Answer 1

Domain is the central object for describing the technical characteristics of an attribute of an business objects. It describes the value range of the field. Data Element: It is used to describe the semantic definition of the table fields like description the field. Data element describes how a field can be displayed to end-user.
A domain defines the properties of a data element within ABAP. The properties include the data element type, it's length if required and any restrictions on the values that may be entered into that variable. By defining a domain you can automate and greatly reduce the amount of work required when handling amongst other things user input parameters. Domains also standardise your programs. By using a domain rather than individually defining the variables within your program, any changes to the domains characteristics are automatically passed on to any programs that use that domain
A dataelement is the one which has the information about the field's representation on the screen in the form of FIELD TEXTS, COLUMN CAPTIONS in list outputs of the table contents and the format of the output via PARAMETER IDS and Online field documentation.
