-Graphs are everywhere. When hearing the word graph, many people think of bar charts or line charts, because sometimes we call them graphs, which show the connections between two or more data systems.

 ## What is a graph database
 
-A graph database, such as Nebula Graph, is a database that specializes in storing vast graph networks and retrieving information from them. It efficiently stores data as vertices (nodes) and edges (relationships) in labeled property graphs. Properties can be attached to both vertices and edges. Each vertex can have one or multiple tags (labels).

 ![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.
 
-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
+## Advantages of NebulaGraph
 
 ### 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).

 ### Intelligent question-answer system
 
-Natural languages can be transformed into knowledge graphs and stored in Nebula Graph. A question organized in a natural language can be resolved by a semantic parser in an intelligent question-answer system and re-organized. Then, possible answers to the question can be retrieved from the knowledge graph and provided to the one who asked the question.

 ### 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.
