1. Introduction & objectives 1.1 Introduction 

“Sara “Sarasa savi vi book book selle sellers” rs” is the book book selli selling ng divis divisio ion n of Saras Sarasav avii Group Group of companies in Sri Lanka.



It was established in 1955.



Recently it won the state award for the best bookshop in Colombo and its suburbs.



Since they strive to maintain excellence in customer service and customer satis satisfac factio tion n they they guar guarant antee ee the cond conditi ition on of every every book book deliv deliver ered ed to the the customer as the item will be dispatched after thorough examination.



To facilitate the customers to order a particular book without wasting time to visit the bookshop, they use an online purchasing system for the company.



Books are reasonably priced and most of the best selling Sarasavi books are made available online at the Sarasavi.lk website for world wide shipping.



The existing system uses a Point Of Sale (POS) System to input the bar code entry and manual entry at the cash counter to input sales item code to the system. Through the company website, the customers can perform online book purchase.



The customer can search for a particular book or a magazine via the Book title, Author name or by the Edition.



The customer can view the latest arrivals such as new novels, story books or magazines.

Objectives

The main objective of the system is to integrate a comprehensive book reservation system for Sarasavi Bookshop existing website and also to introduce a new tracking device which uses radio wave based tagging system which is known as RFID (Radio Frequency Identification) technology. While this is the main objective, the system design should adhere with the following objectives. 

Enhance day to day businesses  Feasibility of implementation  Scalability and extendibility.  The system must win the confidence of the public

Enhance day to day businesses 

Day to day business activities will be easier with the RFID technology because repetitive input of item details might be avoided by this new technology.



Along with item-level tagging it reduces the risk of books being out of stock and it gives the ability to track which books are flying off the shelves and which haven't moved in a while.



In addition, taking an inventory will become less of a headache and it would not be necessary to shutting up of shop for stock taking purposes.



All the above uses allow the company to take competitive advantage from the environment and allow to increase the company’s productivity.



Since the company uses a website the company should be benefited from it in its business perspectives such as increasing promotions for the company, competitive advantage, increase of sales, new markets and etc.



Since Since the booksho bookshop p is maintai maintaining ning sales sales details details,, differe different nt statisti statistical cal analysis methods can be used to analyze the trend of sales.



With this bookshop can publish about the “Best Seller” books weekly or monthly as the company needs.

6

Project Proposal




This permits the readers to know about the latest trends in the society and go for them, which indirectly increases productivity.



Also with data mining company can identify the probable book/books a regular customer is going to buy and also can analyze who are the probable customers of a new release and let them know via Newsletters.

Feasibility of implementation 

This This syste system m is devel develope oped d to enha enhance nce comp company any activ activiti ities es from from the existing manner of performing into a digitized format through the use of Internet and desktop computers.



The system must be able to implement implement with a feasible budget affordable by the project sponsors.



For example the system cannot afford to use a satellite aided parcel tracki tracking ng syste system m to moni monitor tor whet whether her the book book parce parcels ls orde ordered red are deli delive vere red d to the the corr correc ectt cust custom omer er or not, not, monit onitor or secu securi rity ty nor nor implemented artificial intelligence which regularly examines whether the parcel is delivered to the correct place or got misplaced on the way and reflect those changes into the system by regular examination of the geographical changes in the city and roads.



Since the proposed system tries to eliminate the useless traverse for building a payment gateway within the own domain, the system will have to store Credit card details within the customer details data store.



This is less cost and easy to implement than a payment gateway and but to provide security and privacy different approaches should be taken. The site has to use standard Secure Socket Layer (SSL) encryption to ensure the highest security for credit card and personal details submitted to us over the Internet.



The site will have to use a security certificate issued by VeriSign.

Scalability and extendibility 

Due to the changing nature of the world and rapid advancement in Informat Information ion Technology echnology and Communi Communicat cation, ion, the system system will will always always tends to change to accommodate the new requirements.

7

Project Proposal




Also the project sponsors might later decide to implement any expensive features such as using satellite technology for monitoring purposes of the delivery system such as parcel tracking system in the future.



In any such situation the system must support the system advancements and and upgr upgrad ades es with withou outt requ requir irin ing g the the syst system em to unde underg rgo o comp comple lete te changes or dump the existing system and developing a new system from scratch to meet the upgrades.



For For examp example le if new new meth method ods s discov discovere ered d to provid provide e monit monitor oring ing and and secu securi rity ty serv servic ice, e, it shou should ld be poss possib ible le to refl reflec ectt the the chan change ges s by application of logic to acquire information from that method to the system without completely changing the system.

Public confidence 

The system must win the public confidence as something that they can rely on when it comes to online purchasing.



This should ensure that the information about the books published by the system must be factual and accurate.



Also the system should handle the credit card transactions in a more secure manner by ensuing the privacy of the customers in their account numbers numbers and should should handle handle the transaction transactions s careful carefully ly & securely securely to prevent any fraud.



The proposed system will prioritize customer needs and delivery will be done according to these categories. Delivery will be categorized in to three basic classes, viz Standard, Priority and Express.



Depending on the class site will show how the delivery charges and the duration vary. vary.



Due to this since deliveries are happening on time and at the time which the books are required, better customer satisfaction can be gained and the public will be more confident about the system as well as the company.



With the advancement and complicated life styles visiting a bookshop has become really difficult.

8

Project Proposal




To facilitate these customers customers the reading corner of the online book store allow them to glance through the pages of the book before purchase the book.



Due to “Reserve Online Collect In-store” process, process, customers are able to reserve a book of interest and collect it later which will give customer satisfaction about the system.

1.3 Challenges 

It was a difficult task to convince the staff members and the management about the new technologies that are going to use in the proposed system and it was difficult to win over them.



It was difficult to get the confirmation and the approval for the cost estimation for the proposed system form the top management.



It was a time consuming task to make the staff members convince about the proposed system and make the cashiers at the counter sure about that they will not lose their jobs because of the system.



It was time consuming to collect the relevant information form the users due to the busy environment in the company.



There was resistance resistance from the cashiers for the system due to the fear of losing their jobs and had to face this challenge also during that period.

3. Analysis & Desig Design n of the Proposed System 3.1 System Transitions In this section we will be discussing the how the above mentioned functionalities of the exis existi ting ng syst system em chan change ges s with ith the the prop propos osed ed syst system em.. Als Also some some inno innova vati tive ve functionalities which are lacking in the existing system will be introduced. Sales tracking System Currently this system utilizes bar code entry and manual entry methods at the cash counter to input sales item code to the system. With the proposed system we try to introduce a new tracking device which uses radio wave based tagging system. This technology is known as RFID (Radio Frequency Identification) technology. Once the books are arrived from the suppliers they are chipped with a unique number (Item code system that is in use). With the help of a system staff can check exactly where a book is in the supply chain - whether it is been shipped, if it is in store and, if so, where exactly to find it - and so can customers. Using the system management tract the inventory details too. Along with item-level tagging it reduces the risk of books being out of stock, and the ability to track which books are flying off the shelves and which haven haven't 't moved moved in a while while.. In addit addition ion,, taking taking an inven inventor tory y will will becom become e less less of a headache and it would not be necessary to shutting up of shop for stock taking purposes. Online purchase With the current system we need to access the payment gateways provided by the each bank to proceed with a transaction. But this process waste up lot of time as the custom customer er need needs s to brows browse e throug through h many many sites sites to do a purch purchas ase. e. The The propo propose sed d system we try to eliminate this useless traverse building a payment gateways within the own domain. For this purpose system will have to store Credit card details within the customer details data store. In order to provide security and privacy different approa approach ches es are taken taken.. The The site site will will use use stand standard ard Secur Secure e Sock Socket et Layer Layer (SSL (SSL)) encryption to ensure the highest security for credit card and personal details submitted to us over the Internet. The site will have to use a security certificate issued by VeriSign eriSign (Normal (Normally ly High High Grade Grade encrypt encryption ion of 256bit 256bit recomme recommende nded). d). And the site recognizes the concerns of customer regarding privacy of information. All information submi submitte tted d by custo custome mers rs will will be secu securel rely y stored stored,, and and is not acces accessi sible ble to other other unauthorized parties.

Project Proposal


Product delivery is a dependable process of the Purchase functionality. The existing system provides provides a Shipping Shipping facility to purchased purchased items. But as the team has identified all the delivery will be done at a basic flat rate. But this does not prioritized the need of the customer. Therefore with the proposed system will be modifying and introduce a method of prioritizing customer need. Delivery will be categorized in to three basic classes, viz Standard, viz Standard, Priority and Express. Depending on the class site will show how the delivery charges and the duration vary. Online Reservation This is a new functionality added to the system. With this customers are able to reserve a book of interest and collect it later. This will be addressed as “Reserve Online Collect In-store” process. As an exception customers will be able to purchase the reserved book online without going to the In-store. The reservation can be handled only only by regis register tered ed user user and and custo custome merr will will be asked asked to agree agree with with certai certain n set set of conditions before reserving the book of interest. Customer Forum Existi Existing ng syste system m provid provides es a metho method d of conta contacti cting ng the the compa company ny throug through h virtue virtue of making enquiries. But it does not help to convey news about the bookshop to the customer, such exhibitions, book stalls, book sales etc. Therefore team suggested a custom customer er foru forum m to publi publish sh new new updat updates es abou aboutt the the book booksho shop p as an advert advertis ising ing strategy. Data Mining Since Since the book booksho shop p is maint maintain aining ing sales sales deta details ils we can can use use differ differen entt statis statistic tical al analysis methods methods to analyze the trend of sales. With this bookshop can publish about the “Best Seller” books weekly or monthly as the company needs. This permits the readers to know about the latest trends in the society and go for them. Also with data mining we can identify the probable book/books a regular customer is going going to buy. buy. So with with that that data data in hand hand we can analy analyze ze who are are the the prob probab able le customers of a new release and let them know via Newsletters. Readers Corner This is an essential component of an online book store. With the advancement and complica complicated ted life styles visiting visiting a booksh bookshop op has become become really really difficu difficult. lt. But most readers have the thirst to read. To facilitate these customers modern society came up with online book stores. But most of them are reluctant to purchase online without glancing through the pages. But with readers corners this facility will be fulfilled. There site can publish publish critics, critics, reviews reviews etc made made regardin regarding g books. books. So the customer customer can evaluate the quality of the book reading these articles and purchase good books.

4. Implementation Plan This chapter contains the implementation plan of the proposed Online Book Store system. Supporting Supporting documents documents (i.e. (i.e. Gantt Gantt charts, charts, budget budget estimations estimations etc.) etc.) for the implementation plan are also included. Chapter introduces and focuses mainly on testing strategies employed for unit, system, interface and integration testing carried out in latter stages of the development life cycle.

4.1 Tools and Technologies Implementation Language: Microsoft Visual ASP.NET ASP.NET 2.0 The system design is done using MS ASP.NET language. It is recommended that the Visual Studio.NET 2005 to be used as the environment in developing the system. Host operating System: Microsoft Windows Server 2003/.NET Sinc Since e we decid decided ed to do the imple impleme menta ntatio tion n usin using g .NET .NET enviro environm nment ent it is necessary that the system runs under Microsoft Windows environment. Hence the recommended operating system to have the server application is Widows 2003 server. For the client application OS requirements are either any Windows 2000, XP, XP, 2003 or Vista. Database System: Microsoft SQL Server 2005 Enterprise Edition Microsoft SQL server is preference over other DBMS as it is more compatible with the development environment than any other DMBS available. Other software required: Rational Rose Enterprise edition – This is used as the UML modeling tool in the designing phase of the project. Microsoft Office Word – This This appli applicat cation ion was was used used as the the docu documen mentin ting g tool tool during during the the stage stages s of developing the final documentation.

Project Proposal


Test organization The Software Test Plan is designed to prescribe the scope, approach, resources, and schedule of all testing activities. In achieving this goal, it must identify the items to be tested, the features to be tested, the types of testing to be performed, the personnel responsible for testing, the resources and schedule required to complete testing, and the risks associated with the plan.

Communication & procedures This This sect sectio ion n serv serves es as a proc proced edur ural al guid guide e for for desi design gnin ing g test test case cases s and and test test documen documentati tation. on. To achieve achieve 100% 100% correct correct code, code, system system testers testers shall shall perform perform both both black box and white box testing techniques. Using these techniques will enable testers to design design test test cases cases that validate validate the correctnes correctness s of the developing developing system with respect to the requirements requirements specification. specification. The procedure shown here shall be used in conjunction with the requirements specified in this document to achieve full benefits from the testing process. When When testing testing procedure procedure conside considered red tester tester should should identify identify the require requirement ments s to be tested before actual testing is commenced. All test cases shall be derived using the current design specification. specification. Then identify which particular test(s) relevant and should be carried out for each subsystem. There after review the test data and test cases to ensure that the unit has been thoroughly verified and that the test data and test cases are adequate to verify proper operation of the unit. It is also necessary to identify the expected results for each test. Finally document document the test case configuration, test data, and expected results and perform the test(s). Succ Succes essf sful ul unit unit test testin ing g is requ requir ired ed befo before re the the unit unit is elig eligib ible le for for comp compon onen entt integration/system testing. For each unsuccessful testing it requires a Problem Trouble Repor Reportt to be gener generate ated. d. This This repo report rt shall shall descr describe ibe the the test test case, case, the probl problem em encountered, its possible cause, and the sequence of events that led to the problem. It shall be used as a basis for later technical analysis. Test documents and reports shall be submitted to the project managers and the development team should be notified about the success of their development work.

Test strategy

Project Proposal


Testing is the process of analyzing a software item to detect the differences between existing and required conditions and to evaluate the features of the software item. This is carried out in sequential manner in the following order. Unit Testing - The The unit unit test test cases cases shall shall be desi designe gned d to test test the validit validity y of the the progra program's m's corre correctn ctnes ess. s. White White box box testi testing ng will will be used used to test test the modu module les s and and procedur procedures es that that support support the modules. modules. The white white box testing technique technique ignores ignores the function of the program under test and will focus only on its code and the structure of that code. To accomplish this, a Path Testing technique shall be used. Cyclomatic complexity of the module is determined by the flow graph generated for each module. Test case designers shall generate cases that not only cause each condition to take on all all possi possible ble values values at leas leastt once, once, but but that that cause cause each each such such condit condition ion to be executed at least once. Integration Integration Testing - In this this stage stage two two units units that that have have alrea already dy been been tested tested are are combined into a component and the interface between them is tested. Integration testing identifies identifies problems that occur when units are combined. combined. By using the test plan that requires you to test each unit and ensure the viability of each before combining units, you know that any errors discovered when combining units are likely related to the interface between units. It is preferred conduct the testing according to the top-down approach. This requires the the high highes estt-le leve vell modu module les s be test test and and inte integr grat ated ed firs first. t. The The stub stubs s shou should ld be implemented provide lower level functionality. Also helps early release such as beta versions with limited functionality. System Testing - System test case design starts after the requirements specification specification is baselined. The test cases generated shall directly reflect the requirements of the functional specification. The system test case designer(s) shall design appropriate test cases to validate the correctness of the system. The black box testing techniques shall primarily be used at the system test level. This technique is a comparison of the actual output with the specified output, regardless regardless of the structure structure of the code or the code unit under test. Interface Testing – This approach helps to effectively test your UI.. It allows you to validate your application logic without the need to actually interact with the UI. The view can be tested to some degree by exposing methods on it that allow you access to the various 'widgets' that display the data. By providing access to the widgets you can query them to ensure they have been correctly updated in response to a change to the Model.

Stress Testing – Stres Stress s testi testing ng deal deals s with with the quali quality ty of the appli applicat cation ion in the environment. environment. Since this is a web based solution stress testing is crucial. Application Application is tested with overloaded server requests and determines how such situations handled by the server. Race conditions and memory leaks are often can be easily found under stress testing.

Test deliverables Most probable deliverables after the completion of testing are Test Case Design, System/Unit Test Report and Problem Trouble Report (if any). Test Case Design document shall be the complete set of test cases to be performed during testing along with implementation of test methods. This also establishes the baseline approval for all system/unit test cases before coding begins. Unit/System Test Report covers all tests cases, unit and system, performed during testing. This will be used for either system or unit tests. Copies of the System Test Report’s will be sent to QA&I and the group conducting the tests. All problems or errors found during testing shall be documented by a Problem Trouble Report . And it shall serve as a basis for further investigation investigation of the problem. Copies of the Problem Trouble Report 's will be sent to QA&I and the group conducting the tests.
