Statements Generated. Net-based System Design

As an indispensable portion of Enterprise information plat, report is one of the important ways in collecting and analyzing the correlative information, while it's essentiality and universal application have been visualized day by day in people's life. C#, a complete Object-Oriented computer language, is the main language used in the system.The project request and the shortcoming of report system nowadays, they make us use full-developped mode to develop system. The System uses the Unified Modeling Language to construct various model, which communicates structure to be designed with system action. Some design patterns adopted in the code make system extensible and reused. The xml format used in the system file as memory medium solves the problems which convert to other format.The system designs gingerliness a few structures that accomplish the diversification about the head of report, unify various of data source in the body of report, exchange information with user, read and write the report file and print the report. Duing the system designing, we should do the best to ensure the coupling about objects low-lying and do the best to box the object which is changed easily, which can sure system extensibility, flexibility and pluggability.
