share data between them and they depend on each other only to take input and give output. In layered architecture of Network Models, one whole network process is divided into small tasks. Each small task is then assigned to a particular layer which works dedicatedly to process the task only. Every layer does only specific work. I have chooses application layer from the OSI model because the world experiences the Internet through the use of the World Wide Web, e-mail, and file-sharing programs. These

relationship between two entity sets with keys A and B, respectively, and suppose that R has (among others) the FDs A → B and B → A. Explain what such a pair of dependencies means (i.e., what they imply about the relationship that the relation models). Answer 19.1 1. Let R be a relational schema and let X and Y be two subsets of the set of all attributes of R. We say Y is functionally dependent on X, written X → Y, if the Y-values are determined by the X-values. More precisely, for any two
