![What is a graph database](https://docs-cdn.nebula-graph.com.cn/docs-2.0/1.introduction/what-is-a-graph-database.png "What is a graph database")

Graph databases are well suited for storing most kinds of data models abstracted from reality. Things are connected in almost all fields in the world. Modeling systems like relational databases extract the relationships between entities and squeeze them into table columns alone, with their types and properties stored in other columns or even other tables. This makes the data management time-consuming and cost-ineffective.
Graph databases are well suited for storing most kinds of data models abstracted from reality. Things are connected in almost all fields in the world. Modeling systems like relational databases extract the relationships between entities and squeeze them into table columns alone, with their types and properties stored in other columns or even other tables. This makes data management time-consuming and cost-ineffective.

Nebula Graph, as a typical native graph database, allows you to store the rich relationships as edges with edge types and properties directly attached to them.

## Advantages of Nebula Graph

### Open-source
### Open source

Nebula Graph is open under the Apache 2.0. More and more people such as database developers, data scientists, security experts, and algorithm engineers are participating in the designing and development of Nebula Graph. To join the opening of source code and ideas, surf the [Nebula Graph GitHub page](https://github.com/vesoft-inc/nebula-graph).

### Outstanding performance

Written in C++ and born for graph, Nebula Graph handles graph queries in milliseconds. Among most databases, Nebula Graph shows superior performance in providing graph data services. The larger the data size, the greater the superiority of Nebula Graph. For more information, see [Nebula Graph benchmarking](https://discuss.nebula-graph.io/t/nebula-graph-1-0-benchmark-report/581).

### High scalability

Nebula Graph is designed in a shared-nothing architecture and supports scaling in and out without interrupting the database service.

### Developer friendly

Nebula Graph supports clients in popular programming languages like Java, Python, C++, and Go, and more are being developed. For more information, see Nebula Graph [clients](../20.appendix/6.eco-tool-version.md).

### Social networking

Information on people and their relationships are typical graph data. Nebula Graph can easily handle the social networking information of billions of people and trillions of relationships, and provide lightning-fast queries for friend recommendations and job promotions in the case of massive concurrency.
