The Design And Practice Of Conference Registration System

Currently, government departments and social organizations frequently convoke some large-scale meetings, such as Conference on Representatives of the National People' Congress, Chinese People's Political Consultative Conference, Communist Youth League Representatives Conference, All-China Federation of Youth Conference, and Young Pioneers'Representatives Conference etc. the personnel about meeting affairs often need to make statistics about attention, accommodation etc. sometimes, they also need to query the relevant scheduling and basic info on attendees etc. Traditional query and statistic methods are manual, so the efficiency and quality is not high.Developing a set of high-efficient, convenient and maintaining-managing-easy sign-in management system for meetings is very important. On the one hand, this can improve the efficiency and quality for middle and small scale meetings and decrease the waste of manpower and material resources. On the other hand, this can provide the inquiry service of schedule and info for personnel and attendees. It is very important for this sign-in info system of middle and small scale meetings to select a proper development method and network structure. This system adopts OOA to make a analysis and design and implementation. C/S structure is adopted to design applications during development.The first chapter of this thesis describes the background, purpose, meaning and implementation contents of this system.The second chapter detailedly analyzes the system. Firstly, by describing the organization structure of middle and small scale meetings to generally know about that and therefore to make a analysis for the system requirements. On the phase of OOA, the most important is the construction of system model, including object model, dynamic model and functional model. Three models have different importance on different issues. This system emphasizes particularly on the object model. The object model describes the objects of reality and the relationship between them and denotes the static data structure of target system. The steps to construct the object model are: looking for class object, identifying structure, defining attribute and defining service. Generally, we find out as many class objects as possible. So, a mass of incorrect and unnecessary contents are strictly filtered further and the objects which really need its info or its service are saved.On the phase of design, the network structure design, subsystem division and human-computer interface design and data base design of this system are described. In consideration of the practical situation of middle and small scale meetings and the operating requirements of software, two-layer C/S structure development is adopted by the system structure. C/S structure strictly defines the processing range of clients and server, and let clients handle friendly graphical interfaces. Therefore, only data management is handled by server. In the human-computer interface design, the habitual requirements of user are considered adequately, so it is easy to use. Data base design also is important. OODBS is the product in combination with database technology and OOP method. It is a DBMS, so, it has the characteristics of DBMS, such as durability, data sharing, data reliability, inquiry processing and mode modification etc. Also, it has the characteristics of OO, such as class type, packaging/ data abstraction, succession, double loading/ hysteresis binding, categoricalness, object identification, composite object and expandability etc. By this method to finish a consistent, comprehensible, high efficient and correct data base design.In the chapter five, the effects of practical applications are described. The result conforms to the design requirements of system and meets the user requirements by practically testing several times. Finally, the development tool and key technology used for this system are discussed. We choose PowerBuilder6.0 by Sybase as the development tool of this system. PowerBuilder is a GUI development tool, which is easy to use and with powerful functions and can save a lot of time for development activities and therefore increase the tempo of development.
