Overview Work Package 3:
Building and implementation of the S-DWH: Architectural and technical aspects


In general, an architecture framework provides principles and practices for creating and using the architectural description of a S-DWH. It structures architects' thinking by dividing the architectural description into domains or views, and offers models for documenting each view. We used these models to create the deliverables of Work Packaeg 3, which will therefore describethe three domains:

  • Business

  • Information Systems

  • Technology.



The deliverables produced by the WP3 are:

3.1 “Business Architecture of the S-DWH”;


3.2 “Modular Workflow of the S-DWH”
3.3 “Functional Architecture of the S-DWH”
3.4 “Overview of various technical aspects”
3.5 “Relate the 'ideal' architectural scheme into an actual development

and implementation strategy”

The deliverables 3.1 and 3.3 are related to the Business Domain, which is used to align strategic objectives and tactical demands. This provides a common understanding of the organization described by:


  • Deliverable 3.1 deals with business processes, which constitute the core business and create the primary value stream.

  • Deliverable3.3 deals with  the management processes, which govern the operation of a system,

In the present document we will analyze deeply this domain with specific focus on the business processes.

Deliverable 3.2 is related to the Information Systems Domain, i.e. the conceptual organization of the effective S-DWH which is able to support tactical demands. This describes models, policies and rules that govern which data is collected, and how it is stored, arranged, integrated, and put to use in a S-DWH.

Deliverable 3.4 is related to Technology Architecture, which is the combined set of software and hardware able to develop and support IT services.
The first four deal with aspects of a  S-DWH architecture framework, which defines how to create and use a S-DWH. This deliverable, the fifth, deals with the “ideal” architectural plan and therefore is composed by the most relevant parts of the previous deliverables organized in the right order.
