If i were required to store about 150 vehicles in a database that kept track of everyday of the week for a week in advance at what times those vehicules were busy down to the minute would it be ok to create a box for every minute of the day and fill them in based on a form i created in php. This would be about 2400 boxes for every vehicule. which is 360000 boxes. Bear i mind ive had no training to handle large scale databases and its a personal hypothesis.
