Assume that you work for a consulting firm which offers information technology and database services. Part of its core services is to optimize and provide streamline solutions for efficiency. In this scenario, your firm has been awarded a contract to implement a new personnel system for a government agency. This government agency has requested an optimized data repository for its system which will allow the management staff to perform necessary human resources (HR) duties all along with the capability to produce ad hoc reporting features for different departments. They look forward to holding data which will permit them to perform HR core functions like hiring, promotions, policy enforcement, benefits management and training.
By using this scenario, prepare a three to four page paper in which you:
Find out the steps in the development of an effective Entity Relationship Model (ERM) Diagram and find out the possible iterative steps or factors which one must consider in this process with consideration of the HR core functions and responsibilities of the client. Analyze the risks which can take place if any of the developmental or iterative steps of making an ERM Diagram are not performed. Choose and rank at least five entities which would be needed for the development of the data repositories. Specify the components which would be needed to hold time-variant data for policy enforcement and training management. Diagram a possible 1:M solution which will hold salary history data, job history, and training history for each employee via the use of graphical tools in Microsoft Word or Visio, or an open source alternative such as Dia.
Note: The graphically depicted solution is not comprised in the required page length. Plan each step of the normalization process to make sure the 3NF level of normalization by using the selected five entities of the personnel database solution. Document each step of the process and justify your suppossitions in the process. Diagram at least five possible entities that will be required to sustain a personnel solution. The diagram should include the following: Dependency diagrams Multivalued dependencies
