With dozens of data warehouse systems available, selecting the right one is critical. This guide compares top platforms and provides a decision-making framework.
5 Factors to Consider When Choosing a Data Warehouse System
- Deployment Model
- Cloud (Snowflake, BigQuery): Best for scalability.
- On-Premises (Teradata): Ideal for strict compliance.
- Performance
- Look for columnar storage, indexing, and query optimisation.
- Cost Structure
- Compare storage vs. compute pricing (e.g., Snowflake’s credits vs. Redshift’s nodes).
- Integration Capabilities
- Does it connect to your existing tools (ETL, BI, CRM)?
- Security & Compliance
- Encryption, GDPR/HIPAA support, and access controls.
