After 45 years working as business data processing specialist I reached the retirement age. Nevertheless I would still like to assist you
with finding solutions concerning your information technology requirements.
In addition to my experience with different programming languages my core competence is the modernization of existing COBOL programs to run on the .NET platform.
Micro Focus Visual COBOL as an integrated .NET language within Microsoft Visual Studio is an ideal platform for developing business applications.
Visual COBOL offers many new features, like OpenESQL and ADO for processing databases and datasets, simple commands for creating collections,
several possibilities for defining properties and parameters. This makes it easy to develop an application using different programming languages
including calling functions of the .NET framework.
My favourite system architecture is the use of web services to handle the business logic including database access.
The web services can be called from different client types, like WPF, Winform, web applications and B2B interfaces.
Using XML documents enables the exchange of very complex data structures.
This architecture results in a strict separation between business logic and user interface and is therefore very flexible.
Preferably, I code the user interface as WPF programs written in C#. Of course WPF programs can also be coded in COBOL.
It is important to save the big value of proven COBOL programs. In combination with all the new facilities this is safer, more efficient
and, therefore, also more economic than reprogramming.
