This document discusses data management and the challenges organizations face. It explains that data becomes valuable information and knowledge when analyzed. There are two main formats that store data - structured and unstructured. The objective of data management is to transform raw data into high quality corporate information by comprehending, integrating, and improving data quality over time. Managing large volumes of diverse data from multiple sources in different formats has become complex. Effective data governance, including formal processes and practices, is needed to ensure data is handled properly and the most valuable organizational asset - information - can be used efficiently.
