Project management system

Abstract

The invention provides a project management system which comprises a presentation layer, a business layer, a service layer and a data layer. Information is sequentially transmitted and is fed back through the presentation layer, the business layer, the service layer and the data layer. The presentation layer, the business layer, the service layer and the data layer are developed by the adoption of the .NET technology. The uniform standard protocol is adopted in interfaces of modules in the presentation layer, the business layer, the service layer and the data layer. According to the project management system, due to the SSH basic structure, cohesion conflicts which possibly happen are effectively avoided; the service layer and the data layer have higher stability; when the specific modules are developed, a development team can conduct independent research and development according to independent functional requirements.

Description

technical field [0001] The invention relates to an engineering management system. Background technique [0002] The management of construction projects is a complex system operation. In the process of management, it often needs to process a large amount of data quickly. On the whole, the government's management of construction projects involves a wide range of areas, and the needs of various departments are also different. Therefore, if each If a government department independently designs a system, the cost is too high, and various problems are prone to occur in the connection, resulting in low efficiency and affecting the final effect of the construction project. [0003] In the prior art, there is a technique of using computer technology to manage construction projects, such as the Chinese invention patent "A Project Management Monitoring System and Method (Publication Number: CN101551882A, Publication Date: October 7, 2009)" discloses a A system based on handheld termin...

[0002] The management of construction projects is a complex system operation. In the process of management, it often needs to process a large amount of data quickly. On the whole, the government's management of construction projects involves a wide range of areas, and the needs of various departments are also different. Therefore, if each If a government department independently designs a system, the cost is too high, and various problems are prone to occur in the connection, resulting in low efficiency and affecting the final effect of the construction project

[0003] In the prior art, there is a technique of using computer technology to manage construction projects, such as the Chinese invention patent "A Project Management Monitoring System and Method (Publication Number: CN101551882A, Publication Date: October 7, 2009)" discloses a A system based on handheld terminal application servers to manage and monitor projects. Obviously, the system adopts an old-fashioned fixed model, and the scalability is not high. If it is actually used, each government department that needs to manage projects needs to design each part separately, and It also needs to be extended according to its own needs, which does not solve the above-mentioned problem of difficulty in connecting the various departments

[0004] Another example is the Chinese invention patent "Control and Management System for Engineering Construction Project Contracting (Publication Number: CN102955982A, Publication Date: March 6, 2013)" which discloses an enterprise-level distributed architecture system based on the .NET standard. The system makes full use of the advantages of .NET, realizes business distribution and control integration, and adopts an object-oriented architecture, so that each part can be independently designed, implemented and tested, thus providing good reliability for project supervision. Extended system, but there are still serious defects in the actual application of the system: the access to the database is direct access to each part, which leads to the possibility that similar or even the same data between different departments will exist repeatedly, and in order to avoid The occurrence of this kind of situation will inevitably lead to the programmers of various departments must be coordinated with the programmers of other departments, especially for the data access structure must be coordinated, and the actual realization of this will inevitably require all departments to jointly discuss a unified Obviously, under the current national conditions in our country, it is almost impossible to achieve this, so the system can only be applied to a single government department in the end. As a result, the system seems to have made a breakthrough in technology, but in fact it still has no make any substantial progress
