A health informatics transformation model based on intelligent cloud computing – exemplified by type 2 diabetes mellitus with related cardiovascular diseases

•This study established a health informatics transformation model (HITM) with the cloud-computing technique.•The PL/SQL modules were created in the database for preprocessing and training the analytical data.•The results performed run-time efficiency of the platform and the feature prediction reached an accuracy of 90%.•The HITM can be customized for the actual clinical database with proper machine learning in cloud computing.•The feedback of computing can be expected to be a reference for risk assessment in health promotion.
