Data Warehouse Testing

Description A data warehouse is a composite and collaborated data model that captures the entire data of an organization. It brings together the Data that is Extracted, Transformed and Loaded (ETL) into one single destination. Software testing is predominantly focused on program code, while data warehouse testing is directed at data and information. As a matter of fact, the key to data warehouse testing is to know the data and what the answers to user queries are supposed to be.
This type of testing is getting more and more critical in the business scenario nowadays. The reasons for this are manifold, the prominent ones being increase in Enterprise Mergers & Acquisitions, Data Center Migrations, Increased compliance regulations etc. In this 2 day workshop will get to understand and apply how data warehouse testing is done in a structured and methodical way.

The course is appropriate for both Novice and Experienced Software Engineers under the following category:

  • Software developers
  • Test Engineers
  • Quality Assurance Specialists
  • Project / Test Managers
  • Project / Test Leads

Participants are expected to have basic knowledge on software Testing.


Learning Objectives

After the completion of the course, the participants would be able to:

  • Review the fundamental concepts of data warehousing and its place in an information management environment.
  • Learn about the role of the testing process as part of software development and as part of data warehouse development.
  • Learn about test strategies, test plans and test cases – what they are and how to develop them, specifically for data warehouses and decision support systems
  • Create effective test cases and scenarios based on business and user requirements for the data warehouse
  • Plan and coordinate usability testing for data warehousing
  • Conduct reviews and inspections for validation and verification
  • Participate in the change management process and document relevant changes to decision support requirements
