How do you define application architecture and process design? Wise Geek defines application architecture as “the organizational design of an entire software application, including all sub-components and external applications interchanges. There are several design patterns that are used to define an application architecture” (wiseGEEK, 2013). The design patterns are created to meet the objectives described in the system requirements. “The activity of determining the workflow, equipment needs, and implementation requirements for a particular process,” is the definition of process design. “process design typically uses a number of tools including flowcharting, process simulation software, and scale models” (BusinessDictionary. com, 2013).
The complexity of the application architecture and process design of the Riordan Manufacturing HRIS is actually more simplistic.
The first step is to refine the nonfunctional requirements into more detailed requirements that are then employed to help select the architecture to be used and the software components to be placed on each device” (Dennis, Wixom, & Roth, 2009).
Riordan Manufacturing’s HRIS will benefit most utilizing client-server architecture. Dennis, Wixom, & Roth, 2009 explains that, “Client-server architectures have four important benefits. First and foremost, they are scalable. That means it is easy to increase or decrease the storage and processing capabilities of the servers. Another benefit is that the client server architecture supports a number of clients and servers. “It is possible to connect computers that use different operating systems so that users can choose which type of computer they prefer” (Dennis, Wixom, & Roth, 2009).
The Essay on Summary and evaluation the importance on sketching in design process
In the article, ‘The Backtalk of Self-Generated Sketches,’ Goldschmidt discusses and talk over how we as human especially designers and artists use drawing and sketching to help us to generate ideas and also strengthening them by interpreting the ‘blacktalk’ of a sketching process. The article shows that the backtalk of a self-generated sketch gives rise to novel information that is not deducible ...
Thirdly, client-server architectures logic is being separated and used. “Likewise, it is possible to change the application logic without changing the presentation logic or the data, which are stored in databases and access by SQL commands” (Dennis, Wixom, & Roth, 2009).
And lastly, the network is many times more stable and reliable due to all applications being supported my more than one server. “If any one server fails in client-server architecture, only the applications requiring that server will fail; the network will continue to function with all the other servers” (Dennis, Wixom, & Roth, 2009).
A normal client server design is shown below. Typical Client Server Design Security Controls Security is becoming increasingly important as technology becomes more sophisticated. “Security is primarily the responsibility of the operations group.
The staff responsible for installing and operating security controls such as firewalls, intrusion detection systems, and routine backup recovery operations” (Dennis, Wixom, & Roth, 2009).
Not only does the operations group have a responsibility in the security of business technology, system developers are equally responsible. “Developing security usually starts with some assessment of the value of the system and its data” (Dennis, Wixom, & Roth, 2009).
System Processes Application processes can benefit utilizing third-party software. Hence Riordan Manufacturing can also have the security guarantee of the third-party vendor.
My Staffing Pro is a program that tracks and screens applicants and allows for improved management of job postings (My Staffing Pro, n. d. ).
The Essay on All-in-One Computer Security Systems
All-in-one Computer Security Systems CIS/105 Some of the different programs that I choose to use as all-in-one security that has total protection are Norton Internet Security and McAfee has an exclusive active protection technology that analyzes and blocks threats in milliseconds. McAfee can immediately detect and remove viruses, even root kits, adware, spyware, and blocks. McAfee has a two-way ...
This would increase Riordan Manufacturing efficiency in employee application process by saving time and lowering costs of going a different route. The software also has the ability to generate ad hoc reports like equal employment opportunity reports. Data Data encryption and passwords should be utilized for those who have authorization to access the HRIS system because Riordan Manufacturing is responsible for all data relating to procedures and employee information.
Security and confidentiality is a must when it comes to utilizing data. “The lawsuits alone would easily exceed $10 million and the cost of staff to find an reenter paper records would be enormous and certainly would take more than a few weeks” (Dennis, Wixom, & Roth, 2009).
Network The most secure networks are those that incorporate a virtual area network. This allows updating of information by employees and approvals or verification of those updates by authorized personnel. Access to this information calls for password and username protection by way of 128-bit encryption standards.
If further, more detailed information would need updating or change, an authorized person will be required to input their information, including fingerprints. This is called multi factor authentication. Data Flow Diagram As the information system is designed, implementation decisions describing how the system will work are made. Data flow diagrams offer those implementation details, including data stores that refer to files and database tables, programs and human actions that perform processes. The automated parts of the system are differentiated from the manual parts by the human-machine boundary.
