A join is a temporary relationship that you create between tables in database query.
Parallel join: split the pair to be tested over several processors of computer is the part of join and then the result is merged back to have the output.
what do u mean by lossiess join in dbms
join by itself
The advantages of parallel DBMS include improved performance and scalability, as it allows for parallel processing of queries across multiple servers or processors. This can result in faster query execution and the ability to handle larger data volumes. However, the disadvantages include increased complexity and cost of implementation, as well as the need for specialized hardware and software to support parallel processing. Additionally, parallel DBMS may require additional effort for administration and maintenance.
A distributed database management system (DDBMS) manages databases that are stored on multiple computers, often in different locations. A parallel database management system (parallel DBMS) uses multiple processors to perform operations on a single database, improving performance by dividing tasks among these processors. In essence, DDBMS focuses on data distribution and replication across different sites, while parallel DBMS focuses on high-speed data processing using multiple processors.

In DBMS the data is stored in the form of table . Each row in DBMS is known as tuple.
