Displaying RSS Feeds - A Look at RssFeed Version 1.9   28 Sep 2005 00:00 GMT

Over the past several years one of the growing trends in the Internet space has been syndication, the process of providing a site's content through a machine-readable file (i.e., an XML-formatted file). Once a site's content is marked up in a machine-readable format, there are a multitude of ways that that data can begin to be utilized. The most common way is through aggregators, which are programs designed to periodically cull through a list of syndication feeds and download any new content. (There are a variety of aggregator programs, from desktop based ones like RssBandit to online ones like BlogLines and My Yahoo!.) More interestingly, the site content, now able to be parsed by a program, can more easily be searched, customized, categorized, and analyzed. And, as we'll see in this article, content from another site can easily be injected into your own site by having your ASP.NET pages retrieve the remote syndicated content, parse it, and display it.

Site syndication has been an idea that has been around for over a decade, but didn't enjoy wide-spread adoption until bloggers started using it to make it easier for their friends and readership to easily receive new content. Since then, many large websites have jumped on the syndication bandwagon, including ABC News, ESPN, Yahoo! News, Microsoft MSDN, and so on. There are a couple of syndication standards used, the most popular (at this time) being RSS version 2.0, where RSS stands for Really Simple Syndication. There are other syndication formats, however, which are discussed briefly further on in this article.

In a previous article on mine, A Custom ASP.NET Server Control for Displaying RSS Feeds, I looked at using a free, open-source ASP.NET server control that I created in order to display syndicated content from another site on an ASP.NET website. This server control, called RssFeed, has recently been updated to include some new, neat, snazzy features. In this article we'll take a quick look at RssFeed and then highlight some of its new features. Read on to learn more!

Returning a Comma-Delimited List of Related Records   21 Sep 2005 00:00 GMT

In any non-trivial database design, there are related entities within the system. Some entities may share a one-to-many relationship, others a many-to-many relationship. For example, a student database may have a Faculty table that lists its teachers, along with a Students table that contains a row for each student. The Students table may have an AdvisorID, which serves as a foreign-key back to the Faculty table, indicating the student's academic advisor. In such a case there's a one-to-many relationship between faculty and students - a faculty member may have an arbitrary number of students that she's advising. Additionally, there may be many-to-many relationships, such as a Classes table that enumerates the classes offerred, along with an Enrollments table that maps students to classes. The Enrollments table provides a many-to-many relationship between students and classes, since each student may be enrolled in multiple classes and each class may have multiple students enrolled.

In either type of relationship, there are times when we may need to provide a comma-delimited list of related records. For example, the dean may want to see a report that lists each faculty member followed by a comma-delimited list of students she is advising; a professor may want a print out of the list of classes he's teaching, followed by a comma-delimited list of students taking the course that semester; an accountant for the school might want to see a list of students, showing a comma-delimited list of each class that student is currently taking. For example, the dean's report may have the following output:

Faculty	Students Advising
Scott	John, Paul, George, Ringo
Jisun	Tito, LaToya, Michael, Janet
Sam	Carl, Johann, Christoph
Dave	Not advising any students

To provide such functionality there's basically two approaches that can be taken:

1. Retrieve the data using the typical JOIN notation, returning a row for each pair of matching results. Then, in the 'client' (i.e., your server-side web application), combine the returned data into a comma-delimited list, or
2. Formulate the comma-delimited list in SQL

In this article we'll briefly examine the first approach and then delve more deeply into the second. Read on to learn more!
