Application Architecture and Process Design
Riordan’s HR information is comprised of eight separate systems with system having separate processes to access and manage the data. The proposed HR system will be a single integrated application (Apollo, 2006). In order to achieve this, a completely new HR system is needed in order to meet the required. A specific software platform has not been chosen yet, as there are many in the market that is suitable for Riordan’s needs. Ascentis HR software provides a suite of software that integrates with each other, is easy to use and set up, and comes with hundreds of out of the box reports (Ascentis, 2012). PeopleSoft is an Oracle product that has a huge market and is designed to meet even the most complex business requirements (Oracle, 2012). There are many more that provide varying degrees of features, complexity and ease of use. The proposed system will be a server-client based infrastructure. The base server hardware specification will be configured to follow the hardware specifications for the specific HR software. For ease of installation, management and out of band administration, HP DL360 G8 servers will be used (Hewlett-Packard Development Company, L.P., 2012). The base operating system is Windows 2008 R2 with Service Pack 1. The default database used will be Microsoft SQL 2008 R2, unless a specific version of a database is required. To account for high availability and load balancing, a minimum of four servers will be used for the new HR system. Two servers will be used as a clustered database instance. The other two servers will be used as a clustered and load balanced web front-end. The software solution for the HR system is a single instance that encompasses all aspects and departments within HR. The system will use a role based access control (RBAC) model so that only authorized people can view HR information and edit the...
