Description
Every data analyst requires data to work. The problem is that they are not always easy to obtain. For some analysts it is daily to work with plain text files such as csv or directly Excel, but the truth is that the real information of the companies is stored in what are called databases.
These databases are, in essence, huge interconnections between tables that relate to each other. In the vast majority of companies this is the dominant paradigm, the relational model. It consists of having the information compartmentalized in different tables so that the information occupies the smallest possible space, but that it can be collected by joining various tables. In addition to this approach, there are also non-relational models, which have a different logic.
