Mapping Subsystems to Processors and Components. |
| |
| Processor Mapping: |
| | |
��| |
1.� The Model Subsystem will run on a 300 MHz Pentium II processor with a 21-gigabyte byte hard-Drive.
The chosen hard-Drive size provides the storage space large enough to store the customers' information
for up to five years. Because the Model Subsystem is an entity object, it doesn't need to handle
any major processes; therefore, a 300 MHz Pentium II processor is sufficient.
|
| | |
| |
2.� The Controller Subsystem will run on a 750 MHz Athlone with a 1.1-gigabyte hard-Drive. A 1.1-gigabyte
hard Drive is more than sufficient to store the Controller Subsystem (software). Because the Controller
Subsystem is responsible for transferring and manipulating the data (create boundary object/s
and access data), it must be running on a fast processor in order to accomplish low response time,
high throughput, and high availability.
|
| | |
| |
3.� The View Subsystem will run with the Controller Subsystem on a 750 MHz Athlone processor. The
1.1-gigabyte hard-Drive should have enough storage space to hold both subsystems. The View
Subsystem will be running closely with the Controller Subsystem because the Controller Subsystem
will require to consistently upgrading or creating window/s (boundary object/s) for the user/s to view.�

|
Note: From here on the machine with the 700 MHz Athlone processor will be known as the main system (server), and the machine with the 300 MHz Pentium II is known as the database system.

| Components Mapping: |
| | |
| |
* The Model Subsystem will run on a Unix platform.�This will insure the safety of customers' and
store's information because Unix is known to be stable and reliable in both security and performance.
�
|
| | |
| |
* The Controller Subsystem and the View Subsystem will be running on window 2000 platform. Window 2000
will also provide the security for employees. Each employee will be given a login password to start
the machine.� The manager will be given a special password to check company related information.
Window 2000 is also stable and efficient in performance.
