WebThe decomposition algorithm for 3NF ensures the preservation of dependencies by explicitly building a schema for each dependency in the canonical cover. It guarantees that at least one schema must hold a candidate key for the one being decomposed, which in turn ensures the decomposition generated to be a lossless decomposition. WebB+ File Organization. B+ tree file organization is the advanced method of an indexed sequential access method. It uses a tree-like structure to store records in File. It uses the same concept of key-index where the primary key is used to sort the records. For each primary key, the value of the index is generated and mapped with the record.
WebA system where every server is independent and uses a centralized DBMS with its own local users is called federated database.

WebA central network authority makes decisions for a centralized network. Decentralized systems have several owners. Decentralization is furthered through distributed systems. Ownership is not a notion in this place. All users are owners and all have equal rights. Every node in decentralized systems makes its own decisions.

Candidate Key is a Super Key whose no proper subset is a super key, i.e. suppose if ABC is a candidate key then neither A, B, C or any of its combination can be super key, hence we can say candidate key is a minimal set of attributes of an R ( Relational Schema) which can be used to identify a tuple of a table uniquely.
