The architectural model of the computer system presents the logical arrangement of deploying the software components on the hardware to achieve the goal of the software application. It describes the software components include: the database, the logic for accessing the data, and…
The detailed architectural model is used to achieve the level of security in the system, the performance of the system as well as the effectiveness and efficiency (Coulouris, Dooimore, and Kindberg, 2001).
There are three (3) forms of the system architecture include: the client based, server based and the client-server architecture. As the proposed system for ‘Electronic Credit Checking and Mortgage Approval’ is online, therefore, I have chosen the client server architecture.
The client-server architecture for the proposed system that presents the client has to place a request to the web server by utilizing the web browser (Internet Explorer, Google Chrome, etc.). The web browser takes the Hypertext Transfer Protocol (HTTP) request, Files Transfer Protocol (FTP), data, etc. to the web server of the Mortgage Company; the web server would interact with the database server for the relevant information. The database server would send a SQL query to the database and the database returns the information against the query. The database server would reply to the web server with the information received from the database. The web server would display the information on the web browser of the client. The web application would be deployed on the web server or application server; the database server would contain the database as shown in the following diagram (Kambalyal, n.d).
The system architecture that has been used for deploying the web application is 3-tier architecture that provides higher flexibility; high security can be implemented at each level of the service, and high performance due to sharing of tasks between servers, moreover, it can be extended (scalable) with the requirements of the Mortgage Company (Kioskea, 2012).
The client has to use the web browser to access the web application over the internet, in order to provide security the client’s request has to be passed through the firewall deployed ...

Above their guidance, managerial and conceptual skills I thank them for their encouragement, patience and support. I am privileged to have attended the course of ‘Design Principles’ with Mr. Peter Sun as its instructor who made sure that each of his students got the clear perception and understanding of the concepts and skills of the principle concepts in the course.
Though some principles of job design that are required to make jobs more motivating while leading to high employee performance were recognised since the mid 1970’s, it can be noted that some companies continue to design the job along the Tayloristic principles. As such, this essay seeks to critically analyse the significance of job design and how it impacts on human resources in a particular organisation.
It describes the software components include: the database, the logic for accessing the data, and the user interfaces; moreover, the architecture model explains the hardware includes: diverse computer servers and clients / users’ computers. The architectural model is the graphical representation for understanding of the system and reviewing that whether the system fulfils the user’s functional and non-functional requirements.
Detailed design as explained by IEEE is is the act of making improvements on already designed software so as to make it suit the intended purpose (34). In the process of detailed design, designers thoroughly explore each element in order to define the core structure and behavioural capabilities of the software that would result in the construction of efficient and natural software.
It refers to the feasibility study of the product in terms of outcomes of the product, operational use and technical support required for implementing it.
The purpose of instructional design analysis is to know that the design strategies adopted by the management are efficient or not.
This paper will demonstrate with the help of a case study and illustrations, various factors involved in structural stability of a structure.
Failure analysis is a time consuming and an absorbing subject. Finding the true cause of a structural collapse require an expertise.
Constable studied at the Royal Academy in 1799 (Wilson n.d.). Most of Constable’s notable works were sketches and paintings of nature. Wilson (n.d.) explains:
Once in London, Constable studied Old Master landscapes in the collections of Beaumont, Beckford
A major environmental issue caused by the development of a major highway through Centre County Pennsylvania resulted in the pollution of the public’s drinking water as a result of acid rock (Joseph). Sky Top Mountain is a unique geological setting though contractors were originally unaware of the pyrite veins located in the area.
