• advantages of using a web authoring application

  Little technical knowledge needed - developers can create professional applications with little programming knowledge.

  Update links - authoring applications will often update hyperlinks for the developer when they move content around using the correct folder management tool.
• disadvantages of web authoring application

  Limited options: often the developer will have to revert to coding if complex interactions are required in the multimedia application they are developing.
