HRIS SYSTEMS AND SYSTEMS ARCHITECTURE

There are three basic system architecture that are used in the HRIS model which standalone system; data warehouse model; and single integrated model.

Standalone system model is the basic model and it’s operating each unit by their own independent system with no integration. Therefore, business units may send in updates via fax, telephone, mail, or in person. However, this communication may have side impacts such as heavy data entry because there may be a miscommunication with each other. The standalone system model makes more difficult to do a data analysis because the most basic headcount reporting becomes laborious as most of this model are work alone. This type of architecture usually adopted by multinational HRIS model which they are applied the many-headed monster approach. The implementation of this model within each unit in different country has their own authority to modify company policy based on legal requirement. This model is quite common in large, diversified multinational organizations and particularly those that have grown through acquisition. Therefore, this model is not link to each other and problem solving will takes more time.

Data warehouse model is another common HRIS systems architecture but it is more advanced architectural model. The model is using same software systems throughout the units and also run the same version of the software in order to maximizing the resources. The advantages of this architecture model are saving costs through commonality; shared applications; and dealing with the vendor. This model using the same software system would make the data are accurate because it have the data that had been standardized and automatically as opposed by the standalone system models. The limitation is not everyone uses the same database although all users know how the data were generated and what each data element means. The international HRIS model is suitable with data warehouse model architecture.

Single integrated system model also uses the same screens worldwide with appropriate changes for different language in different countries. There is no need for a separate reporting database, although some organizations do options for one in order to separate transaction processing from analytical reporting. This model generally located at corporate headquarters and the data will automatically update throughout the organization. Global and transnational HRIS model will most commonly have a single integrated HRIS. This is because the system is linked together in each department would make them easily connected to each other.
