But like most things technological, they do not stay the same after a year. Something new comes out that might completely change the format and render everything else useless. For that reason modernization is difficult because technology is constantly changing.

 

One of the options in improving Oracle is to completely change its implementation. But redeveloping the architecture in Oracle is even more difficult as it will require changing the entire system and even changing the applications. That will take time and resources that it could be too costly for the company if they are not properly implemented.

 

This book will try to explain how to improve Oracle with the help of SOA (Service Oriented Architecture). It is a technique that will not only require knowledge of Oracle but keen understanding on the process of SOA. This project could even be very challenging that one developer leading the team cannot handle it. It is a book that will detail the challenges as well as solutions to ease the modernization.
