4.3.1.5 User Interface Detail Data User
Untuk mengakses dan memanipulasi data user, administrator harus masuk ke user interface detail data user dengan cara memilih sub menu User yang
terdapat pada menu Data. Gambar 4.8 merupakan halaman detail data user untuk bagian admnistrator.
Gambar 4.8 Halaman Detail Data User
Halaman ini menampilkan user name, password, dan bagian dari user dalam bentuk form data grid. Pada halaman detail data user ini juga terdapat tombol Add
yang berfungsi untuk menambah data user, tombol Edit yang berfungsi untuk mengupdate data user, tombol Delete yang berfungsi untuk menghapus data user,
tombol Refresh yang berfungsi untuk menampilkan keseluruhan data user yang ada di database, dan tombol Exit yang berfungsi untuk keluar dari program.
Halaman detail data user ini juga dilengkapi dengan dengan fasilitas pencarian PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
user dengan kategori pencarian berdasarkan user name dan bagian. Berikut ini adalah perintah untuk user interface halaman detail data user.
