The document discusses MySQL, the most popular open-source database in the world. It covers how MySQL can provide high availability through replication and monitoring. It also describes MySQL Enterprise Monitor which provides a consolidated view of MySQL servers and reduces risk through query analysis. Key architectures like replication topologies, application partitioning, and sharding are explained to improve performance and scalability. An example of Wikipedia's large-scale use of MySQL is provided.

12. Application Partitioning
• Significantly improves performance and scalability, but the
application must be designed to implement it
• Vertical Partitioning - 1:1 tables to reduce the size of rows,
tables and indexes
• Horizontal Partitioning - 1 table split on multiple tables with
different rows
• Tables can be split on multiple servers

Many choose MySQL Enterprise because it offers a new and different paradigm of database management. One key technical differentiator between MySQL and other database platforms &#x2014; whether they are proprietary or open source &#x2014; is the pluggable storage engine architecture of MySQL.\nThe MySQL pluggable storage engine architecture enables a database professional to select a specialized storage engine for a particular application need while being completely shielded from the need to manage any specific application coding requirements. The pluggable storage engine architecture provides a standard set of management and support services that are common among all underlying storage engines. The storage engines themselves are the components of the database server that actually perform actions on the underlying data that is maintained at the physical-server level.\nThis efficient and modular architecture provides large performance and manageability benefits for those wishing to specifically target a particular application need &#x2014; such as data warehousing, transaction processing, high-availability/cluster situations, etc. &#x2014; while enjoying the advantage of utilizing a set of interfaces and services that are independent of any one storage engine.\nThe technical advantage of MySQL Enterprise is clearly evident in this respect, as unnecessary overhead is avoided when only certain engines are chosen for application use.\n
Point to make:\n\nMySQL Monitoring & Advisor Service = &#x201C;Virtual MySQL DBA&#x201D;\n\nThere are 3 main features, each with business rewarding features&#x2026;\n
