详细说明： W.H. INMON DANIEL LINSTEDT Corporate data – the vista of information across the entire corporation. There are many different types of data found in the corporation. The book lays out one perspective of data and describes – at a very high level – how that data is used (and is not used) in the decision-making process of the corporation. Big Data – what is it and how can it enhance decision making in the corporation. There are different definitions of Big Data. This book takes a very pragmatic view of Big Data then discusses some salient characteristics of it. The most salient characteristic – one not discussed by the vendors – is that of the difference of repetitive and non-repetitive Big Data.

The ultimate in the evolution of data warehousing was the discipline and structure known as the “data vault.” There were and are many reasons to have the data vault as the backbone of the systems that require integrity. Operational systems – the need to run the corporation’s dayto- day business. For all the needs of managing very large data volumes and for data integrity requirements, there is (and will continue to be) a need to have systems that run and enhance the day-to-day operations of the organization. Architecture – how the different types of data and the different needs for data are fitted together, in a holistic and a cohesive way. It is one thing to recognize the different needs of perspectives of data in the corporation. It is another thing to envision how the different types of data fit together in a cohesive, holistic manner. ...展开详情收缩
