What is SCD / Slowly Changing Dimension | Data Engineering Tutorial | Data Engineering Concepts
Slowly Changing Dimension (SCD) is a concept used in data warehousing to describe how dimensions in a database evolve over time. This term is commonly used in the context of dimensional modeling, where a dimension is a way of categorizing data in a database.
In an SCD, the data in a dimension may change over time, but not necessarily at a fixed rate. This can make it difficult to maintain accurate data in the database, as the information may become outdated or incorrect over time. To address this issue, several techniques have been developed to manage slowly changing dimensions, including SCD Type 1, SCD Type 2, and SCD Type 3.
In this video, we will explore the concept of Slowly Changing Dimensions in more detail, including the different types of SCDs and how they are implemented. We will also discuss the importance of managing SCDs in data warehousing and some best practices for doing so effectively.
