Cascade DataHub Uses Ajax to Put Live Data On Cell Phone Displays
JavaScriptSearch The Cascade DataHub from Cogent Real-Time Systems puts dynamic data into a web page without using .NET programming, ActiveX objects, or Java applets. The Cascade DataHub's new built-in web server uses client-side scripting to update data on a web page in real time. Live trading or financial data from a streaming data source or Excel spreadsheet can be viewed in any web browser, PDA, or cell phone capable of using HTML and Javascript. Wi-Fi enabled devices can even access data without accruing cellular connection charges. "Today's professional wants always-on access to his data," said Andrew
Thomas, president of Cogent Real-Time Systems. "Ajax by itself is a
leap forward in web technology, and when you connect it to a real-time
data feed through the Cascade DataHub, you get a truly dynamic system." The Cascade DataHub is a memory-resident real-time middleware
application that collects data from one or more sources and distributes
it to any number of clients. It can connect to an ordinary Excel
spreadsheet, allowing it to share data over a network or the Internet
with other spreadsheets. Now, with its built-in web server and Ajax,
the Cascade DataHub can send data from Excel to a web page on a PC or
cell phone, in real time.
