complexity in developing, deploying, and managing business-critical MySQL applications. • Achieve database high availability using MySQL InnoDB Cluster and MySQL InnoDB ClusterSet • Build, deploy, and • Protect sensitive data using encryption, key generation, and digital signatures • Block database attacks such as an SQL Injection with MySQL Enterprise Firewall • Implement policy-based auditing auditing compliance to existing MySQL applications with MySQL Enterprise Audit • Improve database performance and availability with MySQL Enterprise Monitor • Use relational tables and schema-less

performance and system value. In the software domain, MySQL Server is a commonly used Relational Database Management System (RDBMS).This whitepaper clarifies how today's data centers combine SSDs and MySQL Processing Performance Council (TPC) [www.tpc.org]. It is widely used and well understood, which enables database administrators to quickly correlate quoted TPC‐C results to their specific application. TPC‐C simulates CPU bottleneck, we tested two types of database servers: Dual Socket (12 core) and Quad socket (28 core). Dual‐socket (12 Core) configuration Database Server (Client) Load Generation Server

MySQL是一个关系型数据库管理系统，由瑞典MySQL AB公司开发，目前属于Oracle 旗下产品。MySQL是最流行的关系型数据库管理系统之一，在Web应用方面，MySQL 是最好的RDBMS (Relational Database Management System，关系数据库管理系 统）应用软件之一。 MySQL是一种关系数据库管理系统，关系数据库将数据保存在不同的表中，而不是将 所有数据放在一个大仓库内，这样就增加了速度并提高了灵活性。
