Relational Database

This lesson introduces relational databases; it, goes over their advantages, uses, and the problems related to them.


Today we are facing a rapid expansion of data-driven businesses, especially businesses that are web-based and have an enormous amount of data being transferred every second. In fact, almost 90% of all data on the web has been created in the last several years. Usually this data has to be stored in a database. However, since every business is different, there are different needs that need to be taken into account when looking at ways to store the data. There are two routes we can take:

  • Relational Databases
  • NoSQL

Further on, you will cover the strengths and weaknesses of both, but it will largely focus on NoSQL databases and why we need to consider them as a solution to our problems.
