Design And Implementation of a National Health Data Warehouse For The Healthcare System In Bangladesh

Information is the most valuable asset in the world. Gathering information from certain sources in an organized manner will allow us to conduct a thorough study of the whole system. In this paper, we created Bangladesh's National Health Data Warehouse. The primary goal of this research work is to collect data from specific medical sources and to conduct a thorough examination of the whole health system utilizing Big Data analysis. The key data scopes will be gathered from a variety of hospitals, clinics, government health care centers, and other health institutions. Then save them in Big Data format when they have been collected. The National Health Data Warehouse (NHDW) will allow us to make more accurate observations throughout the whole health system of Bangladesh. With such a large collection of information, we will be able to limit data analysis and decision-making. Based on the system's analytical challenges, we will confront certain fundamental obstacles during data collection. We will go through each one individually.
