Data hierarchy refers to the systematic organization of data, often in a hierarchical form. Data organization involves characters, fields, records, files and so on. [1] [2] This concept is a starting point when trying to see what makes up data and whether data has a structure.
Using links, records link to other records, and to other records, forming a tree. An example is a "customer" record that has links to that customer's "orders", which in turn link to "line_items". The hierarchical database model mandates that each child record has only one parent, whereas each parent record can have zero or more child records.
Records management taxonomy is the representation of data, upon which the classification of unstructured content is based, within an organization. It may manifest itself as metadata in structured database fields or in folder structures represented to end users from a user interface within a system.
This hierarchy is used as the physical order of records in storage. Record access is done by navigating downward through the data structure using pointers combined with sequential accessing. Because of this, the hierarchical structure is inefficient for certain database operations when a full path (as opposed to upward link and sort field) is ...

Records management professionals in designing comprehensive and effective records management programs. The principles identify the critical hallmarks of information governance, which Gartner describes as an accountability framework that "includes the processes, roles, standards, and metrics that ensure the effective and efficient use of ...
Objects in these languages are essentially records with the addition of methods and inheritance, which allow programmers to manipulate the way data behaves instead of only the contents of a record. Many programmers regard records as obsolete now since object-oriented languages have features that far surpass what records are capable of.
A data structure known as a hash table.. In computer science, a data structure is a data organization and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.
