lossless decomposition

What does DBMS decomposition mean? In database management systems, the process of splitting a table into several tables or a relation into several relations is known as decomposition. When we wish to process a specific data set, we use decomposition in DBMS. When we need to guarantee consistency and eliminate anomalies and duplicate data from the database, we use a database management system. It is important to make sure that no data or information is lost during the decomposition process in DBMS. Decomposition Types Two categories of decomposition exist: Lossless Decomposition Lossy Decomposition Lossless Decomposition: What Is It? Lossless join decomposition is the process of breaking down a relation R into relations R1 and R2 so that the original relation R is returned when a natural join of R1 and R2 is performed. This effectively eliminates database redundancy while maintaining the original data. Stated differently, lossless decomposition makes it possible to use joins to recons...
