The SearchCatalog stored procedure will receive the words to search for as separate INPUT parameters. But wait, how do you know how many keywords the search string will contain Well, you don t, and the workaround is to assume a maximum number of keywords. In this case, you ll have five input parameters named @Word1 through @Word5. These parameters will have a default value of NULL, so the business tier won t have to supply values for all of them if the visitor is searching for fewer than five words. The obvious disadvantage is that you ll always have a maximum number of keywords that can be accepted (five words, in this example). If a visitor ever introduces more than the maximum number of words, the additional words are simply ignored the business tier doesn t send them to the stored procedure at all. This suggests the second drawback: The business tier needs to know about the data-tier logic (regarding the maximum number of allowed words); this is a data-tier limitation that has to be handled by the business tier.

In this case, the web page accesses the shared GetInfo() method through the class name and doesn t need to create an object:

Why not just look at the DataReader and DataSet as you go along Why put this interlude first These are good questions, but they have a simple answer (borrowed from the world of Perl) For every data-related task you ll be looking at over the coming chapters, you can follow this motto: There s More Than One Way to Do It But all of these ways stem from how the DataReader and DataSet work If you don t look at these objects now and see the situations in which they re useful, you ll be less likely to choose the right option when building data-driven pages of your own..

Deciding when to use instance methods and when to use shared methods is part of the art of object-oriented design, and it takes experience. Shared methods impose additional considerations namely, your class must be stateless (a concept described in the

Note You might not like the limitation about the number of words you can search for in the database. However, if you set the limit high enough, the visitors are not likely to feel this limitation. Even Google has (at the moment of writing) a maximum number of allowed search words (ten), and we haven t heard anyone complaining about this, so far.

following section), which means it can t hold on to any additional information in member variables. If it does, it risks a potential conflict if more than one piece of code uses the component at the same time. As a rule of thumb, use instance methods if you need to be able to create several instances of your class at the same time. For example, instance methods make sense for the SqlConnection class, because you might choose to open a connection to several different databases for one operation. Instance methods are also the best choice if you want to configure an object once and use it several times. For example, the SqlConnection class lets you set the connection string and then open and close the connection as much as needed. On the other hand, consider shared methods if your methods perform a single, discrete task that doesn t require any initialization. Examples include the calculations in the Math class, and the business tasks (such as registering a new customer) in a high-level business component.

This chapter covers the following topics: How to iterate through a DataReader Some useful properties and methods of the DataReader How the DataSet works with a DataAdapter How to iterate through a DataSet How to build a DataSet from scratch How to set the SqlDataSource to access a database as a DataReader or a DataSet Differences between the DataReader and DataSet Tips for coding DataReader and DataSet access

The SimpleTest classes provide functionality through public methods. If you re familiar with class-based programming (as described in 4), you ll remember that classes can also store information in private member variables and provide property procedures that allow the calling code to modify this information. For example, a Person class might have a FirstName property. When you use properties to provide access to member variables, you re using stateful design. In stateful design, the class has the responsibility of maintaining certain pieces of information. In stateless design, no information is retained between method calls. Compare the earlier SimpleTest class, which uses stateless design, to the stateful SimpleTest class shown here:
