Building automation system with live memory management

A non-transitory computer readable medium having machine instructions stored therein, the instructions being executable by a processor of a building management system of a building to perform operations comprising:

• receiving data for a property of a data model;
• generating serialized data for the property of the data model by serializing the received data;
• storing the serialized data in a memory device, wherein the plurality of relationships link the property of the data model to the serialized data;
• receiving a request for a property of the data model stored in the memory device, wherein the data model comprises a plurality of relationships, wherein each relationship links one of a plurality of properties to serialized building data stored within the memory device;
• and
• generating de-serialized data for the requested property in response to receiving the request by retrieving the serialized data from the memory device based on the plurality of relationships of the data model and de-serializing the retrieved serialized data.
