List of Best Practice MySQL Data Types

Question

Is there a list of best practice MySQL data types for common applications. For example, the list would contain the best data type and size for id, ip address, email, subject, summary, description content, url, date (timestamp and human readable), geo points, media height, media width, media duration, etc

Thank you!!!

Answer 1

Money: Use the Decimal data type. Based on real-world production scenarios I recommend (19,8).

EDIT: My original recommendation was (19,4); however, I've recently run into a production issue where the client reported that they absolutely needed decimal with a "scale" of "8"; thus "4" wasn't enough and was causing improper tax calculations. I now recommend (19,8) based on a real-world scenario. I would love to hear stories needing a more granular scale.
