Data management is the development and execution of architectures, policies, practices, and procedures in order to manage the information lifecycle needs of an enterprise in an effective manner. The effective management of corporate data has grown in importance as businesses are subject to an increasing number of compliance regulations. Furthermore, the sheer volume of data that must be managed by organizations has increased so markedly that it is sometimes referred to as big data.
Big data management is the organization, administration, and governance of large volumes of both structured and unstructured data. The goal of big data management is to ensure a high level of data quality and accessibility for business intelligence and big data analytics applications. Corporations, government agencies, and other organizations employ big data management strategies to help them contend with fast-growing pools of data, typically involving many terabytes or even peta bytes of information saved in a variety of file formats. Effective big data management helps companies locate valuable information in large sets of unstructured data and semi-structured data from a variety of sources, including call detail records, system logs and social media sites.
