NoSQL-based cross-engineering or cross-sheet primitive retrieval method and system

The invention provides a NoSQL-based cross-engineering or cross-sheet primitive retrieval method and system. The method comprises the steps of obtaining a NoSQL storage structure of a designed vectorgraph; using unstructured database technology to store vector graph files; the retrieval being carried out according to the input primitive retrieval words; the output retrieval result being obtained,thereby obtaining the information of the related primitive. According to the invention, graphic element retrieval, calling and managing across a map sheet or across an engineering can be performed from the basic unit-graphic element level of the vector diagram to overcome the bottleneck of abundant data and information management in a large number of map sheets. It can provide powerful support for graph management, retrieval and analysis of geology, engineering, architecture and disaster from a more subtle level, and has a wide application prospect. 本发明专利提供了种基于NoSQL的跨工程或跨图幅图元检索方法及系统，所述方法包含获取设计好的矢量图的NoSQL存储结构；采用非结构化数据库
