Three-dimensional objects are in various forms, and opinions differ as to the spatial relationships between objects. Based on a rule-based library, the authors design a new three-dimensional data model aimed at retaining the advantages and overcoming the disadvantages of the traditional models. The new model takes into account the topology of three-dimensional vector-oriented data model entities, introducing the concept of rules, unifying the relational and object data model. The success of applications shows that the model is featured by unities of expression, with a custom, scalable spatial object-relational skills between the space object and the object of its structure, adapting to the complex application requirements, and it has good application prospects.
