Aggregate—ArcGIS Pro Documentation

Discussion. Use the Aggregate function to aggregate variable values from a multidimensional raster over a given variable. For example, if you have daily precipitation data, you can determine the monthly average precipitation value. This function creates a raster object that is the aggregation of the input multidimensional raster.

How to determine aggregates when entities are shared? Ask Question Asked 7 months ago. Active 5 months ago. Elect some object as the aggregate root, and adjust its interface so that the aggregate can provide all of its services through that object. Because all interaction happens through it, the root can enforce the invariants of the group.

c# How To Determine Aggregate Root Domain Driven

Aggregate applies to composition. Here is why: Let's take your own example. You have an abstract class User, and then you have these specializations of User: Administrator, Manager, Maintenance. Now, these four are not in an aggregate-aggregate-root relationship. But, they are all aggregate roots. Or in other words, each is aggregate root.
