LEGACY MODERNIZATION - QAT Genesis

Solution Mapping – Mapping Application Processing Elements

QAT Genesis provides software automation for several of the critical functional elements of a given legacy application. This service provided by QAT will map functional elements of each legacy application to the solutions provided by QAT Genesis.

Modernization Paths by QAT Genesis

Current Situation	Business Need	QAT Genesis Modernization  Solution	Results

Limited qualified and available resources to work on legacy systems	Changes in business rules require adding, modifying, and sustaining functionality more easily	Agility BPM™ Business Process Automation	Simplified new development and maintenance enables organizations to respond quickly and cost effectively to changing business conditions
Systems are insufficiently documented; unclear plan for sustaining operations	Inventory legacy system applications and databases; identify interdependencies and plan modernization actions in legacy environments	QAT Assessment Services Legacy Portfolio Assessment	Provides technology leaders with a framework to evaluate alternatives for legacy systems modernization

Once the modernization path is established, it is important to understand the various solutions available and map those to the solution. Any or all of these solutions could be mapped to various functional elements of the application.

Navigation and Integration – QAT WebDaptive is the development/runtime framework used for QAT Genesis. This automates the home page and the navigation of the application using any combination of top level menus, left-hand tree and tabs. This is also what enables the seamless integration of all the technologies described here as well as the custom CA Gen and other hand written pages.

Business Process – Agility BPM™ is a core part of the solution and will automate the business processes within the application. The CA Gen action blocks from the legacy application will be registered and re-used by Agility BPM™. However, the data collection steps and the decisions used to control the sequence and navigation of those steps will be automated by Agility BPM™ and these can be defined and managed by an analyst that understands the needs of the business. Developers are appropriately focused on thedelivery of database and integration services instead of being consumed with every detail of the business process.

Table Maintenance – QAT DDM can be used to automate the table maintenance where the business simply requires an interface to maintain the data and that maintenance doesn't include complex business rules. Many application tables can be mapped to QAT DDM saving the need to write custom interfaces for those tables.

New Gen Pages – Some traditional CA Gen application pages may still be required to support browsers and other unique functionality. In these cases, when CA Gen is the preferred development tool, QAT Wizard is used to generate the procedure (client, server and action blocks) and consume existing business rules from the CA Gen application. This rapidly produces a clean and consistent transactions that fit shop standards and are easy to maintain.

Information Publishing – Reports and forms are part of nearly all business applications. QAT Publisher generates reports and documents from the CA Gen application. Since it can be used to publish information in many different file types, it can be used to replace reports, forms, letter generation, and even documents to be shared across business areas and between businesses.

Application Security – QAT Security is an application security component that controls the authorization of functionality within the business application. It is used to replace the sometimes hard coded or home grown security that exists within many legacy applications. Powerful security rules automate what it generally coded within the applications.
