Striving towards Near Real-Time Data Integration for Data Warehouses
[chapter]
2002
Lecture Notes in Computer Science
Preserved Fulltext
In this paper we present an architecture of an ETL environment for real-time data warehouses, which supports a continual near real-time data propagation. ...
The architecture takes full advantage of existing J2EE (Java 2 Platform, Enterprise Edition) technology and enables the implementation of a distributed, scalable, near real-time ETL environment. ...
Data in an ODS is subject to change every time one of its underlying details changes. ...
