Today we will analyze a web-based cinema management system, this system has a safety database backup program, easy to use, imitation WIN-DOWS operating mode, allows you to quickly get started.
A web-based project management system for the movie using the framework MYECLIPSE as SSM (MYECLIPSE), the choice of development tools. Web-based management system to a movie project background.

In order to allow the user a smooth landing system to complete the related operations, landing roles you need to set up an account and password for each field.
We summarize the results of the film web based project management system for all data: administrator (admin), user (yonghu), movies (dianying)
