DBMS | Lossless Decomposition: In this tutorial, we will learn about Lossless Decomposition, the conditions to achieve Lossless Decomposition, and its advantages and disadvantages.
Dependency Preserving Decomposition Examples Let suppose a relation R (P, Q, R, S) with a set of functional dependency FD = (P→Q, Q→R, R→S). In the given set FD, there is no partial dependency. As a consequence, this relation is in 2NF. The relation R (P, Q, R, S) is...
Query Decomposition, Optimization and Processing in Multidatabase SystemsOne way of achieving interoperability among heterogeneous, federated DBMSs is through a multidatabase system that supports a single common data model and a single global query language on top of different types of existing systems...
