Developer Glen Smith from AquaQ looked into WebSockets and kdb+ using the latest version of HTML. In his blog post, Glen demonstrates how to make a kdb+ database accessible beyond the console so anyone with a device that has a modern web browser can access the data.

The aim of this post is to introduce the idea of using HTML5 and kdb+ together. HTML is a markup language used to build web pages and HTML5 is the latest version. It comes with many new features but one we will focus on is WebSockets which allows us to easily send and receive data from kdb+.

WebSockets allows web applications to maintain bidirectional communications with server side processes over one TCP socket. The method that was widely used before WebSockets is AJAX. AJAX consisted of continually polling a connection to receive new data, opening a new connection, downloading data and then closing the connection. With WebSockets, once the connection between the client and server is established it stays open and data can be sent down to the client in real time. kdb+ has been supporting WebSockets since v3.0.
