Research And Implementation Of Heterogeneous Information Transformation/Transmission Mechanism Based On AMQP

As a low-cost and efficient standard of application-layer transmission protocol, features of AMQP are such as easy to use, high applicability, interactivity, accuracy, safety and reliability. It has been widely admitted and supported by many companies such as Bank of America, Credit Suisse, Goldman Sachs, Microsoft and Red Hat. Nowadays, construction of smart cities has been becoming one of current informationization hotspots. Information for a smart city may come from various operating systems, different databases and a large variety of application software products developed by different development tools, that is to say, it is from heterogeneous systems. It often results in so-called "information islands" that are bottlenecks of constructing smart cities.In order to promote development of smart cities and break "information barriers" among public utilities systems, such as transportation, healthcare, power and water supplies. In this thesis, here, we propose a novel mechanism for heterogeneous information transformation and transmission for exchange and sharing of big data in intelligent healthcare. It covers solutions for such problems as follows:1. For "information islands" problem, we propose a novel transformation and transmission mechanism based on AMQP for heterogeneous information. This mechanism is helpful in solving the problem of information exchange and sharing between two healthcare institutions.2. For transformation problems of heterogeneous information, three partition methods are proposed, such as iterative partition, binary-tree partition and fast pagination. They provide solutions to exchange large XML-based files under constraints of memory. It achieves independency, high efficiency and high reliability.3. For transmission problems of heterogeneous information, the technique of AMQP-based message queues is applied so as to achieve reliable one-way or two-ways transmissions. Compared with simple object access protocol (SOAP), the proposed method achieves more comprehensive features and widely applicability.
