Data warehouse integration consolidates together information from several sources into one central database. Any department within healthcare facilities may access the data warehouse, and the information can be quickly organised into tables or spreadsheets for analytical and research needs. Additionally, it can link with phone systems and other corporate tools, giving instant access to information without having to move between systems and speeding up processes. Potential mistakes, such as incorrectly written patient information, are also prevented through the checks and balances mechanism of the data warehouse connection.
