How does the JavaServer Pages technology work?
JSP pages use XML tags and scriptlets written in the Java programming language to encapsulate the logic that generates the content for the page. It passes any formatting (HTML or XML) tags directly back to the response page. In this way, JSP pages separate the page logic from its design and display.
JSP technology is part of the Java technology family. JSP pages are compiled into servlets and may call JavaBeans components (beans) or Enterprise JavaBeans components (enterprise beans) to perform processing on the server. As such, JSP technology is a key component in a highly scalable architecture for web-based applications.
JSP pages are not restricted to any specific platform or web server. The JSP specification represents a broad spectrum of industry input.
The next generation of data warehousing is real-time or active data warehousing. An active data warehouse also implies near real-time analysis. The key is to get large volumes of data into the data warehouse for next-day analysis. For example, many e-business executives want to see reports on the previous day’s Web activity. But this often involves corralling gigabytes of data. The technologies to support active data warehousing can be complex. But companies that want and need to translate data into action quickly will rely on active or real-time data warehousing tools and techniques to achieve this goal.
