In many web data integration tasks, the desired data is located on a web page that is accessible only through a form that needs to be completed to access detailed information. WebQL is capable of automatically populating such variable data to gain access to the “deep” Web. The data can then be extracted by WebQL and transformed into an actionable format to be used in a variety of analytical operations.
WebQL features novel URL schemes that allow for enhanced flexibility when accessing data sources that are external to WebQL. WebQL also support XML data of arbitrary size, and APIs for embedding WebQL in C, Java or .NET programs.
WebQL is driven by a sophisticated programming language similar to standard SQL. The language has a number of operations designed to simplify complex data integration tasks. By providing a virtual database layer, WebQL shields developers from the complexity of specific data formats and network protocols. WebQL programmers can use their existing SQL skills to access, transform and integrate data with minimal effort. WebQL can also be operated by less technical users through WebQL Desktop. In addition to licensing the WebQL software for deployment in a customer’s environment, QL2 Software has solutions and will develop customer solutions built using WebQL technology on behalf of its customers, and host them in the company’s secure online data center.
