BAB I PENDAHULUAN A. Latar Belakang Berkembangnya teknologi informasi mengubah manusia dalam menyelesaikan semua pekerjannya. Dahulu manusia menyimpan semua informasi dan dokumen menggunakan buku yang disimpan dalam lemari dokumen dan jumlahnya tidak sedikit. Dalam hal ini saya akan membuat Sistem Informasi penjulan hanphone yang dapat membantu mempermudah pendataan penjualan hanphone dalam menyimpan data-data meggunakan komputer (computerized). B. Alasan Pemilihan Masalah Menurut saya aplikasi penjualan handphone ini sangat di buntuhkan di daerah saya yang masih mengunakan system yang manu dalam transaksi bahkan program ini juga di buntuhkan juga di daerah daerah lain. ii

BAB V PENUTUP C. Kesimpulan Dengan demikian dapat disimpulkan bahwa dalam membuat suatu program java dengan menggunakan JDBV ada hal yang paling utama yaitu : koneksi. Untuk dapat terkoneksi dengan database terdapat beberapa langkah yaitu 1. Load driver JDBCb 2. DefinisikanURL database 3. Membuat dan Melakukan Koneksi 4. Membuat obyek statement 5. Mengeksekusi queryf 6. Memproses result Menutup Koneksi dimana table yang tampil pada form adalah model dari class table model dengan parameter konstruktor berupa objek resultset hasil query. Agar bisa terhubung dengan database maka harus melakukan koneksi dengan URL Alamat yang telah didefinisikan dalam string kemudian dijadikan parameter dalam mengkoneksikan pada objek Connection. D. Kesulitan Membuat tampilan view, agar tampilannya lebih besar lagi sehingga data dapat di lihat dengan jelas. 38
