CHAPTER 1. INTRODUCTIONIt is known globally that, in today’s market, it is extremely difficult to start a new smallscale business and its sustenance with competition from the well-established and settled/brandowners. Most often, even if the quality of the product is really good, due to a lack ofadvertisement or business at the small scale, it just becomes another face in the sea, and theproduct does not reach a larger group of customers. In fast paced life of today when everyone issqueezed for time, the majority of people are finicky when it comes to doing physical shopping.Logistically, a consumer finds a product more interesting and attractive when they find it on thewebsite of a retailer directly and are able to see item’s details online. The customers of todayare not only attracted because online shopping is very convenient, but also because they havebroader selections, highly competitive prices, better information about the product (includingpeople’s reviews) and extremely simplified navigation for searching regarding the product.Moreover, business owners often offer online shopping options at low rates because the overheadexpenses in opening and running a physical store are higher. Further, with online shopping, theirproducts have access to a worldwide market, which increases the number of customers fromdifferent ethnic groups, adds customer value, and overall sustainable in the marketing.Online web stores, such as Amazon and eBay, have gained huge popularity over the yearsbecause one can buy almost everything at these stores. These web stores also give an opportunityto a lot of small-scale companies and manufactures to reach the global market and to directly selltheir products to people without involving different other companies or middlemen before theirproduct can reach the shelves of a physical store. Further, instead of using the availableplatforms, manufacturers can bring a concept of designing their own web store to sell theirproducts directly to the masses.1
installed on different machines, and students can view the source code for all the different partsshown on the UI to visually understand how a particular piece of code works. This shopping-cartapplication is very versatile and can be enhanced by adding more functions and modifiedgraphics for use with commercial purposes.1.3. Literature ReviewThe history of ecommerce shopping carts began immediately after the World Wide Web,or WWW, became a major medium to communicate information around the world. Ecommerceshopping-cart applications allow consumers to buy goods or services directly over the internetusing a web browser. This online shopping evokes the business-to-consumer (B2C) processwhere a consumer buys directly from the business. The process where a business buys fromanother business is called a business-to-business (B2B) process. The best examples of shoppingcart applications using B2B process are eBay and Amazon, both of which were launched in1995. At present, most users of these online shopping-cart applications are people who havehigher levels of education, have exposure to technological advancements, and are in a betterincome group. Such users develop a positive attitude towards these convenient shoppingtechniques. According to a study in December 2011, Equation Research surveyed 1,500 onlineshoppers and found that 87% of tablet owners made online transactions during the earlyChristmas shopping season. Building a new successful shopping cart is simple because of high competition in themarket, and the designer of a shopping-cart application must consider the information load,complexity, and novelty. Complexity refers to the number of features available on theshopping cart and the levels of marketing, whereas novelty involves the unexpected or unfamiliaraspects of the site. A designer must also consider the consumers’ needs and expectations. A user3
friendly design is very critical to the success of any shopping-cart application because, unlikephysical stores, consumers at online stores come from all ages, genders, and cultures.Logistics clearly says that, to have a successful and profitable online shopping application,businesses have to spend a significant amount of time and money for designing, developing,testing, and maintaining the application. Apart from the high-class design and user interface, agood practice needs to be done to provide quality customer service.A typical shopping cart should contain certain features such as adding items to the cartand checking out those items using the available payment methods. Most shopping-cartapplications are implemented using HTTP cookies or query strings, and an HTML setup isrequired to install the shopping cart on the servers that ultimately hosts the site on the internet.Most of these server-based applications require data related to the items added in the shoppingcart to be kept in a session object which can be accessed later and manipulated dynamicallybecause the users can add or remove one or more items from the cart. Most simple shopping-cartapplications do not allow checkout to be done before any items are added to the cart. Data areoften stored in an external database or application-based databases which can be accessed in realtime by the application administrator.There are many examples of online shopping applications developed in differentlanguages. Choosing a development platform and language depends on policies set by thecompany for which the application is being designed. It also depends on several other factorswhich are very important when considering the platform to design an application, for example,how portable the application will be after being built or if the application is open sourced. Java ischosen for this application because various reasons: it is a simple, robust, and cross-platformlanguage. Applications written in Java can be transported and run on any environment, be it4
MAC or Linux, because Java programs are compiled into platform-independent byte codes.Because of the robustness of Java, it is a very safe language, as they provide exception handlingand a layer method to communicate with the database, which prevents the system from crashingeasily. Another very important factor from the development point of view is that the Javalanguage is object oriented, where everything is treated as an object and where class methods areimplemented instead of functions or procedures, which makes it very simple to understand thecode.Several Java shopping-cart applications were examined, and implementation details werecompared with the proposed design for this application to build an even simpler architecture wasdeveloped which is very easy to understand from the learning perspective. Some online shoppingapplications are as follows: SoftSlate Commerce Commerce4j Cs.Cart Apache OfbizThese applications are designed for industrial purposes to generate revenue by providingthese applications to customers looking to launch a website for their respective businesses.The application proposed in this paper is more focused on developing a simple, yet complete,application specifically designed for computer science students to learn the basics aboutapplication design and development. This application performs all the basic functions that theabove-mentioned applications do, such as selecting an item and adding it to the shopping cart,user login or registering, checkout of the item, etc. Other functions that can be added to thisapplication are proposed in the future work, and they would be necessary under a more complete5
and complex design. The final application is expected to teach students enough to start them on acourse to implement more complex functionalities, as mentioned in the Future Work.1.4. Paper OrganizationThe rest of the document is divided into three parts: Objectives, Implementation, andTesting. The Objectives chapter lists the need for building the system. It provides use cases tohelp the business and technical users with their understanding. It also gives a detailedexplanation for each use case to help with design and implementation, and outlines theconstraints regarding the software. The Implementation chapter contains the detailed design ofthe system, including the Class Diagram, Activity Diagram, and Component Diagram. Thischapter also includes a detailed explanation for each component as well as the interaction of theclass and its components with each other when carrying out certain tasks, besides software’smock screen shots.6
CHAPTER 2. OBJECTIVESAll the steps required in the software-analysis process related to this project (productfunction, user characteristics, functional and nonfunctional requirements, constraints,assumptions, and dependencies for the online shopping cart application) are described in thefollowing sections.2.1. Requirements AnalysisThe requirements analysis and gathering processes are critical for the success of anysoftware engineering project. Requirements analysis in software engineering is a process thatdetermines the tasks that are required to determine the needs and conditions to design a newproduct or to make modifications in any existing product/application. This process considers allthe stakeholders’ conflicting requirements, and analyzes the documentation and validation of thesystem. The requirements should be actionable, measurable, testable, and related to the definedneeds of the system design. From the software-engineering perspective, requirements analysis isa three-step process.1.Requirements Elicitation: Elicitation of requirements, also known as requirements gathering,includes the task of identifying various requirement types from stakeholders or from projectdocumentation.2. Requirements Analysis: Analysis of requirements determines if the gathered requirements areclear, complete, and consistent. The analysis also handles any ambiguous requirements thatdo not clearly state what needs to be implemented, which could create a loss of resources andtime if identified later in the development or testing phase.Requirement analysis requires identifying the stakeholders and taking their needs intoaccount to help them understand the implications of designing the new system, along with7
what modules are worth implementing and which ones are more cost efficient, and then tocreate a software-requirement specification document. To clearly elicit the stakeholders’requirements, different processes, such as developing a scenario or user stories, andidentifying the use case which is being used for the project, can be utilized.Stakeholder analysis says that, to clearly gather the requirements of the project, analystsfirst need to identify the stakeholders. Stakeholders are people or organizations that have avalid interest or use in the system. The steps to identify the stakeholders are as follows: Anyone who operates the system. Anyone who benefits from the system Anyone who is directly or indirectly involved in purchasing the system People or organizations opposed to the system Organizations responsible for the system design Organizations that regulate the financial or safety aspects of the systemOnce the stakeholders are successfully identified, interviews are conducted throughdifferent processes; the needs and requirements of the system are identified, and arequirements specification document is prepared. The document is then discussed with themajor stakeholders to identify any ambiguity with the requirements and understanding of thesystem.3. Requirements Documentation: This step involves documenting the requirements invariousforms, including summary lists, natural language documents, visual documents,use cases, user stories, or process specifications. A requirement specification document iscategorized in different ways according to the stakeholders’ need, helping to create a clearcontract between development and business. The following sections include the different8
categories of requirements specification document that are essential for designing thisapplication: the functional requirements, constraints, system requirements, etc.2.1.1. Product PerspectiveThe online shopping-cart application is a web-based system. It can be accessed usingInternet Explorer 8.0 and above, Mozilla Firefox 2.0, and Google Chrome.184.108.40.206. User InterfaceThe two interface types found in the online shopping-cart application are as follows:1. User Interface: Users are able to view the home page of the shopping-cart application,browse the different categories, browse and add any number of items from any categories inthe shopping cart, look for information about each product, delete the items in the shoppingcart, save the cart for later viewing, check out or continue shopping after adding the item tothe cart, and check out the items by completing the required information in the order form.2. Admin Interface: The administrator is able to view the users’ information that was enteredduring checkout in the database, can update the information, price, shipping costs of theitems, add or remove items from the main display.Both interfaces are described, in detail, in the External Interface Requirement section ofChapter 220.127.116.11.2.
