Striving towards Near Real-Time Data Integration for Data Warehouses [chapter]

Robert M. Bruckner, Beate List, Josef Schiefer
2002 Lecture Notes in Computer Science  
The decision making process in traditional data warehouse environments is often delayed because data cannot be propagated from the source system to the data warehouse in time.  ...  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.  ...  Near real-time integration for data warehouses does not minimize capturing and propagation delays of the operational source systems of an organization, which are responsible for capturing real world events  ...

Process-Oriented Requirement Analysis Supporting the Data Warehouse Design Process A Use Case Driven Approach [chapter]

Beate List, Josef Schiefer, A. Min Tjoa
2000 Lecture Notes in Computer Science  
This paper explains how use cases can be used to elicit requirements for data warehouse systems, and how to involve the organisational context in the modelling process.  ...  Data warehouse systems generally concern many organisational units. Therefore, the collection of unambiguous, complete, verifiable, consistent and usable requirements can be a very difficult task.  ...  Stakeholders of a data warehouse system are interested in analysing their business processes in a comprehensive and flexible way.  ...

Near Real-Time Data Warehousing Using State-of-the-Art ETL Tools [chapter]

Thomas Jörg, Stefan Dessloch
2010 Lecture Notes in Business Information Processing  
Data warehouses are traditionally refreshed in a periodic manner, most often on a daily basis. Thus, there is some delay between a business transaction and its appearance in the data warehouse.  ...  The most recent data is trapped in the operational sources where it is unavailable for analysis.  ...  At some point in time the change to S is captured and available in S = {[carl, mz]}. However, suppose the change capture at C is delayed and both, C and C are empty up to now.  ...

Temporal and Evolving Data Warehouse Design

Sidra Faisal, Mansoor Sarwar, Khurram Shahzad, Shahzad Sarwar, Waqar Jaffry, Muhammad Murtaza Yousaf
2017 Scientific Programming  
This paper analyses the schemes that satisfy such challenging aspects faced by a data warehouse and proposes taxonomy for characterizing the existing models to temporal data management in data warehouse  ...  This has led to the development of various schemes, including evolution of data and evolution of data model and versioning of dimensional model.  ...  The temporal data in a DW enables us to perform what-if analysis. Time stamps, such as valid time (VT), transaction time (TT), and DW loading time, are used to capture timevarying states.  ...
