User Interface Layer
  • It is a top most layer in enterprise applications, it will improve Look and Feel to the enterprise applications.

  • It will provide very good environment to get data from users in order to execute enterprise applications.
  • It will provide very good environment to perform client side data validations by executing Java script functions.
