When it comes to getting into the interesting software sector related to programming and development, many focus on working with databases. Mastering this area is not easy for many, while for others it is something truly exciting, where SQL plays a key role.
I’m sure this is a term that many of you are more than familiar with if you are used to technology. When we talk about SQL, we are actually referring to a language for structured query in programming that focuses on allowing us to store and process information in one relational database.
Here, information is stored in the form of tables where we also add a series of data attributes and relationships between values. Thus, through the SQL statementswe will be able to carry out all kinds of operations with the information that we store in the databases. SQL is also very useful for optimizing the performance of these important elements.
The complexity of the database we create will depend on our needs or how far we want to go into this sector. That is why we are going to show you a series of free courses that you can follow without spending a single euro, all in video format, through Google’s popular streaming service, YouTube.
