Even a development engineer, but also of MySQL users, but in the understanding of the principle of one system module later, again to use it, the feeling is completely different.
When the command to write a line of code in the database, you can think of how it will perform on the database side, its performance is how, how to write our highest-performance applications that access the database. Further, the data processing which allows the database system performance will be better to do, what to do data processing performance will be better in the cache, and my heart will be more clear. In the build table and build an index, I will be more conscious to do considering the future of query optimization, such as determining whether to use incremental primary key, how to select the primary key columns, and so on.
So the system needs to learn mysql, formation of a learning network rather than only knows fragmented knowledge. A business developer might use two or three years MySQL, but also those who may not know they have been in use "best practices" Why is the best.
After reading these need to output your mysql knowledge network.
