IBM: Applied Data Science Capstone Project. In 1970, he published a groundbreaking paper called the Relational Model for Databases, and this led to the concept that was based on set theory, mathematical set theory, and that abstraction really set the architectural framework for modern database development. That is actually making a request to a centralized database and returning back data from a database, and then formatting it in a web page. The answer is a database. Then there was a company called Sybase, that merged with Microsoft, merged its code with it or there were a variety of different events that I won't cover right now.

So, an application system of an enterprise of a hospital, of an insurance company, of all of these things that might use clinical data, need to be able to access that central store of data even if they were not the system that collected the data. The relationships are stored also in a consistent manner. What does that mean?

The purpose of this course is to introduce relational database concepts and help you learn and apply foundational knowledge of the SQL language. So, each database is a collection of objects primarily something called tables, and other code and relationships as we said in the informatics discussion that database stores data and its relationships.

So, at the beginning of these computing machines evolving really with IBM, International Business Machines, counting machines and through the 1920s, '30s, and into the '40s, they were far more of a computing device not a storage device. So, that had nothing to do with a another computer program that might calculate economic data. This relationships are enforced through referential integrity type of code and also implicit rules that are built into the database.
