AMF uses code data types such as Byte (8 bit), Int (16 bit), and many others. With the release of ActionScript 3.0, Adobe updated AMF: it is now called AMF3 (the older version now being referred to as AMF0), and it supports more data types. Working with unformatted binary data has significant advantages: the speed of communication across the wire is much faster, it needs less memory from the client computer, and it reduces processing time over HTTPService or WebService. Although connecting to AMF services is usually not provided through APIs, you may use it to retrieve data from your own local database or server as part of your data sources to your mashup. Flash provides builtin AMF-based APIs such as the following:
