With the development of computer technology, many things can be done automatically
with the help of software.
From the beginning to help with the help of computer can now get the simple calculation to
scheduling complex machine instructions, arrange the computer to help us to realize the
complex logic, automation of complete many time-consuming work, and you can use the
network to realize long distance and crafty management, and the data is more accurate than
artificial, also with a variety of advantages, the network system of check on work attendance
has been completely can replace the previous artificial statistics attendance information, and
you can also use cross-platform use cell phones and computers.
This system adopts B/S architecture, which can use the browser to use the system without
worrying about the limitation of the operating system. Centering on the core business of
attendance, it realizes the modules of attendance check, attendance data statistical analysis
and so on.
Keywords: attendance; B/S architecture
