Relational vs. Non-Relational Databases

Introduction

Databases are a crucial part of modern-day technology, providing better access to the organization of information and efficient data storage. They vary in size based on the applications they support—from small, user-specific applications to large enterprise databases managing extensive customer data. When discussing databases, it's important to understand the two primary types: Relational vs Non-Relational Databases, each offering different approaches to data management. So, where should you start? Let's take it step by step.

What Are Databases?

A database is simply an organized collection of data that empowers users to store, retrieve, and manipulate data efficiently. Organizations, websites, and applications depend on databases for almost everything between a customer record and a transaction.

Types of Databases

There are two main types of databases:

Relational Databases (SQL) – Organized in structured tables with predefined relationships.

Non-Relational Databases (NoSQL) – More flexible, allowing data to be stored in various formats like documents, graphs, or key-value pairs.

Let's go through these two database types thoroughly now.

Relational Data Base:

A relational database is one that is structured in the sense that the data is stored in tables in the manner of a spreadsheet. Each table includes rows (or records) and columns (or attributes). Relationships between tables are then created and maintained by the keys.

Examples of Relational Databases:

MySQL .

PostgreSQL .

Oracle .

Microsoft SQL Server .

What is a Non-Relational Database?

Non-relational database simply means that it does not use structured tables. Instead, it stores data in formats such as documents, key-value pairs, graphs, or wide-column stores, making it adaptable to certain use cases.

Some Examples of Non-Relational Databases are:

MongoDB (Document-based)

Redis (Key-value)

Cassandra (Wide-column)

Neo4j (Graph-based)

Key Differences Between Relational and Non-relational Databases.

1. Data Structure

Relational: Employs a rigid schema (tables, rows, columns).

Non-Relational: Schema-less, allowing flexible data storage.

2. Scalability

Relational: Scales vertically (adding more power to a single server).

Non-Relational: Scales horizontally (adding more servers).

3. Performance and Speed

Relational: Fast for complex queries and transactions.

Non-Relational: Fast for large-scale, distributed data.

4. Flexibility

Relational: Perfectly suitable for structured data with clear relationships.

Non-Relational: Best suited for unstructured or semi-structured data.

5. Complex Queries and Transactions

Relational: It can support ACID (Atomicity, Consistency, Isolation, and Durability).

Non-Relational: Some NoSQL databases can sacrifice consistency for speed.

Instances where a relational database should be put to use:

Financial systems Medical records E-commerce transactions Applications with strong data integrity When to Use a Non-Relational Database: Big data applications IoT and real-time analytics Social media platforms Content management systems

Selecting the Most Appropriate Database for Your Project

Check the following points when considering relational or non-relational databases:

✔ Data structure requirement

✔ Scalability requirement

✔ Performance expectation

✔ Complexity of query

Trend of future in databases

The future of the database tells a lot about the multi-model databases that shall host data in both a relational and non-relational manner. There is also a lean towards AI-enabled databases that are to improve efficiency and automation in management.

Conclusion

The advantages of both relational and non-relational databases are different; they are relative to specific conditions. Generally, if the requirements involve structured data within a high-class consistency level, then go for relational databases. However, if needs involve scalability and flexibility, then a non-relational kind would be the wiser option.

SQL Fundamentals #1: SQL Data Definition

Last year in college , I had the opportunity to dive deep into SQL. The course was made even more exciting by an amazing instructor . Fast forward to today, and I regularly use SQL in my backend development work with PHP. Today, I felt the need to refresh my SQL knowledge a bit, and that's why I've put together three posts aimed at helping beginners grasp the fundamentals of SQL.

Understanding Relational Databases

Let's Begin with the Basics: What Is a Database?

Simply put, a database is like a digital warehouse where you store large amounts of data. When you work on projects that involve data, you need a place to keep that data organized and accessible, and that's where databases come into play.

Exploring Different Types of Databases

When it comes to databases, there are two primary types to consider: relational and non-relational.

Relational Databases: Structured Like Tables

Think of a relational database as a collection of neatly organized tables, somewhat like rows and columns in an Excel spreadsheet. Each table represents a specific type of information, and these tables are interconnected through shared attributes. It's similar to a well-organized library catalog where you can find books by author, title, or genre.

Key Points:

Tables with rows and columns.

Data is neatly structured, much like a library catalog.

You use a structured query language (SQL) to interact with it.

Ideal for handling structured data with complex relationships.

Non-Relational Databases: Flexibility in Containers

Now, imagine a non-relational database as a collection of flexible containers, more like bins or boxes. Each container holds data, but they don't have to adhere to a fixed format. It's like managing a diverse collection of items in various boxes without strict rules. This flexibility is incredibly useful when dealing with unstructured or rapidly changing data, like social media posts or sensor readings.

Key Points:

Data can be stored in diverse formats.

There's no rigid structure; adaptability is the name of the game.

Non-relational databases (often called NoSQL databases) are commonly used.

Ideal for handling unstructured or dynamic data.

Now, Let's Dive into SQL:

SQL is a :

Data Definition language ( what todays post is all about )

Data Manipulation language

Data Query language

Task: Building and Interacting with a Bookstore Database

Setting Up the Database

Our first step in creating a bookstore database is to establish it. You can achieve this with a straightforward SQL command:

CREATE DATABASE bookstoreDB;

SQL Data Definition

As the name suggests, this step is all about defining your tables. By the end of this phase, your database and the tables within it are created and ready for action.

1 - Introducing the 'Books' Table

A bookstore is all about its collection of books, so our 'bookstoreDB' needs a place to store them. We'll call this place the 'books' table. Here's how you create it:

CREATE TABLE books ( -- Don't worry, we'll fill this in soon! );

Now, each book has its own set of unique details, including titles, authors, genres, publication years, and prices. These details will become the columns in our 'books' table, ensuring that every book can be fully described.

Now that we have the plan, let's create our 'books' table with all these attributes:

CREATE TABLE books ( title VARCHAR(40), author VARCHAR(40), genre VARCHAR(40), publishedYear DATE, price INT(10) );

With this structure in place, our bookstore database is ready to house a world of books.

2 - Making Changes to the Table

Sometimes, you might need to modify a table you've created in your database. Whether it's correcting an error during table creation, renaming the table, or adding/removing columns, these changes are made using the 'ALTER TABLE' command.

For instance, if you want to rename your 'books' table:

ALTER TABLE books RENAME TO books_table;

If you want to add a new column:

ALTER TABLE books ADD COLUMN description VARCHAR(100);

Or, if you need to delete a column:

ALTER TABLE books DROP COLUMN title;

3 - Dropping the Table

Finally, if you ever want to remove a table you've created in your database, you can do so using the 'DROP TABLE' command:

DROP TABLE books;

To keep this post concise, our next post will delve into the second step, which involves data manipulation. Once our bookstore database is up and running with its tables, we'll explore how to modify and enrich it with new information and data. Stay tuned ...
