utilization will continue to allow business and user to optimize the utilization of the Internet and cloud computing. Ways users use applications in the cloud in today’s business environment As information technology continues to improve, applications no longer are limited to being installed locally on a physical computer or server. Cloud computing now allows applications be access via a virtual solution knows as the "cloud". There are many essential characteristics of cloud computing such as on-demand

Today’s businesses can attain applications on demand using cloud computing. Multi-tenancy is a significant feature of cloud computing in which a single application is shared among multiple tenants. Multi-tenancy offers variety of advantages including cost savings, resource utilization, version control and more. Currently more applications are moved from organization’s internal infrastructure to data centers using shared infrastructure that provide Software as a Service (SaaS) to large number of organizations

Each layer has a specific function and the layers work together to allow an application to send data over a computer network without really specifying the exact protocols and/or physical wiring within each layer. In line with the figure above, when the first CEO sends an email message to the second CEO, email ‘application worker’ firstly prompts the first CEO to enter a message and specify that the receiver is the second CEO. The application worker then creates the necessary data package with message

medium fidelity prototypes for software user interfaces. However, there are not that many prototyping design tools that can effectively prototype a mobile application and the Car Checker android application is one of those applications. The search for a usable design tool to design a medium fidelity prototype for the car checker android application has been narrowed down to three software candidates. The three software prototyping tool choices are Dia, WireFrame.CC, and JustInMind Prototyper. One note

2.2) Architectural Styles Software architectural styles are frameworks that have been developed as general solution for the common problems which are arise in the software development process. It is basically defined components, connectors which compose a solution and their relations in a structured program. (Sean Boyd, 2013) (http://kremer.cpsc.ucalgary.ca/courses/seng403/W2013/papers/04ArchitectureStyles.pdf 2.2.1) Client/ Server Architecture The design is made up of two components, Client and

Connolly and Begg (2009) defines a data model as “an integrated collection of concepts for describing and manipulating data, relations between data, and constraints on the data in an organization.” Simply, a data model is a representation of how the different types of data interact. They can be categorized into three main broad aspects, which are object based, record based and physical data

computer software. OS is the software that supports a computer 's basic functions, such as scheduling tasks, executing applications, and controlling peripherals. It is a program that acts as an interface between the user and the computer hardware and controls the execution of all kinds of programs in computer/computer devices. The users of the computer interact with the system and application software which are installed and function in OS. Likewise for the hardware such as Keyboard, printers, mouse, CPU

net computing and data storage service and implemented over the Internet, which is capable of sharing a pool of configurable computing resources with on-demand network access. Cloud technology provides various specific services such as software application, data storage, hardware, and infrastructure. People access Cloud via the internet through web browsers to finish on-demand services, while this was implemented on traditional deploying on-premises servers in old days. Although

kind quite often in our daily interaction with a web application. For example, on a web application like daily motion, a third party comment is an example of untrusted data. Malicious code embedded in such scripts, these requests seem benign on the outside to the web application server; application server returns the data to the unsuspecting user. Web browsers execute

microprocessor. This model is simpler than others but offers tighter security. The MILS model is broken down into four components: A Separation Kernel, Middleware, Applications and a Partitioning Communications System. This structure is similar to other security models as they can have a security kernel which regulates drivers and applications. The aspects that separate the MILS model are its security policies and the way in which they are implemented. (OIS) Unlike the
