SISTEM INFORMASI MANAJEMEN
Pengertian
Sistem informasi adalah sekumpulan hardware,software,brainware,prosedur dan atau aturan yang diorganisirkan secara integral untuk mengolah data menjadi informasi yang bermanfaat guna memecahkan masalah dan pengambilan keputusan.
Komponen Sistem Informasi :
- Perangkat keras (hardware)
- Perangkat lunak (software) atau program
- Prosedur
- Orang
- Basis data (database)
- Jaringan komputer dan komunikasi data
3 MACAM ARSITEKTUR
1. Arsitektur Tersentralisasi
Suatu proses pelayanan informasi yang dikelola secara terpusat
2. Arsitektur Terdistribusi
Suatu proses pelayanan informasi yang dikelola secara tersebar
3. Arsitektur Client <-> Server
Suatu proses pelayanan informasi yang database utama dikelola Server sedangkan proses analisis lebih lanjut dilakukan oleh Client
