  • Title: Internet Banking


    Now a Days Internet banking has become very popular as bank user or client can easily access his/her account from anywhere in the world Some features of this project are: -Create Account -Update Account -Change Pin -Transaction Details -Customer Information Looking for an online comprehensive solution to manage Internet banking. This will be accessible to all customers who have a valid User Id and Password. This system provides the following facilities: Balance Enquiry Funds Transfer to another account in the same bank Request for cheque book/change of address/stop payment of cheques Viewing Monthly and annual statements. User of the System A. Team members (Customers) B. Industrialists, Entrepreneur,Organisations academicians etc. C. Administrators Functional Requirements i. Customer must have a valid User Id and password to login to the system ii. If a wrong password is given thrice in succession, that account will be locked and the customer will not be able to use it. When an invalid password is entered a warning is given to the user that his account is going to get locked. iii. After the valid user logs in he is shown the list of accounts he has with the bank. iv. On selecting the desired account he is taken to a page which shows the present balance in that particular account number v. User can request details of the last number of transactions he has performed. A report can also be taken of this vi. User can make a funds transfer to another account in the same bank. User is provided with a transaction password which is different from the login password. vii. User can transfer funds from his account to any other account with this bank. If the transaction is successful a notification should appear to the customer, in case it is unsuccessful, a proper message should be given to the customer as to why it failed. viii. User can request for cheque book/change of address/stop payment of cheques ix. User can view his monthly as well as annual statements. He can also take print out of the same. Non-Functional Requirements i. Secure access of confidential data . SSL can be used. ii. 24 X 7 availability iii. Better component design to get better performance at peak time iv. Flexible service based architecture will be highly desirable for future extension Optional Features Java based client for Administrator Customizable color scheme or skins The E-Banking is an application that has been developed for a well-established regional bank operating primarily in south India. The bank has several branches in key cities and towns in the north. In the world of this competitive environment and technological development, the bank has been totally computerized in the last 3 years, and to increase its customer base has started planning, for a concept called as e-banking; with this concept the bank wants to move very nearer to the customers and increase its basic operational strategies. Through E-Banking the bank wants to introduce the core concept of IT based Enabled Services (ITES). The E-Banking services are executed only upon the customer, and these e-banking services would fully integrate with the core banking solution that is already in usage. The major idea is to provide a series of services to the customer through the internet, and make the customer feel flexible in calling out simple tasks faster instead of making visit to the bank every time. The e-banking service is open only to savings bank. Customers and not for current account holders. The customer is privileged to use most of the system only as a viewing phase, the only online transactions the customer can do are chequebook requisition and fund transfer among his personal accounts.


    What is JAVA ?

    Java is an entire programming language resembling C or C++. It takes a sophisticated programmer to create Java code. And it requires a sophisticated programmer to maintain it. With Java, you can create complete applications. Or you can attach a small group of instructions, a Java "applet" that improves your basic HTML. A Java Applet can also cause text to change color when you roll over it. A game, a calendar, a scrolling text banner can all be created with Java Applets. There are sometimes compatibility problems between Java and various browsers, operating systems or computers, and if not written correctly, it can be slow to load. Java is a powerful programming language with excellent security, but you need to be aware of the tradeoffs.


    What is JSP ?

    Short for Java Server Page. A server-side technology, Java Server Pages are an extension to the Java servlet technology that was developed by Sun. JSPs have dynamic scripting capability that works in tandem with HTML code, separating the page logic from the static elements -- the actual design and display of the page -- to help make the HTML more functional(i.e. dynamic database queries). A JSP is translated into Java servlet before being run, and it processes HTTP requests and generates responses like any servlet. However, JSP technology provides a more convenient way to code a servlet. Translation occurs the first time the application is run. A JSP translator is triggered by the .jsp file name extension in a URL. JSPs are fully interoperable with servlets. You can include output from a servlet or forward the output to a servlet, and a servlet can include output from a JSP or forward output to a JSP. JSPs are not restricted to any specific platform or server. It was orignially created as an alternative to Microsoft's ASPs (Active Server Pages). Recently, however, Microsoft has countered JSP technology with its own ASP.NET, part of the .NET initiative.


    What is JavaScript ?

    When new technologies start, they sometimes acquire names that will be confusing in the future. That's the case with JavaScript. JavaScript is not 'Java'. JavaScript is a simple programming language that was developed by Netscape that writes commands to your browser when the HTML page is loaded. Note: you can have compatibility issues with Java Script, especially in newer versions of Browsers.


    What is Java:

     Java is a simple, distributed object oriented programming language which provides the security, High performance, robustness. Java is a portable and Architectural neutral language which can be Interpreted. Java is multithreaded and Dynamic language.


    About Java:

     Java is a Programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java Platform. The language derives much of its Syntax from c and C++ but has a simpler object Model and fewer low-level facilities. Java applications are typically compiled to bytecode(class file) that can run on any Java Virtual machine (JVM) regardless of computer architecture.


    Why Software Developers Choose Java: 

    Java with its versatilty, efficiency, and portability, Java has become invaluable to developers by enabling them to: • Write software on one platform and run it on virtually any other platform • Create programs to run within a Web browser and Web services • Develop server-side applications for online forums, stores, polls, HTML forms processing, and more • Combine applications or services using the Java language to create highly customized applications or services • Write powerful and efficient applications for mobile phones, remote processors, low-cost consumer products, and practically any other device with a digital heartbeat. 


    Goals in creation of Java:

    There were five primary goals in the creation of the Java language 1. It should
    be "simple, object oriented". 2. It should be "robust and secure". 3. It should be "architecture neutral and portable". 4. It should execute with "high performance". 5. It should be "interpreted, threaded, and dynamic".


    Architecture of Java:

    Java's architecture arises out of four distinct but interrelated technologies: • The Java programming language • The Java class file format • The Java Application Programming Interface • The Java virtual machine When you write and run a Java program, you are tapping the power of these four technologies. You express the program in source files written in the Java programming language, compile the source to Java class files, and run the class files on a Java virtual machine. When you write your program, you access system resources (such as I/O, for example) by calling methods in the classes that implement the Java Application Programming Interface, or Java API. As your program runs, it fulfills your program's Java API calls by invoking methods in class files that implement the Java API.


    The Java Virtual Machine 

     At the heart of Java's network-orientation is the Java virtual machine, which supports all three prongs of Java's network-oriented architecture: platform independence, security, and network-mobility. A Java virtual machine's main job is to load class files and execute the bytecodes they contain. As you can see in Figure 1-3, the Java virtual machine contains a class loader, which loads class files from both the program and the Java API. Only those class files from the Java API that are actually needed by a running program are loaded into the virtual machine. The bytecodes are executed in an execution engine.

     Coding standard 

     Java suggests set of coding standard to follow while writing java program. Coding standard helps author as well as others to better understand program. It reduce amount of debugging time considerably. Basically coding standard suggests how to name class, methods variables of different scope, package etc.


     Writing a Java program 


     In the Java programming language, all source code is first written in plain text files ending with the .java extension. Those source files are then compiled into .class files by the javac compiler. A .class file does not contain code that is native to your processor; it instead contains bytecodes — the machine language of the Java Virtual Machine1 (Java VM). The java launcher tool then runs your application with an instance of the Java Virtual Machine.
