Structures of a Database

Flat File

The simplest model for storing data.

Consists of a single, two-dimensional table of data elements.

Each row in the table is a record and each column of the table is a field.

Hierarchical Database

Allows one-to-one and one-to-many relationships.

Offer lightning quick searches.

Utilize a minimum amount of disk space for storage.

Networked Database

Uses a mesh-like structure to offer the additional capacity to define many-to-many relationships.

Rarely used today for business, consumer, and other mainstream database applications.

Remain in use only for specialized applications.

Relational Database

Stores data in a collection of related tables.

Each table is a sequence of records similar to a flat file.

All the records in a table are of the same record type.

Dimensional Database

Organizes relationships over three or more dimensions.

Sometimes referred to as a multidimensional database.

Each field is contained within a cell that can be accessed directly from a query or from following a relationship.
