Object mapping and conversion system

A system for converting data between an input object model and an output object model, the system comprising:

• an input JSON object class at least partially defining the input object model and an output JSON object class at least partially defining the output object model;
• an object container stored in a non-transitory machine-readable medium and encapsulating a first JSON object of the input JSON object class;
• an object conversion system (OCS) data structure stored in a non-transitory machine-readable medium and defining a mapping between the input object model and the output object model, the OCS data structure produced from a declarative OCS specification based on an OCS grammar, the declarative OCS specification selects at least one of the attributes of the input JSON object class for converting data from the input object model to the output object model;
• and
• an exchange unit for converting data of the first JSON object, through the object container, from the input object model to the output object model.

A system for converting data between an input object model and an output object model, wherein the input object model is at least partially defined by at least two linked object classes, and at least one output object class defining an output object model, the system comprising:

• an OCS data structure stored in a non-transitory machine-readable medium and defining a mapping between the input object model and the output object model, the OCS data structure produced from a declarative OCS specification based on an OCS grammar, the declarative OCS specification comprising a path expression for mapping a nested attribute of the at least two linked object classes;
• an object container stored in a non-transitory machine-readable medium and encapsulating a first instance of objects of the at least two linked object classes;
• and
• an exchange unit operable to convert data of the first instance of objects of the at least two linked object classes from the input object model, through the object container, to data of an output object of the output object model wherein the value of the nested attribute of the first instance of objects of the at least two linked object classes is used to set the value of a top-level attribute of the output object.

A system for converting data between an object-oriented system comprising an input object model and an output object model, and a relational system comprising a relational model defined by tables, the system comprising:

• at least one input object class at least partially defining the input object model and at least one output object class at least partially defining the output object model;
• a first object container stored in a non-transitory machine-readable medium and encapsulating an input object of a class in the input object model;
• an object conversion system (OCS) data structure stored in a non-transitory machine-readable medium and defining a mapping between the input object model and the output object model, the OCS data structure produced from a declarative OCS specification based on an OCS grammar, the declarative OCS specification selects at least one of the attributes of the class in the input object model for converting data from the input object model to the output object model;
• a first exchange unit for converting data of the input object, through the first object container, to data of an output object of the output object model;
• a second object container stored in a non-transitory machine-readable medium and encapsulating a second object, wherein the second object is either the input object or the output object;
• an object relational mapping (ORM) data structure stored in a non-transitory machine-readable medium and defining a mapping between at least one of the input object model and the output object model to the relational model, the ORM data structure generated produced from a declarative ORM specification based on an ORM grammar;
• and
• a second exchange unit operable to convert data from at least one of the input object model and the output object model to the relational model through the second object container encapsulating the second object.
