The metadata management of civil aviation industry is faced with a variety of data types and standards, complex relationships and business processes, highly dynamic data changes, multi-party data sharing and access control, as well as business rules and compliance requirements management and other industry-specific problems. Noah products have the ability to support different data types in metadata management, the ability to accurately describe relationships and business processes, the flexibility to adapt to rapid data changes, support multi-party sharing and access control, and manage business rules and compliance requirements. Through self-developed logic and algorithms, metadata management can provide accurate, consistent and manageable data meta-information, support data governance and meet the business needs of the civil aviation industry.

103. Data architecture

The significance of "Intelligent Civil Aviation data Governance Specification-data Architecture" is mainly reflected in the following aspects: unifying data view, ensuring data consistency and quality, supporting business requirements, ensuring data security and privacy, managing data assets and mining data value. By means of establishing data asset catalogue and defining data standards and models, data architecture promotes data unification, standardization, flow and security, and improves the accuracy, credibility and utilization value of civil aviation industry data. provide strong support for data governance and business decision-making.

For enterprises and institutions in the industry, the data asset catalog unifies data management, increases data visibility and controllability, promotes data sharing and collaboration, and supports data governance and compliance management. at the same time, it helps enterprises and institutions tap the value and potential of data, thus improving the efficiency of data utilization and the accuracy of business decision-making.

Noah products strictly comply with the civil aviation data asset catalogue requirements put forward in the standard, and follow the data hierarchical structure of "domain-business domain-business object-logical data entity-attribute". The data resource catalog specification suitable for airport, aviation department and air traffic control is formed, and based on this as the basic template, the automatic data management from industry data model, attribute label to data consanguinity tracking is realized in the product. Data resources can be automatically discovered, classified, and registered. This reduces the workload of manual operation and improves the efficiency of updating and maintaining the data resource directory.

Noah products in terms of technical architecture, the use of lake-warehouse integrated technology in the civil aviation industry data governance project also has important value. It integrates different data sources, unifies views, strengthens data analysis capabilities, integrates data, enhances data analysis capabilities, real-time data applications, data security and compliance, and reduces management costs. It helps civil aviation customers to gain more insight and value from data and provide data-driven decision support. At the same time, lake and warehouse integrated technology ensures data security and compliance, reduces data management costs, and helps civil navigation customers to achieve efficient data processing and management.

In the process of data governance service in civil aviation industry, Zhong Bing Zhihang has always regarded the improvement of data quality as one of the core tasks of data governance. In implementation, data quality objectives such as integrity, standardization, timeliness and correctness of business data need to be managed, in which the standardization of data is important, but whether the data meets the quality requirements at the business level is more important. therefore, correctness, completeness and timeliness need to develop different business check quality standards one by one according to the business scenarios of different data items. The data quality management system of Zhongbing Noah Noah data Center realizes the function of free definition of data quality checking rules and indicators, forms the standard of data quality index assessment, and successively formulates business data quality checking rules suitable for more than 1000 data items in the airport, which can quickly realize the check, governance and tracking of data quality. At the same time, it also constructs a set of index system for the improvement of data quality, understands the quality of each data source in real time through the quality check tool, forms the data quality report, and ranks the quality of each system. Each system can trace the reason of data quality according to the data quality checking tool, which is used to guide the orderly and continuous improvement of data quality.

108. Data services

Intelligent Civil Aviation data Governance data quality Specification defines industry data service criteria, data service design and operation process, data set service and data API service, data analysis capacity building and other detailed specifications, in order to build an efficient and reusable data service system in civil aviation industry and give full play to the value of data.

The data application based on the data service mode is shown in the figure above, and the specific process includes:

1. The data is aggregated into a unified data resource pool through physical aggregation or virtual aggregation, and connected by data topics to form topic data for data applications.

2. Data consumers obtain all kinds of data on demand through dataset services and data API services to support business requirements.

3. Realize the data application through the mode of the combination of data service and self-help analysis, including the realization of data application by calling data service, and the realization of data self-service analysis based on the data provided by data service and data analysis component.

Zhongbing Noah Noah data service platform is positioned as the core platform for data sharing and exchange, providing enterprises with a comprehensive data sharing and service system. The platform includes service release, service retrieval, service application, service invocation, authentication management, access control and other functions, realizes API hosting, authentication, authorization and management applications, provides rapid data table generation API interface services, and provides external calls.
