(Record Managements System)

2013RMS (record managements system) merupakan kombinasi antara file system dan database management system yang dapat kita gunakan untuk menyimpan data dalam bentuk baris dan kolom, sama dengan struktur data pada tabel dalam sebuah database. Berikut adalah Menampilkan Nama dengan menggunakan Text Field -> String Item dari Form 1 Kedalam Form 2 . berikut contohnya :1. Flow View Program
Masukan Back Command pada Form1 yang diman command back diperlukan untuk memgembalikan / back ke form sebelumnya . setelah itu click dan drag dari Form 1 ke Form seperti berikut :
Diperlukannya relasi dari OkCommand ( ke Form1 ) yang dimana bila kita menekan tombol OK pada applikasi Mobile tersebut maka dia akan masuk ke Form berikutnya dan sebaliknya BackCommand diperlukan untuk mengembalikan ke Form sebelumnya .
Terdapat 2 Form yang akan digunakan seperti yang diatas dan diisi command untuk OK , BACK , EXIT dari Form tersebut . Setelah itu masuk kedalam Form itu sendiri yang dimana seperti berikut :
2. Screen View Program
Form Input Data
Form Output Data
