A typical corporation depends on a large number of legacy applications to carry on its day-to-day business. As new technology emerges, businesses need to contend with the challenges of updating a variety of software across multiple environments, devices and locations.
Businesses that are part of the digital economy may find it particularly relevant to extend the use of their legacy applications to continue to meet the needs of their customers without disruptions.
Online and mobile commerce puts a heavy burden on legacy IT systems with large requests for products and other relevant data.
Extending legacy applications for improved efficiency
Companies that depend on legacy systems are required to integrate newer digital technologies with their existing legacy technology to maximize their IT investments. Most of the time, legacy applications are viable and may only need enhancements.
In the case of older applications that run on the IBM System z or IBM System i platforms, users may still be accessing critical business applications through traditional, text-based interfaces.
Traditional 3270 and 5250 green screens may not be user-friendly today but despite these disadvantages, these terminal applications are proven, stable and represent a tremendous business investment and value. This can make them costly to replace and making changes to these come with risks.
To optimally use their technology, businesses need to carefully consider the latest modernization approaches. Application modernization services can help IT teams cut costs and free staff to focus on other opportunities.
IBM Rational Host Access Transformation Services (HATS)
Businesses can use IBM Rational Host Access Transformation Services (HATS) to reuse and transform their existing legacy applications with improved user interfaces. HATS can help extend their use and integrate them with other applications with minimal risk.
Solutions based on HATS can make it quicker and simpler to replace outdated terminal displays and easily transform old 3270 and 5250 green screen applications to web, portlet, rich client or mobile device user interfaces. HATS can also extend 3270, 5250 and VT green screens as standard web services.
Key benefits of the HATS solution
An important benefit is the ease of use that HATS offers. It allows quick and easy modification of the workflow and navigation of host applications without the need to modify the source code.
The HATS toolkit is easy to use and does not require programming for most customization tasks, which reduces the manual effort and helps developers be more productive.
The HATS solution also allows extensive customization for applications meant for a specific set of end users. It can remove irrelevant information, organize data efficiently and display only those fields that are required.
With HATS, developers can easily reorganize and modify text, create navigation buttons to reduce data entry errors and enhance productivity. When a HATS application is deployed in the production environment, end users can interact with it via a transformed and streamlined user interface.
IBM HATS adds value while cutting costs, reducing disruptions and minimizing risk and allows legacy applications to perform more efficiently for improved performance.
