How can the data entered in a C# form be saved simultaneously to different tables in the database?

[cRen]

I want to create a demo ATM application. There is a form in the registration part that includes fields for name, surname, ID number, and password. I will save this information to the database when I enter them into the textboxes. However, in my database, I have two tables named 'hesap_bilgileri' and 'kullanici_bilgileri'. As shown in the form, I want to save the password entered in the password textbox to the 'hesap_bilgileri' table, and the other information obtained from the other textboxes to the 'kullanici_bilgileri' table at the same time. How can I achieve this?
