A problem to ask you a great god
I believe that everyone made certain have received such a reminder: there are six minutes to go to work, don't forget to clock out oh ~ ~
I want to ask next is how to implement this?
I feel I need to check different from each company to work time, even a few minutes to check in advance to the company and several people no time, then send these messages, but this is how to check? Is due to remind or do every day in the memory of a similar poll, query the database per minute??
Like there is a problem, there were 10 w documents in the database, for example, each of the documents making time is different, if you want to achieve is making time and one hour to make people to send information on how to handle? Is only a minute polling the database? Or put 10 data read into memory?
