Informatica PowerCenter provides the perfect platform to utilize and leverage business data. It allows you to easily, conveniently, and efficiently work on different types of data.
This book covers functionality such as creating/importing source and target, identifying errors, and debugging your mapping through a series of comprehensive tutorials. Besides learning about types of Slowly Changing Dimensions (SCDs), you will learn to create and link workflows. As you progress, exhaustive knowledge of transformations and techniques to create folders, migrate code, and optimize system performance will be explored in detail.
The step-by-step approach and adoption of real-time scenarios will guide you through effectively accessing all core functionalities offered by Informatica PowerCenter.
