how to store resultant values of edit text and pushbutton of a GUI in a database?

I have created a GUI which accepts name, id and input fingerprint image. edittext1 contains string which is saved as follows,

                    y = get(hObject,'string');
                    handles.edit1 = y;
                    guidata(hObject,handles)

edittext2 accepts id number, which is as follows

                    x = str2num(get(hObject,handles));
                    handles.edit1 = x;
                    guidata(hObject,handles)

a push button which extracts features of fingerprint image generates a binary string is as follows,

                       imshow(I) %I contains the extracted image%
                       B=im2bw(I); %B is the binary matrix of the image.
                       display(B);

Now, i need to store these 3 values in a database using another callback function to access these parameters and write an sql query to store them. I dont know if this is right way to proceed.. can someone please help me in writing code for accessing them and storing them ?
