Hi,

I want to build an BL, in adapter scenario.

I need the BL functionality would be accessible only via manager classes.

How can i achieve, that the adapter be not instantiable from the client side?

Thanks

Gabor

You use the database generic project in your gui tier and bl tier you use the database specific project in your bl tier

this means that the gui can't create a dataaccessadapter object, it has to call BL methods. So, the GUI can create new entity objects, fill them with data and then call for example CustomerManager.AddCustomer(entity); which is part of teh BL tier. In that method the entity is then checked and saved, making it impossible for the gui to do things with the database unless the BL tier's methods are called.

Oh yes. Thanks. Sometimes the most obvious things have to ask

Frans,

Ok, now the UI gets only my BL classes.

Now how can i narrow the entities functionality too, ie. i don't want, the clients get access to the GetRelationInf_ RelattedEntities_ and similar entity's functionality, because on don't need them. I will manage all the functionality in the BBL managers.

Thanks, and apologize for the questions, that are so obvious for more experienced peoples.

These methods produce filters, not entities. You need these in your code.
