摘要：Nesting of relations is very much essential for many database representations in reality. Nesting of relations tends to reduce the data redundancy in the relations. It helps in dropping certain constraints in normalization which tend to omit certain sensitive data when tried to be normalized. Query processing or conversion of data repositories, as required, can be easily being tackled by the aid of this maintenance. Addressing of certain conditions about the commuting properties between different relations is dealt. It has been proved that the maintenance of databases with respect to multivalued dependency is enough for nesting that relation, as required. Multivalued dependency, though omits the rule of being in accordance to normalization, is very much useful to preserve sensitive data relations. More prominently weak multivalued dependencies are being maintained among the relations, where each relation is aimed to be nested with other relations without loss of generality. Certain inference system is being developed with different notations and implications posed on it, for studying multivalued dependent data, that is being nested. Complementation rule, which on being implied to the database, makes the relation to be easily decomposed into smaller relations. Axiomization is being tested on weak multivalued dependent relations, which have been nested.
