How to set up the Mappers (Structure)?

The syntax and semantics applied in data transformation is defined in a modeling context and easy to interpret, using a format or protocol (JSON - JavaScript Object Notation) of data representation, based on the JavaScript programming language, which allows defining a standardized transformation structure.

 Thus, the syntax applied in the data transformation process obeys the rules and principles defined in the JSON language format, namely: data types, properties, objects, arrays, etc..

 In semantic terms, we adopted a structure that can be reused in any plugin, in order to satisfy the exchange of data between different systems. This semantic structuring is based on the following conceptual model:

  1. Table: identification (name) of the object or array in the JSON structure of the target system;
  2. Fields: definition of the structure of an object or array (for example, the composition of the attributes of a given entity);
  3. Field: identification (name) of the property to which the transformed value will be assigned (for example, the name of an attribute of a particular entity);
  4.  Handlers: specification (properties) to be applied in data mapping and transformation (assignment of the transformed value as a function of the mapping applied).
