. Introduction

neo4j There is a powerful database that works with attached data. Unlike traditional databases that use tables, NEO4J uses nodes and relationships. This setup makes the data easier to detect complex links. Neo4J is known for projects like social networks, recommendations systems, and network analysis.

This article will show you how to install and configure the Neo4J. We will start with your basic things before installing. Next, we will examine various ways to install the Neo4J, such as the Neo4j Desktop or the Discovery. Finally, we will guide you in the first stages of the use of Neo4j.

2. Play the neo4j in the container:

docker run \
    --name neo4j \
    -p7474:7474 -p7687:7687 \
    -d \
    -e NEO4J_AUTH=neo4j/password \
    neo4j

3. Access Neo4j:

Open your browser and go Then login as username and password with the Neo4J that you have set in the Dokar Command.

. Early Setup and Configure

After installation, some initial setting must be ensured that the Neo4J is safe and will configure your features.

1. Set up a strong password: If you don’t have before, change the default neo4j password by logging into the neo4j browser
2. Edit the Configure File: Open neo4j.conf In the Neo4J Installation Directory and adjust the settings as needed
3. Enable/Disable plugin: At the Neo4J Desktop, you can enable plugin such as APOC (Great procedures on the Capital) and graph data science.

. To access the neo4j browser

The Neo4J Browser is an interactive console that facilitates you to run a cypress questions and imagine data as a graph. To access this:

1. Open your browser: Barley
2. Login: Enter the username and password
3. Run the questions: Use Basic Cyper Commands such as matches, create, and return to data from data and start searching
4. Sorting and Settings: Adjust display options, inquiry limits, and other settings to give your experience personal

. Basic Cyper Commands

The immediate introduction of some basic cypress commands to start with Neo4j is:

Make nodes: Make a person representing a person

CREATE (n:Person {name: 'Alice', age: 30})

Create a relationship: Connect two nodes with a relationship

MATCH (a:Person {name: 'Alice'}), (b:Person {name: 'Bob'})
CREATE (a)-(:FRIENDS_WITH)->(b)

Recover nodes: Recover all the nodes with the label person

MATCH (n:Person) RETURN n

Update Properties: Update the property on the node

MATCH (n:Person {name: 'Alice'})
SET n.age = 31

Delete nodes and relationships: Delete a node and all its relationships

MATCH (n:Person {name: 'Alice'})
DETACH DELETE n

. Next steps

Now, you are ready to start your first graph projects. There are some easy ways to continue to learn:

• Experience with Neo4J plugin: APOC and graph data increases plug -in functionality such as science, making it easier to conduct complex operations
• Discover the Cyper: Learn more about Cyper’s powerful inquiry abilities through Neo4j’s Cyper Documents
• Create real world applications: Consider the issues of use such as Neo4j’s Recommendation System, Network Analysis, and fraudulent detection

. Conclusion

Neo4J is a strong graph database for connected data. Its data model and the language of Cyper Question make it easier to handle complex relationships. Neo4J is perfect for social networks, recommendations, and network analysis. With the NEO4J setup and basic cypress skills, you are ready to find a graph database and create data -driven applications.
