Systems, methods, and devices for an enterprise internet-of-things application development platform

An application development platform implemented on one or more processors and one or more storage devices, said application development platform comprising:

• a persistence component to store time-series data in a key-value store and non-time-series data in a relational database;
• a data services component to implement abstraction over a plurality of data stores comprising the key-value store and the relational database, wherein the abstraction comprises a metadata-based mapping framework over a plurality of data formats associated with the plurality of data stores;
• a plurality of configurable transformers, wherein each configurable transformer is associated with exactly one of said plurality of data formats, wherein a configurable transformer associated with a selected data format comprises at least a transformation rule for transforming between the selected data format and a standardized data format that conforms to a canonical data model comprising standardized data definitions, without requiring direct conversion between the plurality of data formats;
• a user interface to receive a request for data having said selected data format on said application development platform, wherein said configurable transformer is configured to transform said requested data to said standardized data format that conforms to said canonical data model;
• and
• an application component for processing said transformed data, wherein said application component comprises application logic, including functions, data processing, and machine learning, configured to access or process said transformed data, wherein said application logic comprises at least two applications that have incompatible programmatic interfaces, and wherein said standardized data format is agnostic to said at least two applications, thereby enabling said at least two applications to communicate directly with each other.
