data warehouse Central repository for all or significant parts of the data that an organisation’s various business systems collect, containing harmonised, highly-structured, quality data integrated from multiple sources. Data warehousing emphasises the capture of data from diverse sources for useful analysis and access, but does not generally start from the point-of-view of the end user who may need access to specialised data marts. There are two approaches to data warehousing: The top-down approach spins off data marts for specific groups of users after the complete data warehouse has been created. The bottom-up approach builds the data marts first and then combines them into a single, all-encompassing data warehouse. https://orcid.org/0000-0002-5214-4466 https://orcid.org/0000-0003-2687-1982 data store
