Design method and system of distributed multi-modal database system

The invention relates to the technical field of BIM (Building Information Modeling), in particular to a design method and system of a distributed multi-modal database system. Comprising the following steps: uploading a BIM model file and necessary description information of the file to a server; the server side stores the BIM model file and the necessary description information of the file into a MinIO database, and data analysis is carried out through BIM analysis software; data analysis results are stored in a distributed multi-modal database through data classification; and storing the data in the data analysis result into different databases. According to the method, the BIM model is decomposed into different data formats to be stored, a BIM model file comprises multiple types of data such as geometric information, attribute information and relation information, and the data formats are different. According to the method, the BIM files are classified and stored according to functions aiming at the problem
