APPICATION RE-ENGINEERING

Legacy Transformation :

When re-engineering legacy applications, we recommend a Pilot Conversion after Inventory Analysis and Baseline before getting into the Main Conversion, in a phase-by-phase manner based on the size, complexity, inter-dependency, and criticality of these applications. Here are a few examples.

Alpha-VMS Oracle to Windows 2003 .Net:

We have re-engineered an Oracle 10g RDBMS based mission-critical system [that was using Oracle’s client-server technology of the mid 1990’s for almost one decade] for an US-based client, into .Net 2003 platform, keeping existing functionality intact and adding a few new features in the process. There were two phases (Phase-I for Conversion of online Forms 6i GUI to .Net GUI, and Phase-II for Conversion of Alpha-VMS Pro*C batch programs to Windows 2003 executables using a 3rd party tool called BJS) in this 10 person-years project that was completed in 12 months.

Our In-house ROBUST Tool:

Using our expertise on client-server and object-oriented technologies, we have developed a proprietary process framework for re-engineering legacy applications from typical client-server platforms like Oracle Forms or VB-Access or Lotus Notes platform to an object-oriented one like .Net or Java. Our framework enables you to re-engineer your legacy applications to object oriented platforms of your choice in a cost-effective manner without sacrificing your existing business rules. This framework consists of a methodology that can be tailored to meet specific needs, a set of tools and checklists. Source programs are parsed to build reverse-engineered XML based object repository, which is then used to build a default UML based object model. This object model can be used to feed standard object modeling tools like Rational Suite, or industry standard IDE’s like Microsoft VSTS for forward engineering.

Oracle Forms & Reports Upgrade:

Using our Oracle expertise, we have helped one global fashion garment retailer, having country-wide presence in the USA, to upgrade a bunch of client-server OLTP applications from their existing Oracle Forms 4.5 [there were close to 100 GUI forms and close to 50 Character-mode forms] to full-fledged Oracle 10g environment. It took us less than three months to complete the migration, including unit testing, integrated system testing, and documentation of individual forms.
