Problems with dicom database creation

I searched a lot of information on the Internet and roughly summarized that 5 tables are currently needed, 1. Patient (patientID is the primary key) 2. Examination (study instance UID is the primary key) 3. Sequence (series instance UID is the primary key) 4. Image instance UID as primary key) 5. Put the primary key of each table into this table to facilitate association, and the most important thing for dicom files is to save them on the server. Is there anything else you need to add?
