A data model in Excel is defined as a collection of related tables used for advanced data analysis. This definition highlights the capability of Excel to work with multiple interrelated datasets, allowing users to create complex queries and perform sophisticated analyses. By establishing relationships between different tables, users can harness the power of data modeling to extract insights that would be challenging to achieve with just a single table.

This approach not only enhances data organization but also optimizes performance, especially when dealing with large datasets. The functionality supports features like Power Pivot, which enables users to build more comprehensive and dynamic reports or dashboards based on multiple sources of data, leveraging the relationships defined within the model.

Each of the other options describes aspects of data management and analysis but does not capture the essence of what a data model entails in Excel. A single table does not provide the relational aspect needed for advanced analysis, while a collection of data points over time lacks the structure needed for meaningful relationships. Additionally, a model predicting trends focuses more on forecasting than on the underlying relationships and data organization that a data model represents.
