Pertemuan 25
Making It Happen
1
Learning Outcomes
Pada akhir pertemuan ini, diharapkan mahasiswa
akan mampu :
• Menunjukkan hubungan antara kebutuhan
kontrol dengan current architecture
2
Outline Materi
• Step Three: Chart The Course
• Isolating and Decoupling Legacy System
through Data Hubs
3
Step Three: Chart The Course
Establishing the course may seem to be a
simple thing to do.
4
Step Three: Chart The Course
A straight line in laying out the tactical plan
to replace the legacy of architecture with
the future state.
5
Step Three: Chart The Course
The Steps to Chart:
• Isolating and Decoupling Legacy System
through Data Hubs.
• Warehouse and Decision Support System
as interim integrators
6
Isolating and Decoupling Legacy System
through Data Hubs
The first time you create a hub, you actually
make the job a little harder, which makes it
difficult to gain support for this approach.
7
Isolating and Decoupling Legacy System through
Data Hubs
Direct Connection Replace direct link
between house #1 and #3  Replace
direct link between house #2 and #5  All
directs link removed.
8
Isolating and Decoupling Legacy System
through Data Hubs
Since we have to rewrite the links anyway,
we just write ht links to the hub instead of
to each other.
9
Isolating and Decoupling Legacy System
through Data Hubs
Legacy system change into directly
connected architecture by eliminating,
simplifying and replacing.
