Your web application looks great with a smooth UX/UI. But is that enough to keep customers coming back? Not quite.
Building software involves more than just the design. To make sure your app works well, you need to focus on the database. A good database ensures your app is secure, fast, and can handle large amounts of data.
There are many database management systems out there. While having many options is good, it can also make it harder to choose the right one. In this post, we’ll explore 15 of the best databases for web applications to help you make an informed decision.
Popular Database Types for Web Application Developers
When building a web application, the choice of database depends on the specific needs of the project and the ability to handle data storage and management. There are many types of databases for both web and mobile apps, but this article will focus on databases for web applications. Below are four main types of databases that development teams use when creating web apps.
Relational Databases
Relational databases, also called SQL databases, store data in tables with rows and columns. Each table represents a group of related data, like customers, orders, or products. The columns in a table show the details (like names, IDs, or prices), and the rows hold specific entries. For example, one row might be a customer with a name, ID number, and contact information. These databases are useful because developers can easily link tables and pull data from multiple sources. Relational databases are great for keeping data well-organized and ensuring accuracy.
NoSQL Databases (Non-relational Databases)
NoSQL databases work differently from relational ones. Instead of using tables, they store unstructured data in various ways depending on the type of NoSQL database. Some common types include:
- Document databases: Store data as documents (like a JSON file).
- Key-value stores: Save data as pairs, with a key (like an ID) and its value.
- Wide column stores: Use tables, but with more flexible columns.
- Graph databases: Focus on the relationships between pieces of data.
NoSQL databases are great for applications with large, changing data and can easily scale by adding more servers. They work well when the data structure doesn’t stay the same over time.
Object-oriented Databases
Object-oriented databases are designed for programming languages like Java or Python. Instead of storing data in tables, they save it as objects. These objects hold both the data and the actions that can be performed on the data. Each object has unique details like an ID number or specific functions. This type of database works well with object-oriented programming, making it a good fit for web apps that use these languages.
In-Memory Databases
As the name suggests, in-memory databases store data in the memory of a computer rather than on disks or SSDs. This makes them very fast, which is why they’re often used for apps that need real-time data processing, like banking apps. However, they are more expensive than traditional databases because memory is costly. The speed and low-latency performance of in-memory databases make them perfect for applications where every second counts.
Other Types of Databases
Besides the four main types mentioned above, there are a few other databases worth considering for web apps:
- NewSQL databases: Combine the scalability of NoSQL with the reliability of SQL (ACID properties), making them good for high-performance apps.
- Time-series databases: Focus on handling time-stamped data, making them ideal for Internet of Things (IoT) and financial apps.
- Graph databases: Focus on complex relationships between data points and are great for recommendation systems, social networks, and analyzing networks.
Functions of a Database Management System in Business Operations
A key factor that helps modern web apps succeed is the effectiveness of their database management systems. Why is this so important? Below are some of the top functions a good database brings to business operations:
- Data Storage: A database helps businesses organize and store large amounts of data in a structured way.
- Data Retrieval: With tools like SQL queries and reports, businesses can easily get the information they need.
- Data Integrity: A database ensures data is accurate and consistent by using rules for transactions and validation.
- Data Security: With backup and recovery options, businesses can protect sensitive information from unauthorized access.
- Data Scalability: Databases let businesses add more hardware as they grow, making it easy to scale up.
- Data Sharing: By allowing data to be shared across different departments and systems, a database improves collaboration within the company.
