In our ongoing Data Vault Friday series, our CEO Michael Olschimke addresses a question raised by a member of our audience.

“We load a Same-As-Link (SAL) from multiple sources to deduplicate records across these source systems. How do you define the record source? The data is not clearly coming from only one source.”

In this insightful video, Michael delves into the intricacies of handling Same-As-Links (SAL) when loading data from multiple sources for the purpose of deduplication. The specific challenge raised about defining the record source when data is sourced from multiple systems is a common issue in many projects.

Michael shares best practices, providing clarity on the intended use of the record source and offering guidance on how to avoid common pitfalls associated with its misuse. The discussion sheds light on the importance of correctly defining the record source to ensure accurate data lineage and enhance the effectiveness of deduplication efforts.

For those navigating the complexities of deduplication in a multi-source environment, this video offers valuable insights and practical recommendations.
