Deliverable 3

Title : Application to create Model

Description :

The goal is to learn jQuery and develop an application using it. In this deliverable, I developed an application for creating model components.

The application provides following functionalities :

  • Create a new table.
  • Add new fields to the table.
  • Delete table.
  • Rename table.
  • Create relationships between the tables.
