Metadata for Data Warehousing

  • Prakash M. Nadkarni
Part of the Health Informatics book series (HI)


A data warehouse is kind of database whose architecture (and underlying supporting technology) has been optimized for highly efficient query, at the cost of sacrificing features that support robust interactive inserts, updates and delete actions. The difference between a data warehouse and a data mart (which is also optimized for the same purpose) is partly one of scope. While warehouses are supposed to encompass data across an entire organization, data marts are typically smaller scale (e.g., departmental in scope) though in an ideal situation they would receive data from a warehouse, effectively serving as front-ends to the latter.
