Finished my Software Engineering specialization while ago, and also the paper I had to deliver for conclusion.
The rule that college imposed was that should have a maximum of 15 pages, so it got very sintetic.
My intention was to pass over databases and in the end, talking about relational and non-relational..
This week I had a SELECT a little more complex to execute, that I needed to concatenate a string with a field value of the own table that I was selecting. I didn’t wanted to split my sentence in two on PHP, I was convinced that should have a way to do that without depending on PHP to pass a field value to a second query.
