WHAT ARE THE KEY FUNCTIONS OF DATA LINK LAYER

What is the data modelling?
Data modelling is the method used to define and analyze data requirements needed to support the business processes of a project. The data requirements are recorded as a conceptual data model with associated data definitions.
