XXXXXXXXXXXX 合同与项目管理系统的设计与实现
Contract and project management system takes a 3-Tier Data Architecture on
basis of B/S structure and J2EE platform. The 3-Tier Data Architecture includes:
Presentation Layer 、 Business Layer 、 Persistence Layer. Presentation Layer
responsible for completing the data show, achievement of the collection of data and
the show of the resulting data on the page; This layer carries out presentation layer—
open source framework Struts2 what based on MVC pattern construction to build,
view adopt JSP to achieve, with CSS and JQuery to create a good user experience
environment. Business Layer responsible for handling business logic, using JavaBean
to achieve. Persistence Layer responsible for the interaction with the database; the
main achievement of operations about entity data add, delete, change and other
operations; using open source persistence framework MyBatis to achieve, while
incorporating DAO framework to reduce the coupling; It uses MySQL database to
store data.
Dissertation completed the design and implementation of contracts and project
management system, describing detailed design, contract and project information
stored backed up, destroy the function of the system background, technical
background, needs analysis and the overall system architecture, and the design of the
database.
Key words: Contract Management J2EE B/S three-layer architecture Struts2
