Adding a web interface to your current legacy system will allow your customers to use their current green screen information anywhere internet access is available within your security scheme.
You can provide flexible access to internal users, field service/ sales or customers.
This kind of a project can be a good first step into modernization when the most important business need is to make today's information available in more locations.
Typical Legacy System UI
The typical legacy system uses a green screen terminal for user access. In the past many companies have opted for screen-scraping technology that would allow them to provide a way for other systems to interact with the mainframe. This approach works but can become very constraining since there is usually dependence on a vendor for the screen-scraping technology. TMG's approach to web-wrapping your mainframe application uses standard technologies that can be modified by your staff and won't tie you to a single vendor's technology.
Value of TMG's approach
- Simpler architecture than screen-scraping
- Post conversion vendor independence
- Compatible with future change
- Compatible with other modernizations including SOA
Comparison of Projects
| Traditional Manual Web-Enable Project | TMG Web-Enable Project |
| Inconsistent conversion of screen interfaces to web-enabled interfaces. | Rule-based automation changes all screen interfaces consistently into web interfaces. |
| Time consuming manual effort to find. | User Interface elements and add web interfaces. DMS Modernization Technology brings automation to the effort of identifying source code that relates to each desired User Interface element that needs web-enabled. |
| Screen-Scraping technology can lock you into a single vendor. | TMG Web-Enabling uses industry standard technologies that do not lock you into any single vendor. |
TMG's DMS Modernization Technology consumes the source code of your legacy application identifying the screen and data elements. Once these are identified, we will then use the same technology to add or replace your green screen functionality with web technology.
The diagram above shows how TMG's iterative approach using DMS Modernization Technology consumes your mainframe source code, processes it into a web enabled version and is tested and inspected for necessary changes. This process is completed on your entire system 5-7 times. This is an agile approach that allows for visual review of the conversion results at each iteration.
The resulting new application allows easy access for your users from any remote location. This first step of adding a web interface can jumpstart your modernization efforts and provide faster results for your users.
