MySql is a database management systems.
People think and feel it is something over complicated, yet it can be as simple as understanding punctuation for some.
As with this site we have hundreds of smiles, quotes and anything else that needs adding by MySql far quicker then inputting this by hand on a web site.
As MySql is information and a way to access all of that.
So by writing out the same line it uses for one task, copy that and make a couple of hundreds bulleted lines with numbers to begin, add the line of code on every line and you have what would have taken ages, sitting there adding by hand doing.
Then that MySql information is accessible by our different web systems to supply that information to make web systems.
The only difference between one system and another really is punctuation and what each point is there for.Mysql-Speed-Indexing
