Learning Outcomes
Pada akhir pertemuan ini, diharapkan mahasiswa
akan mampu :
• Mahasiswa dapat Memberikan definisi
perilaku sistem (C1)
• Mahasiswa dapat Menghubungkan pola
behaviour (C3)
• Mahasiswa dapat Membuat diagram /
skema Statechart (C4)

Definisi
• Event Trace
– Urutan dari event yang terjadi pada suatu
object
• Behavioural Pattern
– Daftar kemungkinan event traces yang terjadi
pada semua object didalam class
• Attribute
– Keterangan property dari class atau event
6
Menjelaskan Behaviour
• Perlu dibuat untuk setiap class
• Coba buat typical behaviour (event trace)
terlebih dahulu, baru kemudian ditambahkan
behaviour yang ada
• Hasilnya adalah behavioural pattern
– Kumpulan pola event dari kemungkinan urutan event
untuk object didalam class
• Ditampilkan dengan menggunakan statechart
• Dapat ditampilkan dalam bentuk lain
– regular expression
– state table

Explore Patterns
• The Stepwise Relation Pattern
– Digunakan untuk associations dengan
agregation multiple level
• The Stepwise Role Pattern
– Digunakan untuk lifecycle yang menambah
peran baru
• The Composite Pattern
– Digunakan ketika part dapat ditambahkan
secara rucursive
