Connection setup

This guide explains how to connect to your DataHub instance, which is built on Neon PostgreSQL.

Connection parameters

When your DataHub instance is set up, you'll receive these connection parameters via email:

Parameter	Description
Host	The database server address
Port	The connection port (typically 5432)
Database name	Your assigned database name
Username	Your database username
Password	Your secure database password
SSL mode	The SSL connection mode

Data architecture

Your DataHub organizes data in specific schemas:

• raw_business_data - Contains business data tables (users, objects, tasks, etc.)

• raw_telematics_data - Contains telematics data from client devices (GPS tracks, sensor readings)

When querying data, you must specify both the schema (e.g. raw_business_data) and table (e.g. objects) name: SELECT * FROM raw_business_data.objects LIMIT 10;

PostgreSQL compatibility

DataHub is fully compatible with the PostgreSQL protocol. You can connect using:

• Standard PostgreSQL clients (pgAdmin, DBeaver, etc.)

• Programming languages with PostgreSQL drivers (Python, Java, Node.js)

• Business intelligence tools that support PostgreSQL (Tableau, Power BI)

Connection string format

For programmatic access, use the standard PostgreSQL connection string format:

postgresql://username:password@host:port/database?sslmode=ssl_mode

Example with placeholders:

postgresql://client_user:[email protected]:5432/client_123_dwh?sslmode=require

Connection security

Important security considerations:

• SSL encryption - Your data transmission is encrypted according to the specified SSL mode

• Network configuration - Your network must allow outbound connections to the provided host and port

• Credential safety - Your connection credentials are unique to your instance and should be kept secure

Best practices for connections

When working with your DataHub:

• Manage idle connections - Close connections when not in use to free up resources

• Use connection pooling - For applications with frequent database access

• Store credentials securely - Never hardcode credentials in scripts or applications

• Set appropriate timeouts - Configure reasonable connection timeouts for your use case

Connection troubleshooting

If you encounter connection issues:

1. Verify your connection parameters match those in your welcome email

2. Confirm your network allows the connection to the specified host and port

3. Ensure your client supports the required SSL mode
