Bab.1

Pendahuluan.Latar Belakang.Pada tahun delapan puluhan pemrograman aplikasi komputer dibuat melalui bahasa pemograman seperti COBOL, FORTAN, PL/I, PASCAL (3rd generation language), dBASE, FOXPRO, CLIPPER serta yang lainnya yang mengakses data dalam system sentral. Program terdiri dari atas User-Interface, Bussines Logic dan Data Access yang semuanya dibuat dalam satu program. Pola ini berkembang pada apikasi Personal Computer (PC). Pada perkembangannya system membutuhkan akses data bersama (shared resource) melalui teknologi jaringan, sumber daya seperti disk dan file dapat diakses bersama. Model komputerisasi ini dikenal dengan nama Disk Server atau File Server. BASIC (Beginners All Purposes Symbolic Intruction Code) adalah bahasa pemrograman yang awalnya banyak digunakan pada aplikasi yang bersifat hobi dilingkungan Komputer Micro. Basic memberikan kemudahan kepada programmer untuk membuat aplikasi dalam waktu yang relative singkat dengan struktur program yang sederhana. Berbasis GUI (Graphical User Interface), interaksi antara pengguna aplikasi dengan aplikasi dilakukan melalui antarmuka graphic. Berbasis OOP (Objek Oriented Programming), merupakan metode pemrograman modern yang sering disebut pemrograman generasi ke-empat (GL4) yang lebih banyak menguntungkan para programmer dalam membuat aplikasi . Salah satu keuntungan OOP adalah Reusability (kemampuan untuk digunakan kembali), yaitu komponen-komponen yang sudah pernah dibuat, baik dibuat sendiri maupun dibuat oleh pihak lain dapat diintegrasikan kembali dalam aplikasi yang baru.

Bab. 2

Perancangan Apliakasi Program.

Laporan data tentang penjualan selama ini memang sudah terkomputerisasi dengan baik menggunakan Word processor dan Spread sheet, akan tetapi masih tetap kurang efisien dan fleksibel pada jaman sekarang ini yang semuanya butuh sesuatu yang instan, maka dari itu butuh aplikasi khusus berupa perangkat lunak berbasis data. Aplikasi Program ini di rancang sedemikian rupa sesuai dengan kebutuhan yang di perlukan seperti memasukkan data dari para pegawai, data barang, data harga, dan hasil dari transaksi penjualan. Ada pula hasil report dari aplikasi tersebut untuk memudahkan mengetahui hasil dari Perancangan Aplikasi Program yang telah di buat.

Pada makalah ini diberikan contoh contoh pembuatan tentang Program Aplikasi Penjualan serta berupa codding (kode program) untuk memudahkan kepada para pembaca untuk memahaminya. Serta langkah-langkah dari pembuatan Aplikasi di bawah ini:

Bab.3

Implementasi 1) Spesifikasi H/Wa) Bagaimana cara menginput data Program Aplikasi Penjualan di atas? Yaitu dengan cara mengkoneksikan data inputan database yang berada di Microsoft Access dengan Visual Studio Basic. Net 2005. Cara mengkoneksikannya yaitu : 1) Pilih Connection To Database pada Tools di Menu Bar.

2) Pilih Microsost Access Database File (OLE DB). 3) Cari Database yang telah di buat di Microsoft Access. 4) Lalu Test Connection.
