Design And Implementation Of Construction Equipment Lease Information System

Construction equipment leasing industry charges certain cost to meet its own demands.The development of construction equipment leasing business is carried out based on equipment data,customer data and other basic data,businesses process ability is affected by data process efficiency.The development of information system can provide technical support for equipment leasing company,thus to enhance business process efficiency.A construction equipment leasing company in Henan province is selected as background in this dissertation for the development of equipment leasing information system.Information state of this company is analyzed,and actual demand for information system is acquired.According to business scope,border of this information system is determined.According to users' duty and different requirement for information system,system users are divided into several kinds of participants which include system manger,customer,counterman and so on.According to the sequence of total design,detail design,system functional analysis model is established,and participants' use case model is acquired too.Business process model is designed based on business process rules.The system is divided into several functional modules,and functions in every module are determined.J2 EE is selected as system development technical platform,the framework combination of Struts and Hibernate is used for circumstance establishment.According to MVC design pattern,the system is divided into three layers of Model,View and Control based on technical that used in this project.Roles of every layer are determined,and calling sequence between different layers are designed too.Database structure for information system is designed;database conceptual model and relation model are acquired.Based on database design model,database tables are created.Business classes and methods are designed for every function,and calling sequence between different classes are designed too.The system is implemented by IDE technical tool,and functional interfaces are designed too.On the basis of system deployment,system running results are acquired.The development of construction equipment leasing information system enhanced business process efficiency,and ensured business process orderly.
