Architecture design is used to define how options can be used to improve the hardware and software specifications. This paper will describe the application architecture and process design. A detailed observation is necessary to determine what kind of hardware can accommodate the software and it is a critical part of the system development life cycle. A high-level explanation of the security controls suggestions will be included.

Application Architecture and Process Design
The first step is to identify the major software components of the system being developed. Software systems are divided into four major functions. Data storage in an Information System stores the data or file. Data Access Logic is managing needed to retrieve the data. Application Logic is the processes or activities that are executed. The final function is the Presentation Logic function which is the presentation of the information and the user interface. Knowledge of the functions is vital in the design process and the data flow diagrams (DFD). Architecture design begins with the non-practical necessity. Riordan Manufacturing, Inc. is a large corporation that consists of several locations and the use of a Client-Server Architecture would be best due to scalability, which refers to flexible capacity of the infrastructure. Large-scale software is projected to be used by thousands of people concurrently. The cost of the infrastructure in a Client-Server is typically lower due to the hardware, software, and networks that will support the system (System Analysis Design). Personal computers have faster processing power and can be used to assist the load on the network. Constructing this model for Riordan is a substantial amount of work and a n-tiered architecture will allot the job among more dedicated computers. Nonfunctional requirements can be categorized as operational, performance, and security. Access by employees to make address changes or other types of...
