Foreseeable scalability and unlimited scalability are the key criteria of the Business Intelligence platform. DB2 meets this requirement through its unique shared-nothing architecture. Scalability is applicable to both large and small databases. Scalability and price are important, but

Then, based on the actual situation, connect the detailed category object to the Star Graph to obtain the snowflake model of the enterprise data warehouse. For example, in the AdventureWorks Business Database, products have been hierarchically cla

1. Introduction Broadly speaking, a data warehouse is a type of database, which is maintained separately with the operational database of the Organization. The data warehouse system allows various application systems to be integrated to provide a solid platform for unified historical

data sources, and databases and applications. Each part cannot communicate with each other. From this perspective: the application system currently executed is an irreplaceable system built by users, especially system data. The purpose of establishing a data warehouse is to integrate and organize the

team focus on the results of the project requirements discussion rather than the process itself. Since your communication with your client is to understand what type of data is stored and how to store it efficiently, you may need to use a new approach (along with your users) to observe the data rather than directly process the data. You can try to find hidden i

data, you may need to (with your users) adopt a new method to observe the data, instead of directly processing data. You can try to find hidden information, such as digital fluctuations in a period of time. Instead of trying to find the answer to the project's needs, you need to find the answer. 4.
