remove_foreign_key

Remove a foreign key between two tables

The aim of this package is to manipulate relational
data models in R.
It provides functions to create, modify and export data models
in json format.
It also allows importing models created
with 'MySQL Workbench' (<https://www.mysql.com/products/workbench/>).
These functions are accessible through a graphical user
interface made with 'shiny'.
Constraints such as types, keys, uniqueness and mandatory fields are
automatically checked and corrected when editing a model.
Finally, real data can be confronted to a model to check their compatibility.
