Unstructured Data Registration Specification And Registration Prototype Study Under DOA

Now,high rapid informationization,the scale of Internet data has grown exponentially,and complex businesses in various fields have been formed.This has further caused the heterogeneity and complexity of data.Structure of data can be divided into structured and semi-structured.Unstructured,in which unstructured data has great potential value,there are characteristics of owner(ownership)for controlled unstructured data.The national government uses data and analyses to better manage the country's social and economic security.Companies use data to analyze user behavior,enhance user experience,and provide data interface services to share data.Personal users use client and browser-side programs to generate a large amount of personal data.Many of the data are very valuable.Sharing data can bring more benefits.Cloud computing,artificial intelligence,mobile Internet and other technologies all require the support of data operations.They are essentially data processing and control management.Complex and diverse data environments also promote the production of new technologies such as Handle and blockchain.These Internet technologies have brought a lot of convenience and enlightenment to data management applications.Everything is about data.This paper studies data management and application from the data-oriented architecture(DOA,Data Oriented Architecture)related articles.DOA is a data-oriented and data-centric solution that addresses data,security,and application issues and builds a data services platform.From the perspective of the development of human society and Internet technology,the influence of data and information is very large.The sharing of data resources is an important factor that causes change.Due to the limitations of traditional Internet development,various system platforms are blocked and information islands are formed,resulting in data not being able to effectively share applications,especially unstructured data of a complex type.The registration of unstructured data under DOA is data-centric,referring to Dublin metadata as a reference,analyzing attribute information of general data applications,and combining the principles of registration data in DOA's ideological system architecture,summarizing the registration specifications for unstructured data.These specifications link unstructured data with people,use RESTful API technology to manage data resources with agility,and provide external interfaces to facilitate users to manage unstructured data and build data sharing platforms.The research content of this paper:(1)Study and analyze the theoretical results of the latest data management and processing technologies.Aiming at the current technology Handle,blockchain,and data-oriented architecture,we compare the technology background,technical content description,and application fields.(2)Study and learn the principles of DOA technology architecture.Under the overall framework of cognitive DOA,considering the application of data management,the data register center(DRC)model structure in DOA is described in depth.(3)Study the specification of unstructured data registration.Describe the characteristics of unstructured data,and develop a registration scheme for unstructured data in the data registry for the characteristics of Dublin metadata.(4)Data register center prototype development design.Based on the characteristics of DRC,we design and prototype the unstructured data registration system.Combine RESTful APIs to develop system prototypes and simulate environmental tests.The main research results of this paper are as follows:(1)Completion of DRC research on unstructured data specificationComparing with Handle and blockchain technology,researching and analyzing the data-oriented architecture scheme,and deep understanding of the DRC registration structure to complete the specification description of unstructured data registration information,including unstructured data registration information and the owner Associated description.(2)Complete the RESTful API Data Interface Application for Registered PrototypesCompleted the unstructured data registry center prototype design,based on Django Web as the basis of the platform,RESTful API development,external interface to provide unstructured data registration,access and management.The initial implementation of the prototype was completed and tested successfully.
