Platform calculation methods
InfoSum Platform may use estimates or actual queries to calculate the results of your queries. This article describes where estimates or actual queries are used on the Platform.
Estimates and actual queries use differential privacy, which will add a small, intentional error margin to all results. By design, users cannot get around the differential privacy applied to actual queries by tactically running many queries.
Some queries will run faster due to system caching - this does not indicate estimates are being used in place of actual queries. No Personal Identifiable Information (PII) is ever cached.

Analyze |
|
|
Connection List |
Uses estimates initially, while actual query runs in the background. Automatically calculated between datasets you own upon new dataset publish events. |
|
Connection Grid |
Uses estimates. |
|
Attribute Affinity |
Uses actual queries run to a list of significant attributes. |
|
Query Tool |
Uses actual queries. Note that the Aggregate function runs more then one actual query. |
|
Activate |
|
|
Activations |
Rounded - Based on the de-duplicated row count of records (not an actual query but also better than an estimate) |
|
Discover |
|
|
Discovery |
Same as the row count from the dataset list - based on the row count at publish (rounded). Not a query but not an estimate. |
|

|
|
Platform API |
Same as for InfoSum Platform. |
Multi-key matching
If you choose to match on multiple keys, a match on any key counts toward the audience total (with multiple matches for a record counted only once) because it uses the OR function. If the datasets contain duplicates, changing the order of the keys can change the count total. For information, see key override and using Segment Builder.
