This post initiates a series about databases. On a first part I will write about the database theory leaving for a later occasion other subjects like SQL.

The theoretical part will consist in what is a database and a database management system (DBMS), in focus on this post, what is a relational database, some terminology to be aware and finally the process description of a database design.

The goal with this set of posts is not to write in detail about subjects that you can easily find on the web, but is to structure some concepts that we then to neglect during our daily activities and that end to be decisive to our project success.
