The Flex Framework provides two sets of containers:MX and Spark.
Spark: offers a level of abstraction between containers and layouts not available in the MX architecture.are separated from layout managemnt and allow for a develope to specify layouts available in the spark,layouts package or create custom LayoutBase-based layouts to manage the size and position of child elements.
MX container:manage the size and position of its children based on specified properties and styles.To modify the layout rules of a MX container class,you often create a subclass of a similar container or the base mx.core.Container class and override methods such as updateDisplayList() and measure().
Three primary approaches to data retrieval

the MXML compiler,also called mxmlc,is the application that compilers ActionScript and MXML files into a SWF file that can be viewed in the Flash Player.When you run or debug a Flex application in Flash Builder, the MXML compiler is invoked and the files are passed to the compiler as an argument to the application.
