Which parameters in a query allow for aggregation?

In the context of querying data, particularly in systems like Appian, the parameters that support aggregation are identified as groupings and measures. Groupings allow you to specify the categories or distinct values for which you want to aggregate data, while measures represent the numerical values that you want to perform calculations on, such as sums, averages, counts, etc.

Utilizing these two elements together, you can generate insightful summaries of your data. For example, if you group sales data by region, 'region' would be your grouping, and the total sales amount would be your measure. This allows the system to compute total sales per region, giving you a clear view of performance across different areas.

Other parameters mentioned, such as pagingInfo and dimensions, facilitate aspects of data retrieval but do not directly relate to the process of aggregating data. PagingInfo is concerned with how much data is retrieved and at what interval, while dimensions typically help describe the structure of the data rather than aggregating it. Similarly, recordType is more about the type or schema of the records rather than the aggregation of values. Therefore, understanding the role of groupings and measures is crucial for effectively working with aggregated query data in Appian.
