The plan aims to detail implementation steps for building the city's "Shared Data Repository (Data Lakehouse)," a task assigned under Action Plan No. 20-KH/BCĐ57, issued by the Hanoi Party Committee's Steering Committee 57 on January 19, 2026, and Plan No. 38/KH-UBND, issued by the Hanoi People's Committee on January 26, 2026.

The initiative is intended to ensure timely, coordinated and consistent cooperation among city agencies while complying with regulations and implementation schedules. It focuses on collecting, consolidating, standardizing, connecting, and integrating data into the city's shared repository to support management, leadership, decision-making, and data utilization.

The plan identifies data as a foundational resource for governance, administration, and policymaking. It calls for a comprehensive review, standardization, and effective use of data sources to ensure information is accurate, complete, clean, consistent, interoperable, and shareable. The effort also seeks to address fragmented, disconnected, and underutilized data systems.

Authorities will review, standardize, and catalog datasets and information systems while improving sector-specific databases under their management. The goal is to ensure data is accurate, complete, clean, up-to-date, consistent, and suitable for sharing and integration into the city's shared data repository.

The city will finalize the overall architecture and technical requirements for integrating data into the repository, ensuring compatibility with Hanoi's data architecture, data-sharing platforms, and common information systems.

Technical infrastructure supporting the shared repository will be upgraded to ensure capacity for receiving, storing, processing, managing, and utilizing data from city departments and agencies in accordance with the approved roadmap.

The Shared Data Repository system will be deployed in accordance with regulations, ensuring consistency and interoperability. Technical guidance will be provided to focal points within departments and agencies regarding procedures, templates, and tools for integrating data into the platform.

Priority will be given to reviewing, standardizing, integrating, and sharing datasets that directly support city management and decision-making, administrative procedures, document appraisal, and data use in economic, social, public welfare, urban development, and technical infrastructure sectors.

Agencies responsible for data management will connect, share, and integrate their datasets into the repository according to technical requirements, implementation schedules, and guidance issued by the Department of Science and Technology. Priority will also be given to applying data in operational processes to improve digital transformation outcomes, reduce processing times, eliminate repeated requests for information already available in government systems, and support the leadership and management needs of the Hanoi People's Committee.

Data integration, migration, and standardization will be carried out under a roadmap between data-owning agencies and the Department of Science and Technology, ensuring that existing information systems continue operating without disruption.

The city will develop tools and applications to support data-driven governance and administration. Priority will be given to executive dashboards, consolidated reporting systems, shared data services, and cross-sector data applications.

A common digital dashboard system will be deployed to support city leaders, departments, agencies, and affiliated units. The system will cover areas including socio-economic management, public investment, administrative reform, public service delivery, urban planning and land management, science and technology, innovation, and digital transformation.

The city will also develop artificial intelligence applications based on data from the Shared Data Repository platform. Initial pilot projects will focus on five priority areas:

• Socio-economic data analysis to support decision-making and governance. 
  
• Analysis of citizen and organizational feedback submitted through the iHanoi application.
  
• Support for reviewing investment and construction dossiers. 
• Assistance in processing administrative procedures. 
• Development of shared datasets for training specialized AI models serving Hanoi's management and operational needs.
