Refactoring Services

Overview

Refactoring is a form of systems maintenance which "cleans up" the system by removing unused codes and by consolidating duplicated codes. The result is an optimized system which offers improved productivity and further easing future maintenance requirements.

Refactoring is often included as part of the Modernization Service (Legacy Migration Service) whereby unused and duplicated codes resulting from tool migration is cleaned up and consolidated. The source codes are further tuned and extension tools are added, making the system perform optimally.

Right after tool migration, the resulting set of codes often includes duplicated or dead codes. The codes are then run through a refactoring process to remove the dead codes and to consolidate the duplicated codes. The objective is to optimize the system in order to maximize the potential of the new platform.

Often, a set of legacy system codes increases in terms of number of steps/lines of code after it has gone through straight conversion. Although the resulting code is in working order, it is not optimized.

Tool migration makes it possible to finish migration in short time and at low cost. However, converted codes are not easy to understand from a viewpoint of a Java programmer. Refactoring will make the codes look more familiar to the Java programmers.

Compared to after straight conversion, the processing speed of the refactored codes is two times faster. Faster processing speed can translate to higher end-user productivity.

After refactoring, the source codes become more familiar from the viewpoint of Java engineer. This makes it easier for the Java engineers to maintain and enhance the system, allowing business process improvements and innovations.
