What is defined as the lowest object in the hierarchy during extraction?

The concept of the lowest object in the hierarchy during data extraction is best represented by the term "Root Object." In the context of data extraction, the root object refers to the foundational element from which all other data elements are derived or related. It typically contains the most granular level of detail and serves as the base for building relationships with other objects in the data hierarchy.

By identifying the root object, analytics professionals can accurately navigate through the data structure, facilitating effective extraction and analysis. This foundational aspect is crucial in defining the overall data model and determines how data is organized, accessed, and transformed throughout the extraction process.

The other terms, while relevant in various contexts within data handling, do not align with the specific notion of being the "lowest object." For instance, a source object generally refers to the origin of the data rather than its position in a hierarchy, and a derived object usually pertains to data that has been calculated or generated based on other data. A canvas object could refer to a visualization or representation in analytics but does not define a hierarchical position in data extraction.
