⭐ Core Definition: Flat file database

A flat-file database is a tabular flat-file in which each record is semantically independent – can meaningfully be interpreted and manipulated independent of other records of the table. The term flat loosely refers to data that is record-based and sequential yet lacks more complicated aspects such as nesting, relationships and metadata (with the exception of column headers). Relationships can be inferred from the data, but the format does not provide special accommodations for relationships.

Flat file database in the context of Table (database)

In a database, a table is a collection of related data organized in table format; consisting of columns and rows.

In relational databases, and flat file databases, a table is a set of data elements (values) using a model of vertical columns (identifiable by name) and horizontal rows, the cell being the unit where a row and column intersect. A table has a specified number of columns, but can have any number of rows. Each row is identified by one or more values appearing in a particular column subset. A specific choice of columns which uniquely identify rows is called the primary key.
