N-Tier Data Form - Data Access Layer
|
|
|
http://www.developers.ie/docs/Basic%20N-tierExample.zip
This sample shows you how to build an N-Tier data application.
This demonstrates the use of a 3-Tier system, using SQL Server or MSDE as a back end (accessing the Northwind database), a data access layer middle tier, and a data-bound form as the front end.
The front end is a common type of data-bound form and is useful for navigating through records and viewing various levels of detail for the data related to each record.
Application Overview
See how to create a data access layer on the middle tier that will create a DataSet object to be consumed on the front-end.
See how events are used in the back end to provide status information to the front end.
View an example of data binding on the front-end.
See how a single DataSet can be filled with two DataTables and bound to various controls that are kept in sync with each other.
