Design And Implementation Of The Service Procedure Of Net Software Dog Based On Object Oriented

With rapid development of electronic computer application, use of computer software bring enormous social benefit and economic benefits. But there is the behavior of duplicating illegally in a large amount, plagiarizing and selling cheaply software which others design at the same time. Indulge software pirating will break down software industry and be unfavorable to national economy development finally.Then, how to prevent from software pirating. At present, main software protect technology as follows: sequence number protection, time restriction, Anti-Debug technology, the floppy disk protection, encrypt key etc.. Net software dog, apply mainly among the network environment, prevents application program in network from pirating and controls the number of software licence of customer end among the network environment effectively at the same time. In addition, whole network only need to use one net software dog, that reduces the cost of encrypting. So that net software dog is very meaningful.This text introduces the developing stage and composition, analyzes the advantage, various function, software and hardware system and system demand in detail. This text introduce Object Oriented design program developing stage and composition, and the advantage of using Object Oriented which designs program. At last, we use Object Oriented design program method to analyze and design the service routine of net software dog.The key part is that on the basis of Object Oriented analyze and design designs the service routine system of net software dog. This text applys with UML technology of Object Oriented to analysis and design, use UML describe a series of view model of the service routine of net software dog in the design processes. Describe system with class diagram, object diagram in terms of static behavior, describe system with state diagram, sequence , collaboration diagram and activity diagram, and describe target in system how to how mutual each other in different time point, finally write the code and test. And in analysis and designing process employ design pattern principle, raise design software reusability and maintainability. Finally, the thesis look forward to the future development of net software dog, many products of the same corporation licence managed, apply in identity authentication, e-commerce etc.
