As a computer science term, data binding is the substitution of a real value in a program after it has been compiled. For example, during compilation a compiler can assign symbolic addresses to certain variables or instructions. When the program is bound, or linked, the binder replaces the symbolic addresses with real machine addresses. The moment at which binding occurs is called "bind time" or "link time." In dHTML, data binding allows the client to look into a database and retrieve the content. This data can be automatically displayed in your table using the HTML data binding extensions, or you can manipulate the data with a script. Currently, dHTML data binding is only supported by Microsoft Internet Explorer.
