Understanding Relational Database Management Systems (RDBMS)

At the core of many data management systems, relational database management systems (RDBMS) provide a structured way to store and retrieve data. Here’s an introduction to RDBMS and its principles.

What is a Relational Database Management System?

A relational database management system (RDBMS) is a software system for managing relational databases. A relational database is organized into tables, where each table contains columns and rows that represent data attributes and their values, respectively.

Example of a Relational Database Table

Consider an example where a spreadsheet has columns for CUSTOMER_NUMBER, PRODUCT, and QUANTITY_PURCHASED. Each row represents a specific value for each attribute, creating a relational database table:

CUSTOMER_NUMBER PRODUCT QUANTITY_PURCHASED 12345 Vegetable soup 5 45678 Cooking oil 3 42973 Lawn fertilizer 2 81115 Blankets 88 81115 Vegetable soup 33

For a relational database, this table can be part of many others, such as:

A CUSTOMER_MASTER table, containing data like: CUSTOMER_NUMBER CUSTOMER_NAME 12345 Mark Jones 45678 Daniel Michaels 42973 Karen Warner 81115 Susan Robinson A PRODUCT_MASTER table containing data like: PRODUCT UNIT_PRICE Vegetable soup $2.99 Cooking oil $5.99 Lawn fertilizer $10.99 Blankets $79.99

Joining these tables using CUSTOMER_NUMBER as the common attribute can provide more comprehensive information:

For example, customer number 81115 named Susan Robinson not only ordered 88 blankets and 33 cans of vegetable soup but also their unit prices. The power of the relational database becomes evident when you join tables together, allowing you to combine and analyze data from multiple sources efficiently.
