Database - Structures
Data Structures are made of Files.
Files are a collection of Records.
Records are made up of Fields.
A Flat File Database includes a Single Table and is inefficient.
Anomalies (problems): Insertion, Update and Deletion
There are Relational Databases, which have more than one table, which means you have to link the tables in a relationship using Keys.
A Key is a unique identifier. It only belongs to you.
Relational Databases are more complicated.
