Which layer focuses on enhancing data accessibility?

The layer that focuses on enhancing data accessibility is the Access layer. This layer is designed to provide users with the ability to retrieve and interact with data efficiently and conveniently. It serves as the interface between the data stored in the database and the end-users or applications that need to use that data.

In a data warehousing context, the Access layer often includes tools and functionalities that enable querying, reporting, and analysis. By promoting data accessibility, this layer allows users to generate insights and make data-driven decisions effectively. It is crucial because it ensures that users can easily find, analyze, and visualize the data they need, improving overall data usability in an organization.

Understanding the importance of accessibility helps organizations leverage their data assets and enhances the value derived from data analysis and reporting activities.
