Linux, Powell's Review-A-Day, and RSS (Really Simple Syndication) are highlighted in a discussion of the advantages of an open, standards-based approach for optimal delivery of Web applications to new and different users of phones and personal digital assistants (PDAs). For instance, Scott Stocker, director of Web communications at Stanford University, has deployed an approach based on Linux and MySQL, and JavaServer Pages (JSPs). Java servlets are persistent, while Common Gateway Interface (CGI) programs are not. Javas servlets are available in memory to comply with multiple requests once they have started. Stanford IT is a Solaris/Oracle database environment, but the Java application programming interfaces (APIs), particularly Java Database Connectivity (JDBC), plugged in without much difficulty to the back end. The JDBC API permits Java programs to interact with any SQL-compliant database. Stocker continues to use open source in his latest project, a public events calendar. With the Apache Struts tags, Stocker can concentrate primarily on business logic and presentation layer. Also described is the open, standards-based approaches of Powells, where RSS supports the Review-A-Day service to deliver new book reviews to the Powell's site from various publications. Paul Lipton, technology strategist for Computer Associates International (CA), tells Web managers to scale on the basis of observed Web traffic and Web server performance and to use a comprehensive Web management solution that can concurrently manage from IT, end user, and business user perspectives.
