7 SYSTEM REQUIREMENTS Product Definition The project is Computerization of Book Store. This project is made for any organization to manage Employee s record in an organization. The main features of this package are: Information of All the books available in Store.. Information of all the Customers Information of all the sale/purchase of Books Order Info. for those books which are not available in Store. Processing Environment: The programming language and development tools are the critical factors in the functioning of the developed system, so proper attention has to be paid while selecting these tools. Following are the minimum requirements for installation and making use of the software package:

8 Hardware requirements: Processor: Pentium RAM: 128MB HARD DISK: 40GB Printer: Any compatible printer Software requirements: JDK 1.5 SQL Server JAVA being the platform independent language to generate the user-friendly Software system is used as Front-end system and SQL Server for database system, this will facilitate user in operating the system successfully. A platform is the hardware or software environment in which a program runs. We've already mentioned some of the most popular platforms like Windows 2000/XP, Linux, Solaris, and Mac OS. Most platforms can be described as a combination of the operating system and hardware. The Java platform differs from most other platforms in that it's a software-only platform that runs on top of other hardware-based platforms. The Java platform has two components: The Java Virtual Machine (Java VM) The Java Application Programming Interface (Java API)

9 Feasibility Analysis Feasibility study describes and evaluates candidate systems and provides for the selection of the best candidate system that meets the system performance requirements. Three key considerations are involved in the feasibility analysis: 1. Economic feasibility 2. Technical 3. Behavioral 1. Economic Feasibility Economic feasibility determines the benefits and saving that are expected from the system and compare them with costs. Cost/Benefit analysis has been done on the basis of total cost of the system and direct and indirect benefits derived from the system. The total cost for the proposed system comprises of hardware costs and software costs. The main aim of economic feasibility is to check whether the system is financially affordable or not. The cost for the proposed system can be divided into two parts given below: Hardware Costs The hardware cost for the proposed system can be calculated from cost of hardware needed for the development of the proposed system. The hardware specifications for the system are given below: Personal Computer: The cost of the PC depends upon the configuration of the PC. The minimum specification assumed for the Pc is given below: Pentium IV processor 128 MB RAM 40 GB free disk space MS Windows Any compatible printer

10 Server: As the software is a client-server based application, thus an efficient server would act as the backbone of a good communication system. The minimum specifications are: Pentium IV processor 256 MB RAM 120 GB free disk space MS Windows Software Costs: the Software costs for the proposed system can be calculated from the cost of software tools needed from the development of the proposed system. The software tools needed for the development of the system are given below:- JDK 1.5 SQL Server 2. Technical Feasibility Technical Feasibility centers on the existing system and to what extent it can support the proposed system. In this part of feasibility analysis we determined the technical possibilities for the implementation of the system. Two major benefits are: Improving the performance Minimizing the cost of processing The performance category emphasis improvements in the accuracy and access to the information. It also makes easier to access the system by the authorized users. 3. Behavioral Feasibility:

11 Behavioral feasibility estimates the reaction of the User staff towards the development of the computerized system. For the successful implementation of any system, the users must be impressed that the new system is for his benefit. So, the behavioral feasibility plays a very important role in the development of new system It reveals that whether the system is acceptable by user or not. If the user does not ready to use it, then it doesn t matter how best the system is or how much effort you are putting in its development.

12 Development Schedule System development revolves around a life cycle that begins with the recognition of user needs. Following a feasibility study, the key stages of cycle are evaluation of present system, information gathering, cost/benefit analysis, detailed design and implementation of candidate system. The life cycle is not a procedure that deals with hardware and software. It is a building computerbased system to help the user to operate system effectively and manage the information successfully. The development schedule as above was followed within a fixed timeframe of six weeks. Programming Languages and Development tools: The programming language and development tools are the critical factors in the functioning of the developed system, so proper attention has to be paid while selecting these tools. Following are the minimum requirements for installation and making use of the software package: Software requirements: JAVA Developer Toolkit 1.5 SQL Server Windows/ Linux platform JAVA being the platform independent language to generate the user-friendly Software system is used as Front-end system and SQL-Server as Back-end database system, this will facilitate user in operating the system successfully.

13 About the Java Technology Java technology is both a programming language and a platform. The Java Programming Language The Java programming language is a high-level language that can be characterized by all of the following buzzwords: Simple Architecture neutral Object oriented Portable Distributed Interpreted Robust High performance Multithreaded Dynamic Secure With most programming languages, you either compile or interpret a program so that you can run it on your computer. The Java programming language is unusual in that a program is both compiled and interpreted. With the compiler, first you translate a program into an intermediate language called Java bytecodes the platform-independent codes interpreted by the interpreter on the Java platform. The interpreter parses and runs each Java bytecode instruction on the computer. Compilation happens just once; interpretation occurs each time the program is executed. The following figure illustrates how this works.

14 You can think of Java bytecodes as the machine code instructions for the Java Virtual Machine (Java VM). Every Java interpreter, whether it's a development tool or a Web browser that can run applets, is an implementation of the Java VM. Java bytecodes help make "write once, run anywhere" possible. You can compile your program into bytecodes on any platform that has a Java compiler. The bytecodes can then be run on any implementation of the Java VM. That means that as long as a computer has a Java VM, the same program written in the Java programming language can run on Windows 2000, a Solaris workstation. The Java Platform A platform is the hardware or software environment in which a program runs. We've already mentioned some of the most popular platforms like Windows 2000, Linux, Solaris, and MacOS. Most platforms can be described as a combination of the operating system and hardware. The Java platform differs from most other platforms in that it's a software-only platform that runs on top of other hardware-based platforms. The Java platform has two components: The Java Virtual Machine (Java VM)

15 The Java Application Programming Interface (Java API) You've already been introduced to the Java VM. It's the base for the Java platform and is ported onto various hardware-based platforms. The Java API is a large collection of ready-made software components that provide many useful capabilities, such as graphical user interface (GUI) widgets. The Java API is grouped into libraries of related classes and interfaces; these libraries are known as packages. The next section highlights what functionality some of the packages in the Java API provide. The following figure depicts a program that's running on the Java platform. As the figure shows, the Java API and the virtual machine insulate the program from the hardware. Native code is code that after you compile it, the compiled code runs on a specific hardware platform. As a platform-independent environment, the Java platform can be a bit slower than native code. However, smart compilers, welltuned interpreters, and just-in-time bytecode compilers can bring performance close to that of native code without threatening portability. What Can Java Technology Do? The most common types of programs written in the Java programming language are applets and applications. If you've surfed the Web, you're probably already familiar with applets. An applet is a program that adheres to certain conventions that allow it to run within a Java-enabled browser. However, the Java programming language is not just for writing cute, entertaining applets for the Web. The general-purpose, high-level Java programming language is also a powerful software platform. Using the generous API, you can write many types of programs.

16 An application is a standalone program that runs directly on the Java platform. A special kind of application known as a server serves and supports clients on a network. Examples of servers are Web servers, proxy servers, mail servers, and print servers. Another specialized program is a servlet. A servlet can almost be thought of as an applet that runs on the server side. Java Servlets are a popular choice for building interactive web applications, replacing the use of CGI scripts. Servlets are similar to applets in that they are runtime extensions of applications. Instead of working in browsers, though, servlets run within Java Web servers, configuring or tailoring the server. How does the API support all these kinds of programs? It does so with packages of software components that provides a wide range of functionality. Every full implementation of the Java platform gives you the following features: The essentials: Objects, strings, threads, numbers, input and output, data structures, system properties, date and time, and so on. Applets: The set of conventions used by applets. Networking: URLs, TCP (Transmission Control Protocol), UDP (User Datagram Protocol) sockets, and IP (Internet Protocol) addresses. Internationalization: Help for writing programs that can be localized for users worldwide. Programs can automatically adapt to specific locales and be displayed in the appropriate language. Security: Both low level and high level, including electronic signatures, public and private key management, access control, and certificates. Software components: Known as JavaBeans TM, can plug into existing component architectures.

17 Object serialization: Allows lightweight persistence and communication via Remote Method Invocation (RMI). Java Database Connectivity (JDBC TM ): Provides uniform access to a wide range of relational databases. Features of JAVA Technology Get started quickly: Although the Java programming language is a powerful object-oriented language, it's easy to learn, especially for programmers already familiar with C or C++. Write less code: Comparisons of program metrics (class counts, method counts, and so on) suggest that a program written in the Java programming language can be four times smaller than the same program in C++. Write better code: The Java programming language encourages good coding practices, and its garbage collection helps you avoid memory leaks. Its object orientation, its JavaBeans component architecture, and its wide-ranging, easily extendible API let you reuse other people's tested code and introduce fewer bugs. Develop programs more quickly: Your development time may be as much as twice as fast versus writing the same program in C++. Why? You write fewer lines of code and it is a simpler programming language than C++. Avoid platform dependencies with 100% Pure Java: You can keep your program portable by avoiding the use of libraries written in other languages. The 100% pure JAVA is a repository of historical process manuals, white papers, brochures, and similar materials online.

18 Write once, run anywhere: Because 100% Pure Java programs are compiled into machine-independent bytecodes, they run consistently on any Java platform. Distribute software more easily: You can upgrade applets easily from a central server. Applets take advantage of the feature of allowing new classes to be loaded "on the fly," without recompiling the entire program.

19 SYSTEM REQUIREMENT SPECIFICATIONS Developing Environment: The development environment is the critical factor in the functioning of the developed system, so proper attention has to be paid while selecting this environment.

43 The Construction Phase In the construction phase, the software components are built. This phase uses the output of low-level design to produce software items. During the construction phase, we divided the responsibilities among the team members. Some of them are assigned the task of designing the interface, whereas others take the job of writing the code to develop the project Team structure includes three members Reetu Reena Ritu Reetu was assigned the task of gathering required information related to the proposed project and also assigned the task of studying the existing manual system. After the completion of task various disadvantages of existing project has been studied and were kept in mind for the designing of proposed project. Reena was assigned the task of interface design and design of various databases to be used by the proposed project. After the completion of task MS ACCESS was chosen as the database required for database connectivity with JAVA. Also design of database tables was finalized. Ritu was been assigned the task of design and coding which is under progress. The various other tasks were performed collectively by the team members, which are completed up to mark.

44 The Testing Phase Testing is vital to the success of the system. System testing makes a logical assumption that if all the parts of the systems are correct, the goal will be successfully achieved. Inadequate testing leads to errors that may not appear until months later. This creates two problems: The time lag between the cause and the appearance of the problem The effect of system errors on files and records within the system A small system error can conceivably explode into a much larger problem. Effective testing early in the process translates directly into long-term cost savings from a reduced number of errors. Another reason for system testing is its utility as a user-oriented vehicle before implementation. The best program is worthless if it does not meet the user needs. Unfortunately, the user s demands are often compromised by efforts to facilitate program or design efficiency in terms of processing time or memory utilization. Often the computer technician and the user have communication barriers due to different backgrounds, interests, priorities and perhaps languages. The system tester (designer, programmer or user) who has developed some computer mastery can bridge this barrier Testing Techniques Both the Black Box testing and White Box testing techniques will be applied to the proposed project for validating the software interface and to selectively ensure that the internal working of the software is correct. The input will be validated so that the correct output is produced. The checks for consistence of the database will be properly evaluated. The procedure of the system will be

45 highly checked for the logical paths and for specific set of conditions, loops etc. 1. All the paths within module will be exercised at least once 2. The logical decision will be exercised for true or false sides 3. Whole code will be verified for the syntax errors 4. The internal data structure will be validated for data consistency 5. The graphical user interface will be checked for particular event 6. The complete application will be tested after the integration of all modules and sub modules Testing Strategies Unit testing will be applied to all the modules of the project. All the modules of the project will be tested with White Box and Black Box testing to complete unit testing. Integration Testing will also be applied to verify that all the interfaces work in co-ordination with each other. The Data Flow between different modules will be verified for the consistency of the system. The Bottom Up approach of integration will be applied to the proposed project. The alpha testing of the project has been done by the team members. The beta testing will be done by the employees of Food and Supply Department Sample Data The sample data will be prepared to ensure the proper working of the software and validate each module. After testing the proposed project with this sample data the expected results will be compared with the outputs obtained and thereafter further steps will be taken if necessary.

46 IMPLEMENTATION/CONVERSION PLAN Conversion means changing from one system to another. The objective is to put the tested system into operation while holding costs, risks and personal irritation to a minimum. It involves: 1. Installing terminals 2. Installing the appropriate hardware and software 3. Creating computer compatible files 4. Training the operating staff The conversion plan involves the following steps: Conversion begins with the review of the project plan, the system test documentation, and the implementation plan. The parties involved are the user, the project team and the operators. 1. The conversion portions of the implementation plan to be finalized and approved. 2. Files are converted 3. Parallel processing between the existing and the new systems to be initiated 4. Results of computer operations of the new system to be logged 5. Assuming no problems, parallel processing to be discontinued 6. Implementation results to be documented 7. After all these steps, conversion is complete and the new system will be now officially operational Procedure for Implementation

48 The Acceptance Phase In this phase, based on the pre-defined acceptance criteria, we have conducted acceptance testing for the project. In the case the acceptance criteria are the fulfillment of all the requirements identified during the requirement analysis phase.

49 Project Legacy Current Status of Project: The project i.e. Computerization of Book Store has been completed successfully. Various phases (Requirement Analysis, Data Design, Coding, and Testing) have been completed. The project has been underlined and is kept in vision for the correct functioning. Technical and Managerial lessons learnt We have learned to work in the team environment with different task provided to different team members. We are developing the project according to the Software Development Life Cycle. We have read the different phases of Software Development Life Cycle and also how to implement them practically. We have learnt how to make the SRS. The other things we have learnt how to create friendly interface, how to plan the work and how to work with different components. For the completion of project we had to learn the platform independent language JAVA that provides interactive user interface. The main advantage of using JAVA is platform independent which makes it to run any platform without the specified hardware or software requires. As managerial lessons we have learnt to work with patience, how to cooperate with the team members and how to work in the team.
