For historical reporting and forecasting, you generally want a data warehouse optimized for analytics, not an operational database.
Best choice
Use a cloud data warehouse such as:
- Snowflake
- Google BigQuery
- Amazon Redshift
- Azure Synapse Analytics
These are well-suited for:
- Historical reporting
- Trend analysis
- BI dashboards
- Forecasting/modeling
- Large-scale joins and aggregations
Why a data warehouse?
A data warehouse is designed to:
- Store structured, cleaned, historical data
- Support fast analytical queries
- Keep long time horizons for reporting
- Integrate with BI and forecasting tools
If you mean warehouse architecture
For historical reporting and forecasting, the common pattern is:
- Source systems →
- ETL/ELT pipeline →
- Data warehouse →
- BI / forecasting / ML tools
If you need a practical recommendation
- Small to medium team: BigQuery or Snowflake
- Already on AWS: Redshift
- Already on Azure: Synapse
- Very large, SQL-heavy analytics with flexible scaling: Snowflake is often a strong default
If you want, I can also recommend the best warehouse based on your cloud provider, data size, and budget.
