Application modernisation is a particularly useful option for bringing legacy Uniface software up-to-date with the latest SOA (Services Oriented Architecture) applications and web services interfaces. You can even add a modern Uniface layer (using web services) to non-Uniface legacy, although this wonâ€™t be covered in detail here. The modernisation process will be easier as long as the legacy application is well structured (more likely if it is written to a defined architecture or framework) and delivering proven business benefit. In many cases, much of the existing code can be re-used, thus reducing the cost and resources needed to deliver business functionality.
The recommended approach to modernisation is to adopt a staged approach, based on modernising logically coherent subsets of business functionality, piece by piece. Reusing existing assets is efficient and tool-based review and re-mediation of these assets can ensure that application quality improves, and complexity doesnâ€™t increase out of step with business function, as modernisation proceeds. Users are delivered the very best modern â€˜look and feelâ€™ (or user experience) in stages, each stage supported by its own business case.
