Project Overview
Project Background
Guangdong Provincial Communications Department is an important function of the Guangdong provincial government departments.In recent years, the Guangdong Provincial Communications Department leadership attaches great importance to information technology work, have put a lot of manpower and financial resources to build information systems, construction of a number of business management systems and file management system and other office support system, and internal communications departmentconstruction of high-speed network system, to develop and improve the level of information to make a lot of contributions.But information technology is currently in Department of Transportation there are still some pressing problems, mainly in: Provincial Communications Department in the Office of all aspects of information technology has not yet formed a unified planning, construction of existing information systems using different dataformats, different system platforms, systems can not be a good information exchange.Office information systems that not all form an organic whole, affecting the efficiency of the system play.
Project objectives
Structural integrity of the Guangdong Provincial Communications Department based information platform for Guangdong Provincial Communications Department Information System provides the core functionality, to achieve consistency of system functions; Integrated Communications Department, the application subsystem, making it an organic whole; establish a uniform trafficOffice of the basic data standards, data integration system and implement a unified data management, data consistency; provide good expansion interface, to achieve good system scalability.
Applications
Guangdong Provincial Communications Department within the offices.
User Object
Guangdong Provincial Communications Department within all staff.
Technical Features
In the system used in the design Browser / Server architecture and seamless use of multi-source data integration, knowledge management and other advanced technology, and popular e-government information systems, with high advanced technology, and reflectMany features, including:
Good compatibility
Data management system is platform independent, multi-source data through the seamless integration of technology with a variety of heterogeneous data sources connected to a good solution to the problem of integration with related systems.
Powerful scalability
System uses the B / S structure and function of the core layer structure, the core functions and the application layer separation, the ability to easily extend the core functionality to improve the function of the whole system.
Powerful system scalability
Core functions of the system open and to provide standard data and function interfaces.On standard data and function calls can easily construct new business applications.
A powerful system security
In addition to the usual information systems security policy, the system also uses CA authentication and encryption technology, PDF documents, greatly enhancing the system security.
In addition, this system also structural stability of the system of process control, support for remote office has outstanding performance.
According to user requirements, the system uses the Lotus Domino R5 based communications platform, and DECS, LEI (Notes Pump) or LS: DO flexibility to implement Lotus Domino databases and relational database integration, existing business can choose a mountor more of the ways to achieve integration with existing business systems.Lotus platform using common development tools, development tools and a combination of programs.System-based development tools to Lotus, Lotus environments can take advantage of the function.Using Java, avascript so can be easily developed for Internet and Intranet.
Systems architecture
In general, a complete information on the overall structure of traffic engineering can be divided into four levels, they constitute an organic whole, the structure of relationships, such as the general framework shown in Fig.
System for the four levels: basic level, the platform layer, application layer, and comprehensive professional decision-making.Base layer is the physical network, including information transmission, the traffic information database based on information infrastructure, including transportation; platform layer is constructed based traffic information system platform, is the core of the whole system; professional application layer is a professional business applications framework; integrated decision-makinglayer is the organization and leadership framework.System structure is shown below.
System structure
Posed by functional software system can be divided into four parts: Workflow Management System (WFMS), office automation system (OAS), document management system (PMS), information distribution system (IPS), the structure as shown below:
Figure 5 Guangdong Provincial Communications Department office automation system functional components
Workflow Management System
Mainly for system workflow and information flow control, in accordance with the management regulations and rules, the information route (Route), and control the work process and schedule, control, GIS applications and office automation system procedure calls and messaging.
Office Automation System
Daily office for staff to provide various information processing tools, mainly documents, forms entry, modify, query retrieval, statistical analysis, the output (screen display, print output) and other treatment, is the scope of the traditional MIS.
Document Management System
Mainly for business management staff required to file edit, modify, query retrieval, statistical analysis and other functions, is the basis of information system components.
Office automation systems and business office systems based on the application of the actual situation or scene (scene), is one of specific users, and seamless.
Structural Systems Technology
In software design, will be three models (Three-Tier), according to the data service layer, application logic layer, presentation layer and other levels of structural systems.In specific implementations, will be divided into business functions and institutions application subsystem, the structure shown:
