Application Reverse Engineering

Introduction

With the passing time, enterprises are increasingly facing the challenge of aging and old software applications, better known in computing parlance as legacy applications which are essential for the organizations but at the same time prove to be a nightmare for programmers and maintenance engineers. Though burdensome, legacy applications also represent years of accumulated experience and knowledge. It is, therefore, unwise to discard them before building new state of the art applications to leverage current technologies. There is a need to transform such legacy applications, suitable to the latest technology environment by various methods. For maximizing value, application reengineering is being increasingly embraced by organizations.

An IT Solution has been working on legacy applications since the time of Y2K problems that had turned the world in a spin when the millennium was ending and with which was ending the hope and fate of thousands of applications worldwide for their inability to recognize new date. Since then, we have developed special skills in reengineering through our own proven methods and experience. Our extensive experience and R&D strengths provide tool-based processes to achieve relatively painless reengineering of applications and help organizations reach their objectives efficiently and effectively

Offering

An IT Solution can rapidly and effectively reengineer your legacy software applications to contemporary platforms with optimized architectures, simultaneously retaining or enhancing the value of those applications. We bring together our proven processes, technology expertise and tools to reengineer your software applications to modern technologies such as .NET and J2EE.

Our global Development centers have software programming teams with proven expertise in modifying or extracting business logic from legacy systems. An IT Solution's mature programming processes, proprietary methodologies, flexible global delivery model, and stringent quality management systems minimize project Development cost; reduce time-to-market and ensure highest quality for our clients. Our best practices in application reengineering along with proprietary tools deliver optimized and cost-effective projects as solutions.

Some of the benefits that enterprises can reap from our experience are as follows: Our offerings for reengineering are as follows:
Assessment
We assess existing legacy systems to formulate a reengineering roadmap which aligns the selection of the proposed IT solution to the organization's business vision and needs and also maximizes ROI realization. Assessment includes recommending or deciding on the appropriate business and technical target architecture, evaluating build or buy opportunities, and choosing between one time and incremental system reengineering.
Language Upgradation
We leverage upon tool-based automated conversions for reengineering legacy languages into modern technologies to accommodate changing business needs.
User Interface Conversion
An IT Solution can reengineer user interfaces for enhancing ease of use, from look & feel enhancements to rewriting & redesigning interfaces among different technologies.
Database Changes
We use proprietary tools and processes for reengineering databases which produces an improved version of a legacy database according to definite criteria (correctness, freeing from obsolete constructs, normalization, optimization, distribution, using modern technologies, etc.). We use utilities which apply the prescribed design changes to snapshots of production databases so that the new data-model/database is quickly and easily constructed for on-site testing and implementation.
Technology Upgradation
Technology upgrade presents an ideal opportunity for analyzing and improving processes in an organization. An IT Solution's technology upgradation methodology examines key business process areas to identify high ROI changes. The approach also ensures minimum customization by exploiting existing processes that have been implemented in applications.

Our reengineering methodology uses a unique process of mock changes to simulate processes, views, and screens in order to test run the validity and necessity of the reengineering. This ensures clear metrics for reengineering justification and also ensures testing of applications before actual reengineering and global rollout.
