Description

Technical Field

[0001] The invention discloses a graph database construction method for full life cycle management of construction land, belonging to the technical field of GIS data storage and retrieval. Background Art

[0002] In today's society, with the acceleration of urbanization and the increasing shortage of land resources, the full life cycle management of construction land has become an important issue in urban planning and management. Traditional land management methods often focus on the recording of static data and simple document management, lacking effective tracking and analysis of the dynamic changes in land and their correlations. However, in modern urban construction, the planning, land allocation, land storage, land supply and registration of construction land are closely linked throughout the life cycle, and each stage involves complex administrative procedures, laws and regulations, and market dynamics.

[0003] At the same time, with the rapid development of geographic information system (GIS) technology, GIS data storage and retrieval capabilities have been significantly improved, providing new technical means for the full life cycle management of construction land. As an emerging data model, graph databases provide strong support for the storage, query and analysis of complex data with their flexible data structure and powerful relationship network analysis capabilities. Using graph databases, construction land entities and their complex relationships can be intuitively represented, providing land managers with a more intuitive, comprehensive and real-time data view.

[0004] However, there is a lack of graph database construction methods specifically for the full life cycle management of construction land on the market. Most existing solutions still remain on the traditional database architecture, which is difficult to adapt to the dynamic characteristics and complex relationships of construction land data. Therefore, developing a graph database construction method that can fully cover the full life cycle management needs of construction land is of great significance for improving the level of urban land management, optimizing land resource allocation, and improving government decision-making efficiency.

[0005] In this context, the present invention proposes a method for constructing a graph database for the full life cycle management of construction land, aiming to achieve comprehensive, real-time and efficient management of the full life cycle data of construction land through the flexible modeling capabilities and complex relationship network analysis capabilities of the graph database, and provide strong support for urban planning and management. In order to solve the above problems, the applicant proposes a method for constructing a graph database for the full life cycle management of construction land. Summary of the invention

[0010] By utilizing the modeling capabilities of the graph database, the nodes and their relationships are mapped into a graph structure to achieve full life cycle management of construction land, including data storage, retrieval, analysis and display.
