Reseach On Marching-on In-time Scheme And The Fast Algorithm Of Time Domain Integral Equation

With the revolution of information technology, computer and internet growpopularity and development rapidly, and information technology plays a more and moreimportant role in production activities. Information technology has become a coresource to promote the modern enterprise, and to realize the leap forward development ofenterprises.Looking back more than thirty years history on enterprise information constructionin our country, the construction of information system from scratch, covering all aspectsof the enterprise operation, and has achieved obvious achievement. However, in theearly days of enterprise informatization overall planning is absence, and theconstruction of information systems is usually faced to a particular department, it isfragmented and self-contained. IT infrastructure deploys excessively, system isinefficient and management costs increasing every year. Cloud computing based on the"resource sharing, distribution according to need" concept, it breaks the physicalbarriers of hardware through virtualization technology, it integrates IT infrastructure asa virtual resource for unified management, allocate resource for every system accordingto the different needs, and adjust resource in accordance with dynamic load. The use ofCloud computing greatly improved hardware efficiency, reduced management costs,shorten the development cycle, and it provides a new solution to solve many challengesin enterprise informatization.This paper takes the problems in enterprise informatization as background, sudiesCloud computing-based enterprise informatization. Papers analyzed the background,content, models and key technologies of cloud computing. Take the informatization ofChina Railway Modern Logistics as an example, pointed out the existing problems inthe informatization construction at the present stage, put forward the overall structure ofthe cloud platform, realize the migration of existing systems, and analyze the effect ofthe program. Analysis of the demand for customer relationship management system,analyzes the function module of the system, made detailed design and system databasedesign. Finally, use the JAVA language to realize the system, and showed the systemrunning effect.
