Classes

ConnectionUpgraderNotifier

A static helper class to ensure all connections upgrade their models from a client notificaion

CustomUpgradeHelper

SQLWrapperUpdater

A class that can be implemented by any custom sql wrapper that should be dynamically generated or updated on every database upgrade

For instance the system QUERYNAME canvas query is regenerated every time the system is updated to account for any new entities and their changes

Typically this implementation can also implement IBaseDataSetProcessorWithDBSave to make sure this is automatically run when dependant items are modified too

Interfaces

IConnectionModelChanged

This is implemented by the connection type that directly connects to a database.

When the client directly connected to a database upgrades the database, it needs to notify the connection the database has been upgraded so it can recompile the model

The client itself does not distinguish between the database or service connection types, so this is implemented internally to the db connection type

ICustomUpgrader

ICustomUpgradeVersionHandler

With custom addins this provids a mechanism to record version numbers representing the state the database is in, and if upgrades are required
