3

Outline Materi

• Step Three: Chart The Course

• Isolating and Decoupling Legacy System through Data Hubs

4

Step Three: Chart The Course

Establishing the course may seem to be a simple thing to do.

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

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

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

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

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

Isolating and Decoupling Legacy System through Data Hubs

Legacy system change into directly connected architecture by eliminating,

simplifying and replacing.
