columns without support for fractional seconds precision). (Bug #72997, Bug #18985760)
avoid_temporal_upgrade controls whether ALTER TABLE implicitly upgrades temporal columns found to be in pre-5.6.4 format.
show_old_temporals controls whether SHOW CREATE TABLE output includes comments to flag temporal columns found to be in pre-5.6.4 format.
Statement digesting as done previously by the Performance Schema is now done at the SQL level regardless of whether the Performance Schema is compiled in and is available to other aspects of server operation that could benefit from it. Bug #18304086, Bug #20015246.
