How do you feel about the SQL COURSE?

Question

I never knew what SQL was until today, seems mainly like a second language for database. doesn't seem too hard but also seems like if you say the wrong word maybe your data will be incorrect..

Answer 1

SQL is a fairly well-planned and self-contained language. It doesn't try to do too much. It is great for people who come from the world of spreadsheets. More specifically, it is optimized for tabular data in relational database management systems. Other data models may be better for other types of data. Those are generally referred to as NoSQL (a sort of collective or umbrella term for all non-SQL things). Many people buy only into the NoSQL hype, but the best way to appreciate NoSQL is to intimately understand SQL's limitations.

The SQL course in SoloLearn is a decent fly-by overview. w3schools has a pretty decent tutorial as well. The best way to get the lightbulb-of-enlightenment to go off is to practice joins (etc.) in a real scenario. Mode Analytics has some good practice materials.

Typos are a bane in any language.

My opinion (since the question is about feelings).
