Abstract: The use of database in clinical research is an innovation. Clinical database inf ormation provides a way to evaluate and improve the overall process and results of the broader system of patient care. Exploring questions that arise from this data can identify system issues, which are invisible to individual practitioners or specialties using other traditional review methods. Compared with the first generation database designed in Access by National Conge nital Heart Surgery Database Committee, our database is more complex with full p otential, which can totally meet the needs of clinicians and researchers in the study of congenital heart defects and can provide remote information data sharin g digital platform. Since congenital heart disease surgery is arapidly developin g subject, our database provides assistant tables, with which the new diagnosis, operation and medicine can be combined into the system.

Key words: congenital heart disease, specialized database, medical information digitalization
