Analysis And Design Of "BBT" Service System

The so-called "BBT" service is used to provide the National Immunization Policy and the knowledge related to maternal health, childcare, disease prevention, and other relevant information by sending short messages to service subscribers, so that the subscribers are able to lead a more healthy life. The main functions of this service are as following:the Immunization Secretary, the Vaccination Reminder, the Maternal Health Reminder, the Maternal Health and Childcare knowledge dissemination.In this article, the relevant background knowledge is introduced first, and then based on the analysis result of market needs, BBT service system is described in detail from many aspects, including requirements analysis, design, function of each module, database structure. At the end, the test environment/strategy/results and deployment of BBT service system are mentioned.In the background knowledge section, the industry information, the current status of Health System Information, the BBT service related knowledge, Short Message Service technology and Value-added telecom business related knowledge are introduced.In the requirements analysis section, through analyzing and repressively decomposing the needs based on the result of research work on BBT service, the key functions that BBT service should provide are analyzed. Meanwhile, the non-functional and operation/maintenance requirements are briefly discussed as well, such as the system performance requirement and system security requirement.In the design section, the interfaces through which BBT service system interacts with the external entities are analyzed according to the external environment analysis for BBT service system. Based on the necessary functions derived during the requirement analysis phase, the static structural design and dynamic design for BBT service system are provided through some cases. Meanwhile, the implemental algorism of main function modules is introduced, and the key issue encountered during the system design process is discussed and proposed a solution. In addition, the database structure is described. In the test and deployment section, the test environment, test strategy and related test result are described. Besides, the BBT deployment in the real environment is simply introduced.At the end of this article, the author's work in the requirements analysis, design and test process is summarized.
