Tugas TIK
SISTEM INFORMASI
PENGERTIAN
Sistem informai adalah sekumulan hardware, software, brainware, prosedur atau aturan yang diorganisasikan secara integral untuk mengolah data menjadi informasi yang bermanfaat guna memecahkan dan pengambilan keputusan.
Komponen Sistem Informasi
Perangkat Keras (Hardware)
Perangkat lunak (Software) atau program
Prosedur
Orang
Basis Data (Database)
Jaringan komputer dan komunikasi data
Siklus hidup pengembangan Sistem Infrmasi
SLDC
Software Development Life Cycle
Adalah suatu proses pembuatan software yang meliputi :
Scoping – Requirement Collection & Analysis – Prototyping – Designing – Coding – Testing – Implementing – Maintaining.
3 Macam Arsitektur
1. Arsiektur tersentralisasi
2. Arsitektur terdistribusi
3. Arsitektur client/Srver
