1. 1 Pertemuan 25 Making It Happen Matakuliah: A0194/Pengendalian Rekayasa Ulang Informasi Tahun: 2005 Versi: 1/5

2. 2 Learning Outcomes Pada akhir pertemuan ini, diharapkan mahasiswa akan mampu : Menunjukkan hubungan antara kebutuhan kontrol dengan current architecture

3. 3 Outline Materi Step Three: Chart The Course Isolating and Decoupling Legacy System through Data Hubs

4. 4 Step Three: Chart The Course Establishing the course may seem to be a simple thing to do.

5. 5 Step Three: Chart The Course A straight line in laying out the tactical plan to replace the legacy of architecture with the future state.

6. 6 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

7. 7 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.

8. 8 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.

9. 9 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.

10. 10 Isolating and Decoupling Legacy System through Data Hubs Legacy system change into directly connected architecture by eliminating, simplifying and replacing.
