Databases and SQL

The answer to the problem Node left you with — data that survives, for more than one person at a time.

Node and Express ended on an honest admission: a JSON file works until two requests arrive at once, and then it quietly loses data. This course is the answer to that. It teaches SQL the way the rest of the track teaches…

What you'll learn

Explain what a database gives you that a file cannot, in terms of concurrency and guarantees
Design a table with the right types and constraints, and say what each one prevents
Query with SELECT, WHERE, ORDER BY and LIMIT without guessing
Count and group data to answer questions about it, not just list it
Join tables, and predict which rows a join keeps and which it drops
Insert, update and delete safely, and never run an UPDATE without a WHERE
Use a transaction so that two changes either both happen or neither does
Add an index for the right reason, and explain what it costs
Change a live schema through migrations rather than by hand
Query from Node with parameterised statements, so SQL injection is impossible
