Research On The Standardization And Association Mechanism Of DOA's Data Registration Center

In recent years, the development of the Internet and information industry promotes the transformation of the traditional industries and economic structure. In every industry, every function of the field, Internet data generations and interactions are continuous, heterogeneous, massive, and uncontrolled. Part of the public data have been effectively used, and transform into information, knowledge and decision-making. But most of the data became the information island between the industry because of massive heterogeneous data, dynamic and multi-dimensional data, and software system structure, and this kind of data explosion brings hidden trouble and unnecessary development cost.The data oriented architecture(DOA) is proposed to adopt the idea of data oriented, which provides a way to solve the system's information sharing and the function extension of the built system. The thesis is the research of the association mechanism of data registration center which is the core part of DOA.This thesis firstly introduces the related research background at home and abroad, and some theory and technology; then the paper introduces the preliminary design of the data registration center and function combined with the practical application of information education platform project; then the thesis began to study and sort out a DOA based data registration center standards and data-register standard based on several projects above; At last, the thesis starts a system interaction mechanism of DOA, and the interaction mechanism between the data registration centers based on the standards above, including but not limited to the node creation, data registration, synchronization, node link node data request, resource node search, acquisition, heart beat and upgrade detection, etc.. The last chapter is the design scheme of the data registration center, the data registration center association mechanism, the data registration center interaction protocol.The main innovations and research results of this thesis are as follows:1. This paper proposes a connection mechanism of data registration center based on data registration center standard of DOA, and preliminary designs data registration center interactive protocol which achieves node registration, node synchronization, data resource reguest and obtain, node creation and search, data registration.2. In the study of the association mechanism of the data registration center of DOA, the requirement of DOA to the system scalability is reflected. Therefore, this paper proposes a system level / application level DOA based system architecture which can be extended, low coupling, high feasible, as well as a DOA interaction mechanism based on this architecture.3. This paper designs and achieves DOA data registry function design, interface design, code implementation, and based on a practical project, the theory put forward a feasible data registry architecture specification, data storage and exchange specification, data registration regulations, and it provides basis for further DOA study.
