A-1 is revised as when deleting user's variations per hour A；
D) it is asked when N platform client computer Client server S erver is sent to additional 1 user of database user table
When asking, server S erver receives request and executes, and number of users is revised as becoming by server S erver according to alteration ruler
Measure A+N；
E) it is asked when M platform client computer Client server S erver is sent to database user table 1 user of deletion
When asking, server S erver receives request and executes, and number of users is revised as becoming by server S erver according to alteration ruler
Measure A-M；
F) server S erver will indicate the change of number of users according to the modification process of variables A in step d) and step e)
Amount A+N-M is stored in memory address；
G) when a client Client, which sends inquiry existing customers to the database user table of server S erver, to be requested,
Client Client calls variables A to obtain active user's quantity, server according to the memory address applied in step b)
Database user table record quantity is that variables A+N-M returns to client Client according to request by Server.
