n the previous chapter, you implemented a selectable list of departments for the BalloonShop web site. However, a product catalog is much more than that list of departments. In this chapter, you ll add many new product catalog features, including displaying product lists and product details. Review Figures 4-1, 4-2, and 4-3 to get a feel for the new functionality you ll implement in this chapter. More specifically, in this chapter, you will Learn about relational data and the types of relationships that occur between data tables, and then create the new data structures in your database. Understand how to join related data tables, how to use subqueries, how to implement paging at the data tier level, and even more theory about T-SQL functions and techniques. Complete business tier functionality to work with the new stored procedures, including stored procedures with input and output parameters, and use simple data structures to pass requested data to the presentation tier. Create new Web Forms and Web User Controls to show your visitors details about your categories, your products, and more. Yep, that s a lot of material to get through! Take a deep breath, and let s get started!

Indicates the title of the page. This attribute is often used by navigational controls to display the title for the URL. Indicates the URL of the page that this node represents. Specifies the description of the destination page. You can use this description to show ToolTips. While using security trimming, this attribute specifies the roles that are allowed to access this page.

Given the new functionality you are adding in this chapter, it s not surprising that you need to add more data tables to the database. However, this isn t just about adding new data tables. You also need to learn about relational data and the relationships that you can implement between the data tables, so that you can obtain more significant information from your database.

It s no mystery that a database is something that stores data However, today s modern relational database management systems (RDBMSs), such as MySQL, PostgreSQL, SQL Server, Oracle, DB2, and others, have extended this basic role by adding the capability to store and manage relational data So what does relational data mean It s easy to see that every piece of data ever written in a real-world database is somehow related to some already existing information Products are related to categories and departments, orders are related to products and customers, and so on A relational database keeps its information stored in data tables but is also aware of the relations between them These related tables form the relational database, which becomes an object with a significance of its own, rather than simply being a group of unrelated data tables.

Note Security trimming is a feature that implements role-based security by rendering only the nodes that are allowed for the current user. In other words, a particular <siteMapNode> will be accessible to a user only if the user s role is specified in the roles attribute of the <siteMapNode> element.
