Essential Parts of a Database and Data Retrieval Methods
Databases provide a structured way to store, retrieve and also manipulate data
making them integral to modern data management. I will attempt to outline the essential
components of a database and explain how JOINS and subqueries work to pull data
from multiple tables.
Essential Parts of a Database
A database is composed of several key elements that organize data efficiently:
● Tables: The primary structure within a database, consisting of rows and
columns. Each table focuses on a specific type of data, such as customer
information or sales transactions (Elmasri & Navathe, 2020).
● Columns (Attributes): Define the type of data stored in a table, with each
column representing a specific attribute like a customer name or order date
(Connolly & Begg, 2015).
