prep for 70-315 merge projects

i am aware that this exam is due to expire but I have to write the exam and pass it...there are a few things I am blurry on and need to better understand for the exam...where can I find some good information for  VS.NET 2003 for the exam....or perhaps someone can explain for me these things..
data adapter
contraints for ignorefailureonupdate
and the concept with merge modules as opposed to web setup projects

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hi chicabow;

Amazon.com has this book written by  Amit Kalani  and is NOT a Microsoft Press study guide
"MCAD/MCSD Training Guide (70-315): Developing and Implementing Web Applications with Visual C# and Visual Studio.NET (Training Guide) (Paperback)"
http://www.amazon.com/MCAD-MCSD-Training-Guide-70-315/dp/0789728222

The cost of the book if you select Used will cost as low as $3.49 plus shipping which should not be more then $5.00 so for about $8.50 you will get a very good study guide and has exam like question after each chapter and a Final exam with about 75 exam question in the back.

If you query Google for "70-315" you will get allot of links to sites that want to sell you software exam prop but you will also find people who may have posted some study notes.

The DataAdapter is a class that belongs to the ADO .Net Data Provider modle. When instansiated it provides the conduit between the data source and the DataSet in the application. In other words the DataAdapter manages the Database while the DataSet manages the in memory data of the database. Data Providers are specific to a database product for example SqlDataAdapter is used with Microsoft's MS SQL Server while OleDbDataAdapter is used with database that support OleDb interface.

The (ignorefailureonupdate) Do you mean ContinueUpdateOnError: Is a property of the DataAdapter that if set to true, no exception is thrown when an error occurs during the update of a row in the database. The update of the row is skipped and the error information is placed in the RowError property of the row in error in the DataSet. The DataAdapter continues to update subsequent rows. Once the updates have completed you can check the RowError property of all the rows to see which rows were not updataed.

Merge Modules : A merge module is a single package that contains all files, resources, registry entries, and setup logic necessary to install a component. Merge modules cannot be installed alone, but must be used within the context of a Windows or Web Setup Project.

Web Setup projects: install files into a virtual directory of a Web server.
