Yesterday, they were the only options available. You don't have to redesign your back-end systems in order to make it easy for customers to access them. Today, a new application mining technology moves beyond these methods to deliver the first practical solution for extending legacy information to partners and consumers via the web. Application mining technology makes it possible to extract data and logic from mainframe applications and then reuse them to build e-business solutions. Two types of solutions are available.
Invasive products require developers to alter the legacy source code.
Non-invasive products do not. Unlike other application mining products, the WRQ solution allows developers to view mainframe applications as either objects or databases. That means they can use JDBC, or JavaBeans and COM objects, to easily integrate mainframe information from multiple applications and hosts into customer-driven web applications. The back-end legacy logic is left untouched. WRQ's application mining technology allows developers to model the legacy application and view extracted information as either objects or databases.
