Smart entity management for building management systems

Abstract

One or more non-transitory computer readable media contain program instructions that, when executed by one or more processors, cause the one or more processors to perform operations including: generating a database of interconnected smart entities including object entities representing each of a plurality of objects associated with one or more buildings and the plurality of objects each representing a space, person, building subsystem, and/or device, and data entities representing data generated by the objects, the smart entities being interconnected by relational objects indicating relationships between the object entities and the data entities; receiving data from a first object of the plurality of objects; determining a second object from a relational object for the first object based on the received data; and modifying a data entity connected to an object entity of the second object within the database of smart entities based on the received data for the first object.
