‫We've learned so much so far, we know what rescue will is, what a query is, we even know why we call

‫Escuela declarative language.

‫But what we don't know is the history of school.

‫How did a school come to be?

‫Where it all start?

‫Well, don't worry.

‫I've mapped it all out for you in the small section on the history of school.

‫So the original name of school is sequel and you'll often hear these used interchangeably.

‫Do you sequel?

‫Some people will call it sequel.

‫Some people call it a sequel.

‫Well, sequel was the original name and it stood for structured English query language, but it had

‫to change its name due to copyright conflict.

‫So they changed it back to ask you well structured English query language, and that's why you'll hear

‫both names used interchangeably.

‫Now, it was invented in the early 80s and it's still hold strong today as a standard for acquiring

‫and manipulating data.

‫But how did it come to be and who was behind it?

‫Well, in the 70s, a programmer from IBM named Edgar Chod wrote a paper that set the standard for databases

‫and school.

‫His paper was called A Relational Model of data for large shared data banks.

‫What a long name, but that's not the important part.

‫You know, he wrote this paper.

‫But what was amazing is that it inspired two other developers from IBM, Donald Chamberland and Raymond

‫Boyce, to implement his vision.

‫They took his paper and they created the very first version of Eskil, both the language and the software

‫to create and manage databases.

‫And so to this day, Eskil, reign supreme and ask you all is known to be a language to manipulate and

‫manage databases, and they laid the foundation for it.

‫Now, there were specific reasons for which this paper was written.

‫And when we dive deeper into why we use databases, this will become clear.

‫But for now, the important part is to know that these two fellas from IBM, based on his ideas, wrote

‫the original version of school.

‫And what's even more fascinating is that school is a language that is standardized.

‫What do I mean by that?

‫Well, let's take a closer look at what standardization is.
