melakukan suatu permintaan data atau layanan ke server sedangkan server ialah,
sistem atau proses yang menyediakan data atau layanan yang diminta olehclient.<br />
Client-Server adalah pembagian kerja antara server dan client yg mengakses
server dalam suatu jaringan. Jadi arsitektur client-server adalah desain sebuah
aplikasi terdiri dari client dan server yang saling berkomunikasi ketika
mengakses server dalam suatu jaringan.</span></div>

Dalam konteks basis data, client mengatur interface berfungsi sebagai
workstation tempat menjalankan aplikasi basis data. Client menerima permintaan
pemakai, memeriksa sintaks dan generate kebutuhan basis data dalam SQL atau
bahasa yang lain. Kemudian meneruskan pesan ke server, menunggu response dan
bentuk response untuk pemakai akhir. Server menerima dan memproses permintaan
basis data kemudian mengembalikan hasil ke client.</span></div>

Pada arsitektur ini semua pemrosesan dilakukan pada mainframe. Kode aplikasi,
data dan semua komponen sistem ditempatkan dan dijalankan pada host. Walaupun
computer client dipakai untuk mengakses mainframe, tidak ada pemrosesan yang
terjadi pada mesin ini, dan karena mereka “dump- client” atau “dump-terminal”.
Tipe model ini, dimana semua pemrosesan terjadi secara terpusat, dikenal
sebagai berbasis-host. Sekilas dapat dilihat kesalahan pada model ini. Ada dua
masalah pada komputasi berbasis host: Pertama, semua pemrosesan terjadi pada
sebuah mesin tunggal, sehingga semakin banyak user yang mengakses host, semakin
kewalahan jadinya. Jika sebuah perusahaan memiliki beberapa kantor pusat, user
yang dapat mengakses mainframe adalah yang berlokasi pada tempat itu,
membiarkan kantor lain tanpa akses ke aplikasi yang ada.</span></div>

mainframe. Namun keterbatasan yang dikenakan pada user mainframe dan jaringan
telah mulai dihapus.</span></div>

Arsitektur Three Tier merupakan inovasi dari arsitektur Client Server. Pada
arsitektur Three Tier ini terdapat Application Server yang berdiri di antara
Client dan Database Server. Contoh dari Application server adalah IIS,
WebSphere, dan sebagainya.</span></div>
<div class="MsoNormal" style="line-height: normal; mso-margin-bottom-alt: auto; mso-margin-top-alt: auto; text-align: justify;">
<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt; mso-fareast-font-family: "Times New Roman"; mso-fareast-language: IN;">Application Server umumnya berupa business process
layer, dimana bisa didevelop menggunakan PHP, ASP.Net, maupun Java. Sehingga
kita menempatkan beberapa business logic kita pada tier tersebut. Arsitektur
Three Tier ini banyak sekali diimplementasikan dengan menggunakan Web
Application. Karena dengan menggunakan Web Application, Client Side (Komputer
Client) hanya akan melakukan instalasi Web Browser. Dan saat komputer client
melakukan inputan data, maka data tersebut dikirimkan ke Application Server dan
diolah berdasarkan business process-nya. Selanjutnya Application Server akan
melakukan komunikasi dengan database server.</span></div>
<div class="MsoNormal" style="line-height: normal; mso-margin-bottom-alt: auto; mso-margin-top-alt: auto; text-align: justify;">
<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt; mso-fareast-font-family: "Times New Roman"; mso-fareast-language: IN;">Biasanya, implementasi arsitektur Three Tier
terkendala dengan network bandwidth. Karena aplikasinya berbasiskan web, maka Application
Server selalu mengirimkan Web Application-nya ke computer Client. Jika kita
memiliki banyak sekali client, maka bandwidth yang harus disiapkan akan cukup
besar, Sedangkan network bandwidth biasanya memiliki limitasi. Oleh karena itu
biasanya, untuk mengatasi masalah ini, Application Server ditempatkan pada sisi
client dan hanya mengirimkan data ke dalam database server. Konsep model
three-tier adalah model yang membagi fungsionalitas ke dalam lapisan-lapisan,
aplikasiaplikasi mendapatkan skalabilitas, keterbaharuan, dan keamanan.</span></div>

Arsitektur Multi Tier adalah suatu metode yang sangat mirip dengan Three Tier.
Bedanya, pada Multi Tier akan diperjelas bagian UI (User Interface) dan Data
Processing. Yang membedakan arsitektur ini adalah dengan adanya Business Logic
Server. Database Server dan Bussines Logic Server merupakan bagian dari Data
Processing, sedangkan Application Server dan Client/Terminal merupakan bagian
dari UI. Business Logic Server biasanya masih menggunakan bahasa pemrograman
terdahulu, seperti COBOL. Karena sampai saat ini, bahasa pemrograman tersebut
masih sangat mumpuni sebagai business process.</span></div>

tier yang diperluas dalam model fisik yang terdistribusi. Application server
dapat mengakses Application server yang lain untuk mendapat data dari Data
server dan mensuplai servis ke client Application.</span></div>

Local Area Network (LAN) adalah sejumlah komputer yang saling dihubungkan
bersama di dalam satu areal tertentu yang tidak begitu luas, seperti di dalam
satu kantor atau gedung. Secara garis besar terdapat dua tipe jaringan atau
LAN, yaitu jaringan Peer to Peer dan jaringan Client-Server. Pada jaringan peer
to peer, setiap komputer yang terhubung ke jaringan dapat bertindak baik
sebagai workstation maupun server. Sedangkan pada jaringan Client-Server, hanya
satu komputer yang bertugas sebagai server dan komputer lain berperan sebagai
workstation.</span></div>
