Discovering metadata process known as data profiling. Data profiling focus on examining the data sets and collecting metadata such as statistics or informative summaries about that data. In this chapter, we will discuss the importance of data profiling and shed light on the area of data profiling in big data. In addition, we will detail data profiling use cases and reviewing the state-of-the-art data profiling systems and techniques.
