DATABASE STRUCTURES DATA STRUCTURES
Database structures are the logical data models that describe the relationships among the many individual data elements stored.

DATABASE STRUCTURES THE FIVE FUNDAMENTAL DATA STRUCTURES
- Hierarchical Structure - Network Structure - Relational Structure - Multidimensional Structure - Object-Oriented Structure

DATABASE STRUCTURES HIERARCHICAL STRUCTURE
Hierarchical Structure is where the relationships between records from a hierarchy or treelike structure, all records are dependent and arranged in multilevel structures

DATABASE STRUCTURES NETWORK STRUCTURE
In this model a hierarchical relationship between two record types (representing real-world entities) is established via the set construct. A set consists of circular linked lists where one record type, the set owner or parent, appears once in each circle, and a second record type, the subordinate or child, may appear multiple times in each circle.

DATABASE STRUCTURES RELATIONAL STRUCTURE
The Relational model for database management is a database model based on first-order predicate logic, first formulated and proposed in 1969 by Edgar F. Users directly state what information the database contains and what information they want from it

DATABASE STRUCTURES MULTIDIMENSIONAL STRUCTURE
The multidimensional data model is composed of logical cubes, measures, dimensions, hierarchies, levels, and attributes. The simplicity of the model is inherent because it defines objects that represent real-world business entities

DATABASE STRUCTURES OBJECT-ORIENTED STRUCTURE
is a database management system (DBMS) similar to a relational database, but with an object-oriented database model: objects, classes and inheritance are directly supported in database schemas and in the query language. In addition, it supports extension of the data model with custom data-types and methods.
