One is an information production line that produces analysis reports, data queries, and online analysis and processing, data Visualization and other products, the other is the knowledge production line, which will produce: Data Mining. The customers of these products are business decision makers, so the role of business intelligence is decision support. Enterprise Data flows from the source database to the Data Warehouse through the

The last two months have been dealing with Kettle , from the beginning did not hear, to now can skillfully use, have to say the project driven, learning things is the fastest. Well, although the task of using Kettle to cope with the project is more than enough, but still want to learn a system, summed up. For example , the job is relatively small,kettle cluster mode is not involved, and so on. Speaking of Kettle, or first talk about ETL(Extract-trans

In general, the ETL implementation of incremental updates in two ways, the first: Record the maximum value of the field, if there is a continuous increase in the data source data column, record the last processed dataset, the maximum value of the column, the second is to save HashValue, quickly check all the data, After discovering the data for the move, only the modified data is updated synchronously.1, record the maximum value of the field, use Date

Brief introduction We all know that business intelligence (Business Intelligence,bi) can bring many advantages to the organization. By collating, aggregating, and analyzing data, BI can help us discern what is happening within the organization and what is going to happen. Bi lets us identify the direction in which the organization is going or should be moving forward. The process of bi typically starts with extracting, transforming, and loading data (Extract, Transform, Load,
