Usability testing is an important part of designing a user interface. To ensure the interface is fully effective, the usability testing is best done throughout the whole designing process as well as during implementation. During the software life cycle, designers can go back at any time to make corrections.  It’s very important to perform testing, because it prevents major errors, and makes the software run smoothly (Edrington, 1999). There are four principles for usability testing: Efficiency, accuracy, recall and emotional response. The best way to describe the benefits of usability testing is to explain how each of the four principles work.

 It is vital to use the software requirements elicitation process when developing a system, because if it’s not followed the end product will not be right for a client and the end-user. That is a waste of the client’s money and resources, and the software development team’s time, not to mention, aggravate the customer. It would be bad if this happens. Using the software requirements elicitation process eliminates errors, and inadequate software. That’s why it’s so important.

Test Specification Development

The biggest contrast, and comparison, between Structured Design programming and Object Orientated programming is that Structured Design programming works by breaking down big problems into small ones. Then it breaks down the small ones into even smaller ones and so forth, until they are small and simple enough that a programmer recognizes it and is able to work with it. OO programming works by grouping codes with data that it operates with. It then operates independently of the rest of the system. The interesting thing is that Structured Design and Object Orientated programming are not exclusive mutually, because you can structure coding in an object and use objects to implement modules of code in a structured program.

The impact of retailing online has been significantly large. As far back as in 2008, a retailer’s sales were increased by 20% just from online purchases (Charlesworth, 2013). It has been noted that the percentage has climbed even higher in the past couple of years. It is anticipated that it will climb even higher in the years to come. This high impact on retailing online is due to the fact that retailers are able to reach hundreds (sometimes thousands) of customers across the web and the availability of many more products than most traditional (physical store) retailers can offer in one place. It’s also because products online are more convenient for users as they don’t have to physically go get the product (Vannier, 2013). It can just be mailed to them. Also, online retailers seem to have the advantage of cheaper prices. The availability of many products, along with cheaper prices, allows internet retailing to have a huge impact.

Enterprise Content Management (ECM) is organizing and collecting information to be used by a certain audience such as customers or business executives (Aiim, 2015). It isn’t a single methodology or technology. But what it is, is a combination of them that can be used as a tool to manage, preserve, capture and deliver information that can support key organizational processes through its lifecycle.

Data Warehouse overview

Supervised Learning Overview

Cloud computing in simple terms is computing services that include storage, databases, software, networking, and analytics delivered over the internet which is also known as "the cloud" (Ranger, 2022). Cloud services are when organizations rent applications, storage, and other services from cloud service providers instead of having their own infrastructure and data centers. Cloud computing is quickly becoming the default option for applications and software vendors offer their products and services over the internet now instead of standalone products.

The Web (World Wide Web) is known in the information technology field as a subset of the internet with pages that are accessed by web browsers (Techopedia, 2022). This is not the same as what is defined as the Internet. The Internet is defined as the global network of servers that make it possible for users to share information over the Web. The Web is a large part of the Internet, but it is not the same thing. The question now would be where is the data stored that is accessed by users to share over the Web? This would be where the web-based database management system would come into play.

Simply put, database theory is database study. A database is a set of digital data that is stored and accessed in several ways. Database theory covers different aspects that has to do with databases including database management and several level of abstraction of data (USFHealth, 2021). A database is used to enforce standards and maintain data integrity. It is a repository of data which is stored in tables and made up of a lot of data that has some connection to each other. The data in the database is structured in a way that is easily accessible to computer programs and users.

Over the last several years data breaches have risen considerably. Organizations have become more aware that database security is essential. Database security involves protecting databases and their management system, their web applications, and the data the database contains (Database security, n.d.). It is an organization’s responsibility to ensure its database is protected from external and internal threats. Internet-based attacks are one of the biggest challenges to database security. Cybercriminals are constantly devising new ways to infiltrate databases to steal, delete, or modify data by attacking web applications to get to the organization’s database. The motivation of this research is to find the two topmost critical vulnerabilities so organizations can devise ways to minimize them if not eliminate them.
