advantages of data warehouse ppt

With the advent of data warehousing equipment (Warehouse appliance), the potential of business intelligence and advanced analytics applications has been stimulated, and many enterprises will use the advantages of data warehousing technology to enhance their competitiveness. But not to say that integration equipment is

, rather than the daily transaction data processed by many databases (some databases, such as the telecom billing database and even real-time information processing ). Therefore, the data in the data warehouse is rarely or never modified. Of course, adding data to the

data redundancy caused by the problem is not the reason to apply the database paradigm. Therefore, not the higher the application paradigm, the better, depends on the actual situation. The third paradigm has largely reduced data redundancy and reduced the number of insertions, updates, and deletions. My personal view is that most of the cases applied to the third paradigm are sufficient, and in some cases

following order: First, compare the classic and common data Warehouse model, and analyze its advantages and disadvantages. The basic concepts and related theories of dimension modeling are introduced in detail. To get a better understanding of what dimension modeling is, I'm going to simulate an electric arcade that we all know well, and use the theory we've tal

mode is widely used in many preprocessing operations on each dimension, such as pre-statistics, classification, and sorting by dimension. Through these preprocessing, the Data Warehouse processing capability can be greatly improved. EspeciallyFor the 3nf modeling method, star mode has obvious performance advantages. At the same time, another advantage of the dim

control, the first is to use the analytical application of operation and production; Due to the difficulty of historical data collection, the speed of the implementation of the data warehouse is relatively slow in the government supervision Department. The Data Warehouse wi
