Systems and methods for multi-tiered data storage abstraction layer

A method for storing data for a building management system (BMS), the method comprising:

• providing a consistent endpoint for BMS data to an application that provides or consumes the BMS data regardless of whether the BMS data is stored in an operational data store or a cache data store;
• obtaining a requested data object of the BMS data from the cache data store in response to a determination that the requested data object is available in the cache data store;
• obtaining the requested data object from the operational data store in response to a determination that the requested data object is not available in the cache data store;
• and
• storing a redundant copy of at least a portion of the BMS data in the operational data store in the cache data store, the redundant copy of the at least a portion of the BMS data being associated with the requested data object.

A building management device for storing building management system (BMS) data, the building management device comprising one or more processors configured to:

• provide a consistent endpoint for BMS data to an application that provides or consumes the BMS data regardless of whether the BMS data is stored in a first data store, a second data store or a third data store;
• obtain a requested data object of the BMS data from the second data store in response to a determination that the requested data object is available in the second data store;
• and
• obtain the requested data object from the first data store or the third data store in response to a determination that the requested data object is not available in the second data store,
• wherein:
• the first data store is configured to store the BMS data;
• and
• the second data store is configured to store a redundant copy of at least a portion of the BMS data stored in the first data store or the third data store.
