Introduction
Application architecture is the organizational design of an entire software application. This design includes all sub-components, as well as external application interchanges, and is designed to meet the objectives of the system requirements, set forth by the client and stakeholders at hand. The current goal and objective is finding out the best design for the company. Riordan’s current HRIS system is functional, at the least, but with the right design, could be transformed into an amazing application.
Riordan Operational Requirements
Riordan must integrate the new HR CRM system with current software. Since the system requires integration with employee’s desktop computers, a client-server architecture would be most beneficial. This would allow for better storage, flexibility to allow different OS to connect, and reduction in costs which is a long term benefit for the company. The client-server architecture would be best to integrate employee desktops.
Riordan Performance Requirements
Riordan is interested in a high-tech system to integrate the mountains of Human Resource forms and documents. They expect high performance in their new integrated system. This is the reason why we have chosen the client-server architecture. Due to increased scalability, availability, reliability, and better response times with this architecture, Riordan will benefit by easier integration of hardware and speed requirements of the comprised systems. Since the aforementioned features greatly depend upon the operating system utilized, Riordan will upgrade to the Microsoft Windows 7 operating system (Wixom Roth, 2014).

Riordan Security Controls and Requirements
The client-server architecture will increase Riordan’s security due to the fact that all software will be housed in one location, making mainframe operating systems more secure. Using advanced authentication and encryption controls, Riordan will benefit from this advanced architecture by reducing potential issues with viruses and malware that is running amok on the World Wide Web. Protection is guaranteed not to spread across employee desktop computers because software is not housed on the client device, but rather the server-based architecture model (Wixom Roth, 2014). Due to the sensitivity of Riordan’s business and employee data files, assurance must be given to the privacy and confidentiality of data records. Internet-based employers who deal with human resource information must take the possibility of attacks seriously. Many of the security breaches, according to the Federal Bureau of Investigation (FBI), have come from within the organization. Riordan must decide who will have access to data and how much access each employee is provided. According to the FBI.gov (2013) website, companies can enhance security of data by doing a few things. First, use screening processes to select new employees, with through background checks. Second, educate and regularly train employees on security protocols and routinely monitor computers for suspicious activity. And third, ensure that confidential data is protected, and ensure that all security personnel have the tools they need.
