Hello. I have a question for your expertise. I currently have a mysql database with two tables, one with static information about tanks that will always stay the same (height, diameter, capacity, etc.) and another table with dynamic information that will change regularly (levels, products inside), approximately 3 times a day. at 7, 3 and 11. My question is how do I make the dynamic table work with dates and times? Is it better to have one giant table or generate a new one for every date and time. Also, what would be the best PHP functions to use to do the dates and times. Also, I am using the tank number (varchar) as the primary key for each database as of right now. Thank you for your help.
