JSON persistence service

A system for transferring data between a client and a relational system comprising a relational model defined by tables, the system comprising:

• one or more non-transitory computer-readable storage media storing:
• an object model, wherein the object model is at least partially defined by a JSON object class;
• and
• an object relational mapping (ORM) data structure defining a mapping between the object model and the relational model, the ORM data structure produced from a declarative ORM specification;
• and
• one or more hardware processors executing a data object persistence service, wherein the data object persistence service comprises an object request processing service and a JavaScript language ORM service comprising a JavaScript language ORM API processing service and a Java ORM system, and wherein executing the data object persistence service comprises:
• receiving a REST API call to transfer data of a JSON object of the JSON object class between the client and the relational system;
• and
• transferring the data of the JSON object between the client and the relational system according to the mapping between the object model and the relational model defined by the ORM data structure in response to receiving the REST API call, wherein transferring the data comprises:
• translating the REST API call to a JavaScript language ORM API call with the object request processing service;
• performing data transfer by the JavaScript language ORM service in response to the JavaScript language ORM API call;
• translating the JavaScript language ORM API call to a Java language ORM API call with the JavaScript language ORM API processing service;
• and
• performing, by the Java ORM system using a database interface service operable to store and receive data in the relational system, data transfer between the JavaScript language ORM API processing service and the relational system according to the declarative ORM specification in response to the translated Java language ORM API call from the JavaScript language ORM API processing service.

A computer program product for converting object-oriented data object requests into database operations to be performed on data in a database, the computer program product comprising:

• one or more non-transitory computer-readable storage media comprising instructions, which when executed by one or more processors, cause:
• receiving, at an object request processing service, REST API requests;
• translating, by the object request processing service, input parameters of a REST API request into corresponding JavaScript parameters and a JavaScript request;
• translating, by a JavaScript language object relational mapping (ORM) service that is communicatively coupled to the object request processing service, the JavaScript request into a corresponding Java request by using a JavaScript-to-Java bridging service;
• and
• translating, by a Java ORM system that is communicatively coupled to the JavaScript language ORM service and an ORM data structure, the Java request into one or more database operations by mapping Java request operations and Java request parameters from the Java request to corresponding database properties defined in the ORM data structure, the ORM data structure defining a mapping between data object attributes of an object model and database properties defined within a database schema of the database, wherein the object model is at least partially defined by a JSON object class;
• and
• a communication layer, communicatively coupled to one or more external client devices, the database, the object request processing service, and the Java ORM system, and operable to send and receive data communications between internal elements of the computer program product and computing elements external to the computer program product.
