Binary Relational Operations

Digital Electronics: Principles, Devices and Applications is a comprehensive book covering, in one volume, both the fundamentals of digital electronics and the applications of digital devices and integrated circuits. It is different from similar books on the subject in more than one way. Each chapter in the book, whether it is related to operational fundamentals or applications, is amply illustrated with diagrams and design examples.

In this paper, we propose a new probabilistic relational database model, denoted by PRDB, as an extension of the classical relational database model where the uncertainty of relational attribute values and tuples are respectively represented by finite sets and probability intervals. A probabilistic interpretation of binary relations on finite sets is proposed for the computation of their probability measures. The combination strategies on probability intervals are employed to combine attribute values and compute uncertain membership degrees of tuples in a relation.

The basic set of operations for the relational model is known as the relational algebra. These operations enable a user to specify basic retrieval requests. The result of a retrieval is a new relation, which may have been formed from one or more relations. The algebra operations thus produce new relations, which can be further manipulated using operations of the same algebra.

For information to be saved permanently on a disk, you can use a file. The file is a stream of characters or a flow of related data. Streams enable you to write and read bytes to and from a storage medium, respectively. Streams can be used to perform fundamental operations such as read and write. This chapter introduces the concept of the file input and output operations. It explains the process of reading and writing in the text files and the binary files. It also explains the process of browsing through the Windows File System. ...

Chapter A Preliminaries of Real Analysis A principal objective of this largely rudimentary chapter is to introduce the basic set-theoretical nomenclature that we adopt throughout the text. We start with an intuitive discussion of the notion of “set,” and then introduce the basic operations on sets, Cartesian products, and binary relations.
