When you look for a Database DB-Engine, it can feel confusing. There are so many choices out there. DB-Engines helps by ranking databases every month. They check how much people talk about each one online. They look at websites, forums, and job boards. They also use Google Trends and look at work profiles. This helps you see which databases are popular in 2025 and why they matter.
Relational Databases
Relational databases have been used for many years. You use them to keep data in tables. This keeps your data neat and organized. These databases follow rules to keep your data safe and correct. They use the ACID model, so your data is always reliable. If you want simple and organized data, pick a relational Database DB-Engine.
Here’s a quick way to see how relational and NoSQL databases are different:
| Category | Relational database | Non-relational database |
|---|---|---|
| Data model | Tabular. | Key-value, document, or graph. |
| Data type | Structured. | Structured, semi-structured, and unstructured. |
| Data integrity | High with full ACID compliance. | Eventual consistency model. |
| Performance | Improved by adding more resources to the server. | Improved by adding more server nodes. |
| Scaling | Horizontal scaling requires extra strategies. | Horizontal scaling is straightforward. |
Tip: Use relational databases when you need strong data rules and clear links between your data.
NoSQL Databases
NoSQL databases work differently. You use them when your data does not fit in tables. They let you store many types of information. This can be documents, graphs, or key-value pairs. NoSQL uses the BASE model. This means they focus on being available and flexible. The data may not always be up-to-date, but it is easy to use.
Here are the main types of NoSQL databases you might see in 2025:
Key-Value Stores
Wide Column Stores
Document Stores
Graph DBMS
RDF Stores
Native XML DBMS
Content Stores
Search Engines
Better performance for big jobs
Easy sharing of data across many servers
Good scaling and fault tolerance
Flexible data models without a set structure
Simple management
You might choose a NoSQL database if you have lots of data, want to grow fast, or need to work with many types of information.
