Project Overview: Application Design
The remainder of Part III of the tutorial consists of a series of instructions and exercises that guide you through the completion of a simple contact management system. The system allows users to view and update contact information (contacts and their phone numbers) stored in Caché. The application consists of a .NET Windows Form connected to a Caché database using ADO.NET and the relational interface to the CMP. The database schema and the Windows form have been provided for you. You will only be adding the code that connects the form to Caché.
The application uses ADO.NET's “Disconnected” approach. Here is how it works:
The application creates a DataSet object that mimics the layout of the Caché tables.
Responding to user requests, the application makes changes to the DataSet data.
The tutorial provides a skeleton solution that you can use to complete the instructions and exercises. The tutorial also provides a complete solution that you can install and execute. For instructions on locating and configuring these files, see the Note below.
