4. IMPLEMENTASI SISTEM

Pada bab 4 ini akan dijelaskan tentang segmen-segmen dari aplikasi yang telah dibuat, setting database, implementasi program dan pembahasan lainnya.

4.1. Impelentasi Database

Database yang digunakan dalam pembuatan sistem informasi pada Toko Penjualan Mesin Fotocopy Utama adalah Microsoft SQL Server 2005. Cara membuka Microsoft SQL Server 2005, yaitu dengan menggunakan Management Studio dengan langkah-langkah : Start à Program à Microsoft SQL Server 2005 à SQL Server Management Studio . Untuk membuat database baru pada Microsoft SQL Server 2005, klik kanan untuk memunculkan submeu dan memili menu ’New Database’. Pembuatan database dapat dilihat pada Gambar 4.1.

Gambar 4.1. Pembuatan Database Baru

(2)

4.2. Koneksi Database dengan Microsoft Visual Basic 6.0

Koneksi database dibutuhkan untuk menghubungkan Microsoft SQL Server 2005 dengan Microsoft Visual Basic 6.0. Hal ini dilakukan agar data dari database dapat diakses oleh program. Koneksi database dilakukan dengan melakukan penga turan pada komponen ADODC. Untuk menambahkan komponen ADODC, pilih menu ‘project’ pada menu bar kemudian ‘component’, pilih Microsoft ADO Data Control 6.0, seperti yang dapat dilihat pada Gambar 4.2.

Gambar 4.2. Menambah Komponen ADODC

Masukkan komponen ADODC ke dalam salah satu form dalam Microsoft Visual Basic 6.0. Setelah itu, klik kanan pada komponen ADODC tersebut untuk membuka form properties dari ADODC, seperti dapat dilihat pada Gambar 4.3.

(3)

Gambar 4.3. Properties ADODC

Untuk melakukan koneksi, tekan tombol ‘build ’ dan akan muncul window

‘Data Link Properties’ kemudian pilih ‘SQL Native Client’ kemudian tekan tombol ‘Next’ seperti yang dapat dilihat pada Gambar 4.4.

(4)

Gambar 4.4. Data Link Properties

Masukkan nama server dan database yang akan digunakan. Tekan tombol

‘test connection’ untuk memastikan apakah koneksi sudah berhasil atau tidak, seperti yang dapat dilihat pada Gambar 4.5. Setelah tes koneksi berhasil, maka akan muncul connection string pada property pages, seperti yang dapat dilihat pada Gambar 4.6.

constring = "Provider=SQLNCLI.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Skripsi;Data Source=."

cn.CursorLocation = adUseClient cn.Open constring

4.3. Implementasi Program

Segmen 4.1 adalah segmen yang digunakan untuk login ke dalam program.

Pada segmen ini, sistem dapat membedakan hak akses pemakai program. Dari status yang ada, hak akses dibagi atas dua kategori, yaitu :

o Admin , yang memiliki hak akses penuh terhadap program

o User, yang memiliki hak akses terhadap input order pembelian, pembelian, retur pembelian, laporan pembelian, laporan retur pembelian, order penjualan, penjualan, retur penjualan, laporan penjualan, laporan retur penjualan.

Segmen 4.2. Source Code Login

Set Username = .CreateParameter("Username", adVarChar, adParamInput, 20, "") Set Password = .CreateParameter("Password", adVarChar, adParamInput, 20, "") Set Masuk = .CreateParameter("Masuk", adInteger, adParamOutput, , 0) .Parameters.Append Username

.Parameters.Append Password .Parameters.Append Masuk End With

• Menu Master

Menu master digunakan untuk mengolah data -data yang ada dalam database. Tabel master hanya dapat diakses oleh admin , dimana terdapat empat proses yang meliputi proses insert, update, delete dan search. Seperti yang dapat dilihat pada Tabel 4.1.
