Which method refers to the way data connects across different types of sheets?

The method that refers to the way data connects across different types of sheets is dimensionality. Dimensionality in Workday Adaptive Planning allows users to structure and organize their data in a way that facilitates multi-dimensional analysis. By leveraging dimensions, such as departments, locations, and time periods, users can create a more flexible and dynamic environment where different sheets can interact with one another seamlessly. This interconnectedness enhances the ability to perform complex analyses and reporting based on various business dimensions, making it easier to gain insights from the data.

The other options do not specifically address the relational aspect across different types of sheets. While flexibility pertains to the adaptability of the model and performance relates to how efficiently data processes, neither directly refers to the structural connections that dimensionality provides. Account visibility focuses on the accessibility of accounts for users and reporting, which is also unrelated to the core idea of data connectivity across sheets.
