what is a database?
earlier than i’m able to solution what mysql approach, i must provide an explanation for what a laptop “database” way.
essentially, in which computers are concerned, a database is just a collection of records. specialised (or “specialized” in us english) database software, like mysql, are simply applications that helps you to keep and retrieve that information as successfully as feasible.
a touch analogy may help make it clearer why we use specialised database software program. reflect onconsideration on the files saved to your pc. if you had been to store all of your documents using a (mind-lifeless) file naming scheme like “1.doc”, “2.document”, “three.document”, … “nine,999,999.document” (and many others), you will ultimately face a hassle of finding the right report if you’re seeking out a specific file. for example, if you’re looking for a enterprise inspiration you made some time ago to xyz business enterprise, which document need to you open? one way is to sequentially take a look at every unmarried file, beginning from “1.doc”, until you get the right records. but that is glaringly a rather inefficient method of getting the proper report. and it is commonly the result of an inefficient technique of storing your statistics (ie, saving your files) within the first area.
now, that is of course a ridiculous example. i suggest, no one i know saves files with names like these, and even in that case, there are many search software program that will let you locate the appropriate record without your having to manually open every single one in sequence. but it serves to make the point that once you’ve got quite a few statistics, if you don’t have an awesome device of setting up it, locating the correct piece of information is a very time eating operation. and it turns into greater time eating as the quantity of facts grows.
a database application is a kind of pc software program this is designed to handle lots of records, however to save them in this type of way that finding (and accordingly retrieving) any snippet of statistics is more green than it might had been if you surely dumped them willy nilly all over the place. with one of these database software, if you (say) maintain a listing of customers and their transport addresses, getting into and retrieving data approximately your one millionth customer will no longer take a good deal longer (if in any respect) than coming into and retrieving facts approximately your 1st purchaser.
