Abstract: “The KISTERS AG is a German company which provides software solution such as for the energy markets, for environment protection and for management of water and air. Since, it needs to extend new functions for their Java swing-based application. Unfortunately, this legacy technology has insufficient beneficial tools compared with a RCP technology, which offers such as GUI creating framework. Consequently, KISTERS has come up with ideas of both migrating several of their existing Time series management (TSM) Client Applications, utilized for controlling, such as, hydrological and environmental systems, onto the Eclipse platform and reusing beneficial functions by merging them from existing applications. The project aims to apply a framework for requirement gathering and a prototyping approach in order for collection application requirements and incremental exploration a software development respectively. Expected outcome of the discussion is a new standalone TSM Client Application (TCA) r”
