Hi.. I need to create a DAILY TIME RECORD SYSTEM for time in and time out of the students in the library. The system must be able to calculate the total time of a certain student whenever he/she wants to. The students have their own identification ID NUMBER when they time in and time out. In connection with this, I need help from you who knew a lot about DATABASE or JAVA. I planned to use database for the said system and connect it to PHP. However, in order for me to fulfill this, I really need your help to give me some sample of DATABASE for the said planned DAILY TIME RECORD SYSTEM. I hope you will hand your help to me. I will greatly acknowledge your help and so your site. Thank you!.
