he following is not a component of data warehouse:Question 29Answera.Lightly summarized datab.Metadatac.Component keyd.Current detail data

The component that is not part of a data warehouse is c. Component key.

Here's why:

a. Lightly summarized data: This is a component of a data warehouse. It refers to data that has been processed and organized in a way that makes it easier to understand and analyze.

b. Metadata: This is also a component of a data warehouse. Metadata is data about data. It provides information about the other data in the warehouse, such as where it came from, when it was last updated, and how it is formatted.

c. Component key: This is not a standard component of a data warehouse. While keys are used in data warehousing, specifically primary keys and foreign keys to establish relationships between tables, the term "component key" is not standard in data warehousing.

d. Current detail data: This is a component of a data warehouse. It refers to the most detailed, current data available in the warehouse.
