The nested set model is a technique for representing nested set collections (also known as trees or hierarchies) in relational databases.. It is based on Nested Intervals, that "are immune to hierarchy reorganization problem, and allow answering ancestor path hierarchical queries algorithmically — without accessing the stored hierarchy relation".
Collections management, which consists primarily of the administrative responsibilities associated with collection development, is closely related to collections care, which is the physical preservation of cultural heritage. The professionals most influenced by collections management include collection managers, registrars, and archivists.
The four relational models are as follows: Communal sharing (CS) relationships are the most basic form of relationship where some bounded group of people are conceived as equivalent, undifferentiated and interchangeable such that distinct individual identities are disregarded and commonalities are emphasized, with intimate and kinship relations being prototypical examples of CS relationship.

The records continuum model. The records continuum model (RCM) is an abstract conceptual model that helps to understand and explore recordkeeping activities. It was created in the 1990s by Monash University academic Frank Upward with input from colleagues Sue McKemmish and Livia Iacovino as a response to evolving discussions about the challenges of managing digital records and archives in the ...
Respect des fonds, or le respect pour les fonds, is a principle in archival theory that proposes to group collections of archival records according to their fonds (according to the entity by which they were created or from which they were received).
Self-categorization theory explains the contexts in which an individual perceives a collection of people as a group and the psychological processes that result from an individual perceiving people in terms of a group. [36] Social identity theory describes how individual identity is shaped by membership in a social group. [37]
The relational model (RM) is an approach to managing data using a structure and language consistent with first-order predicate logic, first described in 1969 by English computer scientist Edgar F. Codd, [1] [2] where all data are represented in terms of tuples, grouped into relations.
In management, the relational view by Jeffrey H. Dyer and Harbir Singh is a theory for considering networks and dyads of firms as the unit of analysis to explain relational rents, i.e., superior individual firm performance generated within that network/dyad. [1] This view has later been extended by Lavie (2006). [2]
