  • 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. ...
