I have been involved in a DW Project (Sony China tri-one project) in Sony recently ), It is mainly responsible for ETL the user's production and analysis data from SAP to the pool built in Oracle, and provides corresponding data interfaces for other systems. In addition, this pool is designed and built based on user requirements.Objectively speaking, part of our work is the foundation and key core of this branch project in the DW project. Of course, p

Understanding requirements Like all IT projects, the best way to start an ETL project is to understand the overall requirements of the BI solution you want to build, and then decide how to use the data to best meet these requirements. In the first series of articles, the author provides the background of BI solutions. In this case, the object is Adventure Works, a virtual company that needs BI solutions. This article lists the analysis requirements by

What is Data extractionData extraction refers to the data that is needed to extract the destination data source system from the source data source system. In practical application, the data source is mostly used in relational database.EditHow data is pumped(a) Full-scale extractionFull-volume extraction is similar to data migration or data replication, which extracts the data from a table or view in the data source intact from the database and transforms it into a format that your

Sometimes you will find that the locked resource is not released for a long time, even if the session state is "killed", it will still block other sessions. Below, based on Eygel's "Kill session

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,
