 HRIS Systems and Systems Architecture

Hello, today I want to share my experience in doing group assignment title HRIS Systems and Systems Architecture.  We been given 1 week to prepare it and present it in class.  We get the assignment at 1/10/2012 that in week 4 and present at 8/10/2012 in week 5.

Seriously, when I read the question, I cannot get any idea.  Then after searching between the group members, it gives the simple understanding from me to all of you.  The 3 types of HRIS system architecture is STANDALONE SYSTEM, DATA WAREHOUSE MODEL AND SINGLE INTEGRATED SYSTEM.

For Standalone System, it cannot be standardized.  Usually, it used by large organization.  This is because this organization well gathers in multinational data.  In addition, every branch must provide the data to the global data warehouse.  For the business, each business unit can update via fax, telephone and so on.  it also  make difficulties for each unit to data analysis.  From my view, because this system an independent system to communicate, it very hard to work n connect.   

Next, let’s see the Data Warehouse Model.  It also known as DW or DWH.  In this model, the benefits of this model is maintain data history, even if the source transaction systems do not.  Other than that, it provide a single common data model for all data interest.  So that, it can save cost and  sharing each other.  Normally, the data stored in the warehouse are uploaded from operational system such as marketing, sales and so on.  When we talk in term of international, this model is suitable because it match.  And the analysis that we use are also same.  Therefore, it easy to analyse.

The third is Single Integrated System Model.  This definition of an Integrated System is  identifies characteristics arranged in the broad categories of  Data Issues, Application Issues, Presentation Issues, and Operational Issues.  Normally, it located as the corporate headquarters.  In addition, this model more advance because it can sharing information. This model is more advances compare the others model. 

From that explanation, what can I says, if we want to related with transnational, the model are Single Integrated system model, while we talk the international, the model that suitable are data warehouse model.  In addition every organization have their own difference between their model that there are use to run the business.  The organization must choose the best and the most requirement that organization needed.  Sometimes, I confused to differentiate it more clearly.  But, I must take an initiative to further more explore and understand in this topic.
