Dari namanya yaitu SQLite maka kita bisa menebak bahwa SQLite adalah SQL versi Lite yang berarti kecil dan kompak. Memang benar SQLlite adalah database SQL yang kecil dan praktis. SQLite hanyalah sebuah file kecil biasa tetapi dapat difungsikan sebagai database. SQLite tidak memerlukan sebuah server. SQLite cocok untuk penyimpanan data sebuah device yang smart, untuk keperluan caching. SQLite tidak cocok untuk melayani transaksi database yang kompleks. SQLite tidak boleh dibandingkan dengan database server seperti MySQL, SQLite dapat dibandingkan dengan fopen.

Berikut langkah-langkah mencoba SQLite

  1. Silahkan mendownload sqlite3.exe yang ada di https://www.sqlite.org/download.html  dan letakkan di hardisk anda misalnya d:\sqlite3.exe
     
  2. Membuat database seperti contoh berikut ini:
    D:\qt\dataku>d:\sqlite3.exe dbku
    SQLite version 3.8.10.2 2015-05-20 18:17:19
    Enter “.help” for usage hints.
    sqlite> create table karyawan(karyawan_id int, nama varchar(50));
    sqlite> insert into karyawan values(1, “Visia”);
    sqlite> insert into karyawan values(2, “Gracia”);
    sqlite> insert into karyawan values(3, “Victorine”);
    sqlite> select * from karyawan;
    1|Visia
    2|Gracia
    3|Victorine
    sqlite> .exit

    D:\qt\dataku>dir
     Volume in drive D is Data
     Volume Serial Number is B17C-E100

     Directory of D:\qt\dataku

    07/23/2015  12:36 PM    <DIR>          .
