10 Database Examples in Real Life
February 21, 2024Table of Contents
Introduction:
Databases are ubiquitous in modern life, playing a crucial role in storing, managing, and retrieving vast amounts of information. From basic contact lists on our smartphones to complex systems powering the internet, databases are essential tools that impact nearly every aspect of our daily lives.
The purpose of this guide is to showcase examples of database usage across various industries and applications. By highlighting the diverse range of ways in which databases are used, this guide aims to demonstrate their importance and impact on our daily lives. Whether you are a student, a professional, or simply curious about how databases work, this guide will provide you with insights into the world of databases and their practical applications.
What Is a Database?
A database is a structured collection of data that is organized in such a way that it can be easily accessed, managed, and updated. It is designed to efficiently store and retrieve large amounts of information.
To illustrate this concept, consider the analogy of a collection of family recipes stored in a local instance of MongoDB, a popular database management system. In this analogy, each recipe represents a piece of data, such as a recipe name, ingredients, and instructions. MongoDB organizes these recipes in a structured format, allowing users to easily search for and retrieve specific recipes based on their criteria. Just as a database organizes and stores data for easy access, the collection of family recipes in MongoDB is structured and organized for efficient retrieval and management.
How Does a Database Work?
To understand how a database works, let’s use an analogy of a collection of spreadsheets. Each spreadsheet represents a table in the database, and the cells within the spreadsheet contain the data. These tables are interconnected through relational links, similar to how data in one table can be related to data in another.
For example, consider a bookstore database with three tables: Customer, Books, and Sales.
- Customer Table:
- Columns: CustomerID, Name, Email, Phone
- Rows: Each row represents a different customer.
- Books Table:
- Columns: BookID, Title, Author, Price
- Rows: Each row represents a different book.
- Sales Table:
- Columns: SaleID, CustomerID, BookID, SaleDate
- Rows: Each row represents a sale transaction, linking a customer to a book they purchased.
When a new customer makes a purchase, the database system updates the Sales table by adding a new row with the customer’s ID, the book’s ID, and the sale date. This update is done automatically by the database management system (DBMS) to ensure data integrity and consistency.
Similarly, if a customer updates their information (e.g., changes their email address), the change is made in the Customer table. Since the CustomerID is linked to the Sales table, this change can automatically propagate to the Sales table to reflect the updated customer information for all past sales.
In this way, databases work by storing data in tables and managing the relationships between them. The DBMS handles queries, updates, and other operations to ensure that data is stored efficiently and can be accessed quickly when needed.
