Towards development of health Data Warehouse: Bangladesh perspective

Health informatics is one of the top most focuses of researchers now a days. Availability of timely and accurate data is essential for informed medical decision making. Health care organizations face a common problem with large amount of data they have in numerous systems. Such systems are unstructured and unorganized, requires computational time for data integration. Researchers, medical practitioners, health care providers and patients will not be able to utilize the knowledge stored in different repositories unless synthesize the information from disparate sources. This problem can be solved by Data warehousing. Data warehousing techniques share a common set of tasks, include requirements analysis, data design, architectural design, implementation and deployment. Developing Clinical data warehouse is complex and time consuming but is essential to deliver quality patient care. Data integration tasks of medical data store are much challenging when designing clinical data warehouse architecture. This research identifies prospects and complexities of Health data warehousing and Mining in Bangladesh perspective and proposes a data-warehousing model suitable for integrating data from different health care sources.
