Connection protocol - server specifications

Second group meeting for CISD assessment report No2

Yesterday we had a meeting again. Everybody were happy with the new network that I had design so we have start searching for our company servers.(type-specifications) We found the most appropriate servers for our network by looking their specifications and their cost as our company is a medium business which afterwards will be expanded.

The serves of our network so far:

Backup server: Dell Equal logic PS6000 XV ISCSI Array

Application Server: Dell power Edge M905 Blade server

Direct Server: Dell PowerConnect PC 3548

Architecture:

Applications + Data server (cluster architecture)

Backup Server (multicomputer architecture)

However we started the description of the network and we have finished the connection protocol part.

Meeting duration: 1.00-3.00 pm

Network Design

When I saw the network we had designed, for a second time I realized that it was wrong, so because I am the person who must design the network for the next meeting I decided to design my own one according to the book SYSTEM ANALYSIS & DESING IN A CHANGING WORLD page 338. Below is the network diagram that I have designed in my pc. Again is not fully complete because we need to decide what software it must run the database server, the workstations PC and the web/application server. On the other hand the bellow network, in my opinion has the correct network architecture.

Event tables again........

The report is getting more complicated instead of being easier. I have found more and more incorrectly created things in my assignment .For instance the event table has to be separate for each stakeholder and not used in the use cases in one table. It took me many hours until i corrected it!i created 4 separate event tables until now for customer,valuer,vendor and office staff. Hopefully these would be my last event tables because I have recently been told of the correct way of writing the report from my lecturer.

ERD diagram and corrections

After Fridays tutorial lesson i supervised by my tutor that my report has small mistakes.I have corrected my Event table and i have change some of my use cases. Moreover i have change their names.In addition i finally understood what the is ERD(Entity Relation Diagram) and i have created but with difficulty .To achieve that ,the form which was attached on the case study and the case study were very helpful. They give us the keys which each object must include.On the left is an example of ERD diagram.

Use case tables "Property Valuation" and "Notify Office Staff"

As i am going through the report is getting difficult. I haven't worked much with my report this week because we bombarded with many other assessments and test on the other hand , i have created another 2 use case tables with the names"Notify Office Staff" with actor the vendor and the second one "Property Valuation" with actor the Valuer. Moreover i have done some correction to my very first one use case"Create new offer" because of the fact that it was very complicated.

Use case tables-Activity diagrams-Event Table

According to my tutor i noticed that my activity diagram was needed some corrections.I change my activity diagram and i have created another 3 activity diagrams.Moreover i have create one main use case and i started the first individual use case "create new offer" .I have spend many hours to understood how it must be done and what steps must be include.I believe that i have mistakes but i would come back to that point after the next tutorial lesson.In addition i created also an Event table which is also need corrections.
