| The government information publicity system based on J2EE framework, to realize the standard object oriented design patterns.System development to loose coupling as the development train of thought guidance,the presentation layer, business logic layer and persistent storage layer three layer design architecture, considering the development efficiency, performance and application of ductility.The government information publicity system development in the use of innovative design of data warehouse concept, the use of domestic analysis database as the accelerating engine, through business division will be transactional operation and analysis of operation to do an effective classification, ensure system operation in the years after the data expansion can still guarantee the user query response speed.I am mainly responsible for the data warehouse architecture of the overall design of storage process developmentIn in the project,and the directory management, applying public information management part of the code design.The government information publicity system use J2EE platform architecture design, The design adopts a multilayer architecture, the system is clearly divided into the presentation layer, application management layer, data layer, information collection layer and network layer, Database design use the formal design of data warehouse model, and adopt star type model design. The government information publicity system transaction processing operation and statistical analysis of separate operation, the thermal data is stored in the database of the traditional relational data, and use of a row of the memory of the database as the data warehouse to store information and statistical analysis.Government information system have been running for three years, and appearanced of real data expansion, because of the original account, so the system still run intactly and quickly. All statistical analysis of query speed remains less than 1 second response time. |
