A.Pengenalan Database, DBMS dan RDBMS

Basis data (atau database) adalah kumpulan informasi yang disimpan di dalam komputer secara sistematik sehingga dapat diperiksa menggunakan suatu program komputer untuk memperoleh informasi dari basis data tersebut (http://id.wikipedia.org/wiki/Database). Database digunakan  untuk menyimpan informasi atau data yang terintegrasi dengan baik di dalam komputer. Untuk mengelola database diperlukan suatu perangkat lunak yang disebut DBMS (Database Management System).

DBMS (Database Management System) merupakan suatu sistem perangkat lunak yang memungkinkan user (pengguna) untuk membuat, memelihara, mengontrol, dan mengakses database secara praktis dan efisien. Dengan DBMS, user akan lebih mudah mengontrol dan memanipulasi data yang ada. Sedangkan RDBMS atau Relationship Database Management System merupakan salah satu jenis DBMS yang mendukung adanya relationship atau hubungan antar tabel. Di samping RDBMS, terdapat jenis DBMS lain, misalnya Hierarchy DBMS, Object Oriented DBMS, dsb.

Beberapa software atau perangkat lunak DBMS yang sering digunakan dalam aplikasi program antara lain :

B.Beberapa Istilah Database 

clip_image005 Table 
Sebuah tabel merupakan kumpulan data (nilai) yang diorganisasikan ke dalam baris (record) dan kolom (field). Masing-masing kolom memiliki nama yang spesifik dan unik.
clip_image001  Field 
Field merupakan kolom dari sebuah table. Field memiliki ukuran type data tertentu yang menentukan bagaimana data nantinya tersimpan.
clip_image001[1]  Record 
Field merupakan sebuah kumpulan nilai yang saling terkait.
clip_image001[2]  Key 
Key merupakan suatu field yang dapat dijadikan kunci dalam operasi tabel. Dalam konsep database, key memiliki banyak jenis diantaranya Primary Key, Foreign Key, Composite Key, dll.
