Evolusi pengembangan sistem informasi

Membangun sebuah sistem informasi, memang tidak bisa dikatakan mudah. Permintaan calon user yang sering berubah-ubah, waktu yang diberikan, biaya dan sumber daya yang terbatas seringkali membuat pengembangan sistem harus dilakukan dengan menggunakan pemilihan metodologi yang cocok.

Metodologi dapat diartikan sebagai sebuah pendekatan formal atau sebuah rangkaian langkah dalam mengembangkan sebuah sistem. Pemilihan sebuah metodologi sangat tergantung terhadap dua hal yaitu berorientasi kepada bisnis proses atau object data. Menulis sebuah kode tanpa berpikir panjang mungkin bisa dilakukan pada program yang kecil, namun hal ini jarang terjadi pada program yang besar.

Metodologi yang menggunakan pendekatan proses bisnis lebih fokus pada pendefinisian setiap aktifitas yang mendukung sistem tersebut. Metodologi ini lebih menekankan bagaimana sebuat proses yang membutuhkan input dan mengeluarkan output dari system.

Sedangkan metodologi yang menggunakan pendekatan pada object data, lebih menekankan bagaimana data diorganisasi dan konten data yang ada di dalamnya.

Dewasa ini dikenal banyak sekali metodologi yang digunakan dalam pengembangan sistem informasi.

Beberapa yang dikenal antara lain :

  1. Structured Design
    • Waterfall
    • Parallel
  2. Rapid Application Development (RAD)
    • Phased Development
    • Prototyping
    • Throw-Away Prototyping
  3. Agile Development
    • Extreme Programming
    • Scrum

I Lost my Money to scammers but not anymore

Well, who would have believed this. When I saw a comment

by one Allison babara, I thought it was one of the Scammers

ways to convince someone. Looking at his comment, I saw

an element of doubt since he was telling stories. Well I did it

50/50 which means I can’t lose my money to any scammer

again. I contacted the email on the testimony of Allison?

Babara (securehackers01@gmail.com) and I was

replied immediately. I was shocked but I didn’t lose my stand.

I asked them to give me proof to be sure they are not

scammers like others that I have met before and they sent me

a proof. Then I requested to get my card which they sent to

me in Germany in just 3 days. Am happy now because I have?

recovered my cash I lost to scammers. My first withdrawal?

was $10,000 and I couldn’t believe my eyes until I confirmed?

their word which says that I can withdraw up $63,000 in a

month. secureblankatmSolution? are real because I got my?

card in just 3 days when I requested for one. Contact their

mail (securehackers01@gmail.com ) for yours. They

didn’t scam me.
