• [P142] A Field-Oriented Approach to Web Form Validation for Database-Isolated Rule
  Author(s): Liang Zhou
  
  

  Abstract
  We address why, and especially how, to represent Field-Oriented XML-based rule file in form validation for web applications. Motivated by the decades-old problem of frequently changing requirements for software development, we propose a descriptive solution to validation on web form data. By extracting all Database-Isolated Rules, which are to be implemented on both client-side and server-side, into standalone rule file in a Field-Oriented format, management of business rules on either side can be simplified to a great extent. The main advantage of our approach is a consistency guarantee of validation logic performed by presentation and application layer, as well as prominent clarity in representation and notable flexibility in modification. It's a tailored replacement for traditional realization of hard-code, which results in redundant work, tight coupling structure, and highly possible inconformity of rules between both sides.
