The Semantic Web is a web of data. There is lots of data we all use every day, and most of it is not part of the web. I can see my bank statements on the web, and my photographs, and I can see my appointments in a calendar. But can I see my photos in a calendar to see what I was doing when I took them and on a map so I know where I took them? Can I see bank statement lines in a calendar? The answer, right now, is no.

A common need in SQL is the ability to iterate over a list as if it were an array. In SQL it is not possible to declare arrays, unlike other programming languages such as ColdFusion, ActionScript and Java. Fortunately, there is a way around this problem: use a User-Defined Functions (UDFs) to create a tabular version of the data. Arrays are, after all, essentially tabular data (at their simplest, one dimension level). Read more – ‘SQL User-Defined Function: ListToTable’.
Rich Internet Applications are just the beginning. A key trend taking place throughout the Web industry is the urgency to integrate disparate systems and software tools to reduce costs, increase developer productivity, reduce the need for manual processing and intervention in transactions, and decrease time to market. To achieve these objectives, organisations have endorsed the adoption of standards-based systems combined with the migration to Web Services and Service Orientated Architecture. This has led to a requirement to create a consistent and intuitive interface to applications, data and services. The immediate goal of these efforts is to provide simpler, quicker and more efficient access and processing of information. Read more – ‘Future Directions for Rich Internet Applications’.
A new breed of Web-based data integration applications is emerging across the Internet. Colloquially known as mashups, their popularity stems from the emphasis on interactive user participation and the manner in which they aggregate third-party data. A mashup is a website or web application that seamlessly combines content from more than one source into an integrated experience. Mashups are an exciting genre of interactive Web applications that are characterised by, and draw upon, content and functionality retrieved from external data sources to create entirely new and innovative services. They are a hallmark of the second generation of Web applications widely known as Web 2.0. Read more – ‘Wise Up to Mashups’.
