Hi Sridevi Sudunaguntla ,

context mapping-> means mapping between different contexts

ie suppose if we are creating a node in the component controllet and if we want to use that node in view a and view b, then we have to map this node from component controller to the required view.. this mapping of context nodes is called context mapping..for context mapping, create nodes in compcontroller.. tehn go to view-> context-> tehn drag and drop required node from component controller to the view ..

data binding-> means binding the data from nopde to the ui elements or viceversa... after the nodes are created in indudual views or after context mapping.. we have to bind these nodes to the ui elements... suppose we have an input field and we want to read that,, so we have to bind the input field to an attribute in the node.. this binding is called.. data binding.

hi sridevi....

context mapping:

you might create a node in the component controller and wish to use it in your view... in that case you will just drag the node from the context of component controller to your view context. this is known as context mapping.

data binding:

for some fields in your layout, like input field, you need to give the valu through the attributes and nodes in your view context. this is known as data binding.
