membuat aplikasi sederhana Data barang di netbin

MEMBUAT PROGRAM APLIKASI DATA BARANG

1.       Deskripsi aplikasi

Di dalam apllikasi menjalaskan bagaimana kita menjalakan aplikasi yang telah di buat oleh pengguna dan memudahkan utuk kita untuk memanage barang yang ada, dan juga disini aplikasi sudah terhubung ke database dan sangat enak unutuk pergunakan.

2.       Flowchart

3.       Screenshot code

 

a.       Di atas dijelaskan  bagaimana kita menjelaskan infut barang di databases

 

b.      Dan disini adalah bagaimana kita sudah membuat databases

4.       Souce code
