“Data to Decisions” strategic initiative, believes that, without dramatic improvements, data volumes from next-generation sensors and the complexity of integrated systems will far outpace the ability of analysts to consume it.11

Meta-data management. Meta-data, which is commonly defined as “data about the data” is used to ensure traceability throughout the environment and ensure there is a common understanding of the meaning of the information contained in the BI environment.
