Decomposition is a process of dividing a relation into multiple relations to remove redundancy while maintaining the original data. In this guide, you will learndecomposition in DBMSwith the help of examples. Types of decomposition: 1. Lossless decomposition 2. Lossy decomposition 1. Lossless decompos...

file management system/ C6160Z Other DBMSA frequency decomposition technique is suggested for very large archivable databases. Modern large databases intended for use in a highly interactive and responsive environment face serious performance and availability problems caused by prolonged archiving and back ...
Applications require fine-grained access control (FGAC) supported by DBMSs themselves. Though much literature has referred to the FGAC, its key problems still remain open. Thus, we develop a FGAC-QD model based on query decomposition strategy with incorporating two notions of authorization rule and...
