The 5 Best Databases for Web Apps in 2023: How to Make the Right Choice

What does a database mean? 

A database is a structured collection of data or a type of data storage that allows users to manage, store, and retrieve information efficiently. Databases are essential for any software product because they ensure data integrity, reliability, and accessibility. A database consists of the following components: 

  •  Hardware: physical equipment, such as servers, and network infrastructure, for hosting and supporting databases;
  •  Software: a database management system (DBMS); 
  • Data:  information that is organized into rows, columns, or tables; 
  • Procedures: processes and rules for managing and manipulating stored information; 
  •  Database access language: a language that lets users add, modify, or extract data from databases.  

The main types of databases

In order to choose between the wide range of solutions available, it is important to consider their main types and their differences. There are two types, depending on the way the information is stored.  

Relational databases

A relation (SQL) database organizes and stores data in tables that are composed of rows and columns. Each table carries a key that makes the data unique from others. These solutions are designed to maintain data integrity and offer flexibility in querying and manipulating data using Structured Query Language (SQL).

Non-relational database

A non-relational (NoSQL) databasediffers from traditional relational ones in a way it organizes and stores the data. These databases are designed to handle large volumes of unstructured, semi-structured, and complex data in a more flexible and scalable manner than traditional databases. NoSQL databases do not rely on the tabular structures. Instead, they use different data models, such as document-based, key-value, wide-column stores, and graph databases.  

 A brief overview of the key differences between both: 

ScalabilityVertical (scale-up with a larger server)Horizontal (scale-out across multiple servers)
StructureTable-basedIs a document, key-value, graph, or wide-column stores

Why is the right database important for web apps? 

As applications operate and gather more data, the need for its structured storage and efficient management becomes paramount. A database takes over this responsibility. It provides a structured and organized framework for the storage, retrieval, and manipulation of a large set of information, ensuring its accessibility and integrity. Consequently, databases help manage, process, and derive insights from this information for various application functions and user needs.  

Choosing an appropriate solution significantly impacts an application’s overall success, influencing its efficiency, responsiveness, and long-term performance. Now, let’s delve into the factors to consider in order to make the right choice. 

Factors to consider when choosing a database web application 

Each project has different requirements for a database. However, there are basic factors that will help you determine if a database will fit well with you or not. These factors include:  

Data model 

As different databases are designed to handle different data types, you must determine which type of data structure suits your business best. For example, if your data is structured and requires complex queries, an SQL database is the most suitable choice. If you deal with unstructured or semi-structured data, a document-oriented database is a better choice.

For example, you want to build a social media platform that stores and processes large amounts of user-generated content, such as photos and videos. In that case, it is best to use NoSQL databases, MongoDB, or Cassandra. They are capable of handling large amounts of unstructured data and can quickly scale upon the need. 


To ensure your web applications database will handle growing data and user traffic over time without damaging performance, scalability is an essential factor to consider upfront. You may consider:  

  • Horizontal scaling: it allows users to seamlessly add more servers or nodes to a database cluster to manage growing data volumes and user needs. It is often more cost-effective than vertical scaling, which requires upgrading server hardware; 
  • Sharding: databases with sharding allow users to distribute data across multiple servers or nodes, resulting in both improved performance and scalability;
  • Replication: databases with replication allow creating data duplicates across multiple servers or nodes. 

It is essential to choose a database that can quickly scale to meet your project needs, whether you need to add additional servers or replicate your data. Selecting a solution that can scale horizontally and vertically may be a good idea if you want to scale rapidly. Databases such as NoSQL and NewSQL are often more flexible in this regard.


Performance is crucial in determining how responsive and efficient your application will be. You should evaluate a database with several key performance aspects in mind.

Firstly, determine the database speed. A fast-performing database ensures swift data retrieval and storage, which is crucial for a smooth user experience. Secondly, consider the ability to handle complex queries. Many web apps require efficient processing of intricate data requests, and the database capabilities in this regard are significant. 

Moreover, think about how well a database will perform with large datasets. Some apps deal with substantial amounts of data, and a database must manage this effectively without causing performance issues. Consider different features that a database may include, such as indexing, that can enhance data retrieval speed by optimizing search operations. 


As you evaluate potential costs, it is essential to keep in mind the following points:

  • License fees: many databases require a license fee, which depends on the size and scope of your project;
  • Hosting costs: you need to consider the cost of hosting a cloud solution such as Amazon RDS or Google Cloud SQL, which can vary greatly depending on the project size and complexity;
  • Maintenance costs: as many databases are open source, they are available free of charge, but you may need to pay for their support or maintenance.

Startups and small businesses may find open-source solutions like MySQL or PostgreSQL more attractive because they provide powerful functionality at a low cost. Commercial databases like Oracle may offer extensive features and support, but they may come at a higher price.

Thus, to ensure your solution aligns with your budget, it is crucial to take both the initial and ongoing costs of a database into account. 

Integration with other technologies

When choosing a database for your project, it’s essential to consider how well it integrates with other technologies you’ll use. For example, if you’re building a web app, you’ll want to choose a database that integrates well with the web framework that you’re using (such as Django). This will make it easier to connect a database to your app and speed up the development process. 

Besides, it is equally important to assess how a selected database will integrate with other tools and technologies in your tech stack. This may include evaluating its integration with caching systems, data visualization tools, and analytics platforms. Moreover, consider your web app’s future requirements. Will you need to support real-time data processing or deploy machine learning? Choose a database that can evolve with your future demands as well.

Community support 

Consider the level of support and documentation offered by a database. A strong community provides access to various resources, including documentation, forums, tutorials, and plugins and extensions. As a result, the database will probably receive frequent updates, bug fixes, and new features.
