Konsep Baru Pemodelan Database dengan Anchor Modeling

Konsep Baru Pemodelan Database dengan Anchor Modeling Bowo Prasetyo Contoh Kasus Perubahan Struktur dan Konten Database 10 Desember 2011 http://www.scribd.com/prazjp http://www.slideshare.net/bowoprasetyo

Anchor Modeling ,[object Object]

Berbasis pada empat konstruksi permodelan: anchor , attribute , tie dan knot .

Hasilnya dapat diterjemahkan ke desain relational database, di mana hampir semua tabelnya akan berada pada bentuk sixth normal form (6NF).

Perubahan Database 2 Perubahan Struktur dan Konten Mencatat Masukan Salam

Mencatat Masukan Salam ,[object Object]

dan menampilkan tiga salam terakhir. *) Lihat tutorial “Konsep Baru Pemodelan Database dengan Anchor Modeling – Teknik Pemodelan Database Agile untuk Struktur dan Konten yang Berubah Seiring Waktu”

Penambahan Entitas ,[object Object]

Berarti ada anchor baru yang sesuai, dengan satu attribute teks salam.

Dan tie baru yang menghubungkannya dengan anchor US_User . ,[object Object],[object Object]

Tambah satu attribute : GE_TXT_Greeting_Text

Tambah satu tie bersejarah: GE_wasSaid_US_by

Meng insert Salam ,[object Object]

Pertama buka transaksi database.

Lalu cek salam di tabel attribute . ,[object Object],[object Object]

Insert salam dan waktunya di tabel tie .

Terakhir tutup transaksi database.
