THE ROLE OF DATA DICTIONARY

IT leaders from enterprises around the world have realized that acquiring and implementing commercial off-the-shelf (COTS) application packages is a smarter thing to do, than the traditional approach of developing home-grown applications. This may not be the fit-for-all solution, but it makes sense from a cost, time to market and resource standpoint. Selection and acquisition of the software package is just the first step. How the software package brings value through successful implementation, is critical to the business. Internal groups as well as industry analysts will closely watch COTS package implementation in the organization.
