Delphi Software Re-engineering

We re-engineer all types of software built with any version of Delphi

What Software Re-engineering is not

A typical re-engineering project encompasses a combination of other processes such as migration, feature enhancement, UX/UI modernization
Re-engineering is a way to build (design and develop) a new software based on the existing one, using modern technologies, approaches and hardware
Re-engineering is not migration
Re-engineering is not modernization
Re-engineering is not functionality enhancement

Reasons to reengineer software

Obsolescence of the technologies the software is built with
  • Harder and harder to find developers know those technologies
  • More and more time-money is required to add new functionality
  • User interface (UI) can not be modified or updated
The necessity to perform software migration
  • Move from Desktop to Cloud
  • Migrate to another programming language
  • Data or Business logic migration
Dissatisfaction with software maintainability
  • Poor performance and stability
  • Obsolete UI/UX
  • Integrations inability
Introduction of changes in business
  • Business-processes re-engineering
  • Business intelligence implementation
  • Artificial intelligence integration

Risks of re-engineering

Re-engineering is aimed to reduce actual and potential risks related to the usage of legacy software, but has its own risks being a complicated engineering process

Extremely high volume of manual work with another’s code
Subject matter experts of the business
Lack of management commitment
New UX is not intuitive
Update or auto update process is complex
User Interface (UI) is outdated
Expensive backups
Inappropriate re-documentation
Various test coverage issues
Missing Requirements
Inappropriate Constraints

Types of software re-engineering projects


Virtualization is a fairly old technology but it is still a super relevant approach to a system undergoing evolution in a form of re-engineering. There are several types of virtualization. Hardware virtualization. We apply a hardware virtualization approach when you switch from using legacy hardware. The existing software system is not modified. You do not pay for software modernization but the burden of legacy system maintenance costs remains. Software virtualization. There are several types of software virtualization but all of them aim to increase the utilization of computing resources.

Wrapping old code

Code wrapping is a way to get access to the existing functionality via API. Code wrapping can be an effective way for complicated legacy systems, or poorly designed software that does not support some data formats, or in other cases when we need to ensure technologies interoperability. In this type of re-engineering projects you pay for the development of code wrapping your existing system or minimal changes of the system’s source code.

Source code translation

The reasons to the source code translation are: IT infrastructure hardware update, lack of personnel capable of maintaining legacy code, regulation policy changes, loss of support for the technology the system is built with. Despite automated source code translation can be economically effective, the generated code is usually unmaintainable and does not use the paradigms of the target language. In source code translation projects you pay for code translation software software and further manual corrections to the generated code.

Data re-engineering

Your business may need data re-engineering because your system stores data in legacy databases or uses legacy DMS but not only. The other reasons may be data degradation, system built-in constraints, redundant and duplicated information collected and other reasons. Data re-engineering projects are associated with the data structures analysis and their further conversion according the the requirements of new system.

Reverse engineering

We resort to reverse engineering in a few cases. The first one is because the documentation describing how the system works has been either lost or it was never written. And the only way to incorporate the system functionality is to reverse-engineer it and then re-design it with new technology. In this case Reverse engineering is one of the steps of a re-engineering project. The second reason to reverse engineering is to build a system the source code of which you do not have access to (to repeat someone else’s success).
