The Create( ) method defined by WebRequest that is used in this chapter can generate four exceptions If the protocol specified by the URI prefix is not supported, then NotSupportedException is thrown If the URI format is invalid, UriFormatException is thrown If the user does not have the proper authorization, a SystemSecuritySecurityException will be thrown Create( ) can also throw an ArgumentNullException if it is called with a null reference, but this is not an error generated by networking

Objects can be one of three types: dimension, measure, or detail Business Objects refers to these types as object qualifications

Exceptions Generated by GetReponse( )

A number of errors can occur when obtaining an HTTP response by calling GetResponse( ) These are represented by the following exceptions: InvalidOperationException, ProtocolViolationException, NotSupportedException, and WebException Of these, the one of most interest is WebException WebException has two properties that relate to network errors: Response and Status You can obtain a reference to the WebResponse object inside an exception handler through the Response property For the HTTP protocol, this object describes the error It is defined like this: public WebResponse Response { get; } When an error occurs, you can use the Status property of WebException to find out what went wrong It is defined like this: public WebExceptionStatus Status {get; } WebExceptionStatus is an enumeration that contains the following values:

Exceptions Generated by GetResponseStream( )

A dimension object, denoted by a blue cube, is typically textual information by which users analyze numeric measures, such as product, region, or month A dimension object often comes from the lookup or reference tables within the universe Dimensions are typically character or date information or numeric codes such as product numbers and customer numbers If your data warehouse uses keys for reference information, then your dimension objects will point to a lookup table However, if your universe accesses a transaction system or if meaningful codes and IDs are stored in your fact table, you face a decision whether to point the dimension object to the dimension table or to the fact table Some universe developers will mistakenly point the dimension object to the fact table, trying to reduce the number of joins for performance reasons Others will duplicate the object for each occurrence in a different table Don t do it Create one dimension object that points to the lookup table This makes for the simplest universe for users, who are your primary concern Additionally, you may be able to specify keys for each object that can minimize the number of joins to process a query (see the section Object Keys later in this chapter)

For the HTTP protocol, the GetResponseStream( ) method of WebResponse can throw a ProtocolViolationException, which, in general, means that some error occurred relative to the specified protocol As it relates to GetResponseStream( ), it means that no valid response stream is available An ObjectDisposedException will be thrown if the response has already been disposed Of course, an IOException could occur while reading the stream, depending on how input is accomplished

The following program adds handlers for network exceptions to the example shown earlier:

The terms dashboard and scorecard are often used interchangeably, although there is a difference In its simplest terms, a dashboard is a collection of information, similar to a dashboard in your car It might include A map that color codes where sales are performing well or poorly A gauge chart that shows if expenses are over/under budget A trend line that tracks stock outs

// Handle network exceptions using System; using SystemNet; using SystemIO;
