Data-driven pages are primarily used for what purpose in ArcGIS?

Data-driven pages in ArcGIS are a tool designed to generate dynamic layouts based on datasets, allowing users to create a series of map pages that reflect different segments of the data being visualized. This feature is particularly useful for managing extensive datasets where each map page can represent a unique area or attribute derived from the underlying data.

The primary advantage is that it automates the creation of multi-page map series efficiently, saving substantial time and effort compared to manual map creation. For instance, when working with a dataset that includes numerous geographic features, such as municipalities or districts, data-driven pages enable the automatic generation of a separate map page for each feature, ensuring consistency across all maps while allowing for individual customization.

In contrast, creating static maps generally involves manually designing each map without the benefits of automation offered by data-driven pages, and storing user logs and processing large datasets pertain to other functionalities within ArcGIS that do not leverage the dynamic and automated nature of data-driven pages.
