Data Warehouse and ETL Testing Services
Our principal goal is to catch defects (e.g., database design, source data, ETL process, data quality) early, to help reduce your costs and lower your risks.Request for QA Services
Data warehousing continues to gain importance as organizations become more fully aware of the benefits of data-driven, business-decision making. One primary element of an efficient data warehouse system is an ETL process that can reliably extract, transform, cleanse, and load data from source systems (see Figure 1) during normal operation without impacting overall performance, scalability, or reliability.
All too often, however, data quality defects are introduced much earlier, during the multiple stages of warehouse development. Fast-track projects that move rapidly through development and implementation can be especially prone to the unintentional injection of defects.
QA Mentor’s Data Warehouse SQA and ETL Testing Services provides your team with the necessary expertise, oversight, and hands-on efforts to test throughout the requirements, design, and deployment cycles with an eye to discover defects before they even occur. Our goal is to provide your team with an overall Software Quality Analysis process (SQA – e.g., DWH testing strategy / approach, system test plan, test cases, test schedule, defect reports, and metrics). Our principal goal is to catch defects (e.g., database design, source data, ETL process, data quality) early, to help reduce your costs and lower your risks.
To address these objectives, QA Mentor’s service presents new ideas for a beginning-to-end data warehouse lifecycle quality process.
