One of the core objectives of Digital Transformation is to substantially improve the productivity across the business. Productivity is measured in terms of financial performance, increased speed and throughput in all parts of their businesses, and reduction in NVA (non-value-added) time, and efforts. To achieve productivity goals, there is a clear need to rapidly implement intuitive end-user centric \'For-purpose\' Applications and provide on-demand \'visibility\' across business processes with A/BI capabilities. These apps need to access contextual data from multiple systems to enable end users carry out their end-to-end business transactions. Security and access control of underlying source systems must be honored.
