JSON (JavaScript Object notation) is a lightweight data interchange format that uses a completely language-independent text format and is an ideal data interchange format. Also, JSON is the native format of JavaScript, which means that processing JSON data in JavaScript does not require any special APIs or toolkits.

Object-Relational Mapping (O/R mapping) is a common requirement for many software development projects. The activities involved in the data persistence process are tedious and error-prone. If we take into account the inevitable changes in demand, we are faced with a lot of trouble: the data storage structure must be kept in sync with the source cod
