This article discusses how important data warehousing is for developing organisations. data warehousing is a great asset for organisations to plan and prioritise their interventions for helping victims of war remnants. This article shows how information should be of high quality and accounted for. Information extracted from data warehouses can be used to show the impact of intervention on beneficiaries. It also enables more effective stakeholder interaction. Data warehousing assists organisations to gain a competitive advantage by providing good service to beneficiaries and, will, consequently, help organisations to attract donor funds. The example given from Iraq shows how Iraqi Health and Social Care Organisations used a data warehouse to identify needs, plan projects and raise funds for survivors of explosive remnants of war. This concept can be used by other development and aid organisations operating in countries affected by explosive remnants of war and health related development fields.
