DOA is Data Oriented Architecture.

DOA is built on top of the hardware architecture of cloud computing, adopting the idea of "data-oriented and data-centric" through the Data Register Center (DRC, Data Register Center), Data Authority Center (DAC, DataException Control Center), and Data Exception Center (DEC, DataException Control Center). Authority Center (DAC, Data Authority Center), and DataException Control Center (DEC, DataException Control Center) to unify the definition of data, data management and data services.

Through DAUs (Data Application Units) to manage and serve various applications, establish a data ecosystem with a large data platform and fragmented applications, and build up a whole set of mechanisms from data protection to authorized applications, which provide basic theories and methodologies and technologies for effectively solving the problems of software architecture in the era of big data.

Specifically

Introduction

Data Registry Center (DRC) is the core component of DOA, through which a logical pool of data resources is constructed, and data is managed and data services are provided; DRC is designed in accordance with a unified standard, and DRCs from various industries or of different scales can be interconnected and associated, so as to make up a larger-scale DOA system.

The Data Authority Center (DAC), a key component of DOA, manages the secure storage, transmission and application authorization of data. It implements the mechanism of "Born Encrypted, Authorized to Use" for the data, dividing the data into the "data state" which is encrypted when stored and transmitted, and the "application state" which is decrypted when authorized to use in the application. The data is divided into a "data state" that is encrypted during storage and transmission, and an "application state" that is decrypted during authorized use in the application.
