Can the Entities declaration be used to intercept field data being read or written to

Where Entities are defined for the database/xdata. Is that all just declarations? Or can I implement Get/Set methods to massage a field before its passed to the client or after its been received from the client.

As an example, The client posts a record. I want to create a fingerprint style field from the other fields. I would prefer to intercept this and work out the value to save for the fingerprint in the Windows server code.

If I cant, then I can obviously use a trigger in the DB to do it. But that exposes the logic.

You need to use the [OnInserting] and [OnUpdating] events to do this.

Don't forget that if you update a field in OnUpdating to add it to the changed column list.

What class are these events in

You create them within the entity and either map them or (easiest) set the [OnUpdating] or [OnInserting] attribute. Take a look at Events | TMS Aurelius documentation
