Answers are AI-generated from CASRAI’s own published pages and can be wrong, so check the linked sources before relying on one; your question is logged without personal data — never sold, never used to train a third-party model — to show us what CASRAI is missing, so please do not type personal or confidential details. How we use this

Examples

Worked examples

  • Is an instance

    A university research-analytics data warehouse aggregating CRIS publications, HR employment, and finance grants for institutional dashboards.

  • Is an instance

    A national funder's data warehouse of award spend and outputs.

Counter-examples

Looks similar, but isn't

  • Not an instance

    A raw S3 bucket of files is a data lake, not a data warehouse.

  • Not an instance

    An OLTP transactional database is not a data warehouse.

Editorial commentary

Data warehousing dates to the 1980s and 1990s (Inmon, Kimball) and remains the dominant pattern for organisational reporting. In research-information contexts, a data warehouse may aggregate CRIS, HR, finance, and student-system data to support institutional analytics; OECD and national funders maintain warehouses of research-spend data. Modern cloud data warehouses (Snowflake, BigQuery, Redshift, Synapse) blur the lake/warehouse distinction by combining cheap storage with on-demand SQL compute.
