HRIS SYSTEM AND SYSTEM ARCHITECTURE

            System Architecture is the conceptual model that defines the structure, behavior and more views of a system. It is a response to the conceptual and practical difficulties of the description and the design of complex systems such as an industrial system, IT infrastructure, organization, business and project. Systems architecture will often rely on a tool called architecture framework, which is a reference model to organize the various elements of the architecture of a system into complementary and consistent predefined views allowing covering all the scope of Systems Architecture.

According to Beaman, Karen V. (2004), System architecture have three types of system with four HRIS model which are standalone systems, data warehouse model and single integrated system model. Each model has specific function to an organization. The three models have their own specialties. The selection of the models is depends on the organization which it deems appropriate to their organization structure whether the organization multinational, global, international or transnational organization in using HRIS system architecture.

            In standalone system model is a single function runs in particular way which identify multinational model that is ultimately localized and highly decentralized.  Operating units will send the information independently by each organization to the global data warehouse. This model clearly identified a company as a Multinational HRIS model. This model is quite common in large, diversified multinational organization, particularly those that have grown through acquisition. This model is quite difficult to analysis data because taking a lot of time and effort and also only little control at the centre.

Data warehouse is related to international HRIS model. In this model, all operating units use the same software systems in order to reporting the information for each regional or country data warehouse. Global data warehouse will receive the report or information from regional. This model can increase resources in order to reduce the cost with standardized data such as sharing knowledge, commonness and standardized format but not everyone uses same database.

Besides that, a single integrated system model is related to global and transnational HRIS model. It is appropriate for global and transnational HRIS system because these types of system use the same screen worldwide which it is will adapt to the changes for different language in different countries. This model is most advances rather than data warehouse model and standalone model. There is only one instance of database that located at corporate at corporate headquarters. Updating any information for each branch or franchise the system automatically updates it throughout the organization.
