INTRODUCTION AND OBJECTIVE OF THE PROJECTIntroductionStudent Profile Maintenance Module For Placement & HR contains profile of students. The project created by using core java. The main components used are : Core Java as language JDBC (Java Database Connectivity) Java Swings Microsoft Access for creating tablesThe project will ask user name, user password to login for both students and administrator. Student has facility to maintain and update his profile and can also change his password. He/She cant assess any other students profile. Administrator has right to create and delete profile of student. He can assesses profile of any student and update it as well as change his password. Administrator can also change his own login password and username.ObjectiveThe main objective behind the development of this project is to create software with the following features: Highly user-friendly Enterprise independent Cross-platform Easy-to-use Tested system to track unnoticed error Data entry restricted to valid domains to avoid errorsJAVAThe entire component has been developed using Java technology. Java has been chosen as the platform because of its feature rich nature. The Java Platform provides robust end-to-end solutions for networked applications as well as a trusted standard for embedded applications. So Java was a natural choice for development process.Characteristics of JavaObject Oriented: Java is object oriented to the truest sense of the word. Everything in Java is represented as objects. Variables and methods both are encapsulated in objects. Java is the purest object-oriented language.Robust: Java is a very robust language owing to the following features. Excellent exception handling facilities. Memory management relief for the user. User does not have to worry about allocation and deallocation of memory. Strict compile-time and runtime checks for data types.Portable and Architecture-neutral (Platform Independent):Java is portable and platform independent so much that they satisfy write once;run anywhere, anytime, forever. This feature is implemented in the following ways: Compiler generates machine independent byte-code instructions which can be run on any machine supportingJava Virtual Machine. Size of primitive data type is machine independent.Multithreaded: Programs can do many things simultaneously using different threads. Provides a solution for multiprocess synchronization. Allows the creation of networked and interactive programs.Distributed: Open access to remote objects by the use of RMI(Remote Method Invocation). Brings a level of abstraction to client/server programming.Secure: Security is achieved by confining a java program to the java execution environment and not allowing access to other parts of the user computer. Absence of pointers provide memory related security as encroachment of memory is avoided Proper measures for prevention of viral infection and malicious intent.Dynamic and Extensible: Facilitates linking in of new classes, objects and methods. Supports native methods (methods written in other languages like C ,C++). Programs carry with them a substantial amount of runtime type information that is used to verify and resolve accesses to objects at run-time.High Performance: Just-In-Time (JIT) compilers are used to convert byte-code into native machine code resulting in very high performance. These JIT compilers can be used on a real time, piece by piece demand basis to perform on-the-fly compilation of byte-code into native-code.Compilation and InterpretationJava programs are implemented as a two-stage system.Compilation: Source code to byte-code and not machine instructions.Interpretation: Byte-code to machine code (for any system that supports using JVM)Thus cross-platform programs can be written. JAVA SWINGS"Swing" refers to the new library of GUI controls (buttons, sliders, checkboxes, etc.) that replaces the somewhat weak and inflexible AWT controls.The Swing classes eliminate Java's biggest weakness: its relatively primitive user interface toolkit. Java Swing helps you to take full advantage of the Swing classes, providing detailed descriptions of every class and interface in the key Swing packages. It shows you how to use all of the new components, allowing you to build state-of-the-art user interfaces and giving you the context you need to understand what you're doing. It's more than documentation;Java Swinghelps you develop code quickly and effectively.1. Main New Features Lightweight. Not built on native window-system windows. Much bigger set of built-in controls.: Trees, image buttons, tabbed panes, sliders, toolbars, color choosers, tables, text areas to display HTML or RTF, etc. Much more customizable.Can change border, text alignment, or add image to almost any control. Can customize how minor features are drawn. Can separate internal representation from visual appearance. "Pluggable" look and feel. Can change look and feel at runtime, or design own look and feel. Many miscellaneous new features. Double-buffering built in, tool tips, dock able tool bars, keyboard accelerators, custom cursors, etc.2. Components are named JXxx.E.g. JFrame, JPanel, JApplet, JDialog, JButton, etc.J ComponentThe J Component class is the root of the Visual component class hierarchy in JFC. All Swing components are implemented as subclass of J components class, which inherits from the Container class. Swing component inherit the following functionality from J Componenta). Borders- Using the setBorder() method, you can specify the border that a component displays around its edges. You can specify that component have extra space around its edges using an EmptyBorder instance.b). Double Buffering- It can improve the appearance of frequently changing components. Now you do not have to write the double buffering code because Swing provides it for you. By default Swing components are double buffered.c). Tool Tips- By specifying a string with the setToolTipNext() method, you can provide help to users of a components. When the cursor pauses over the components, the specified string is displayed in small window near the component.d). Look and Feel- Subject to the security restriction, you can choose the look and feel used by all Swing components by invoking the UIManager.setLookAndFeel() method.3. There is an almost-equivalent Swing component for most AWT components.4. Instead of adding components directly to frames or applets, we can use the content pane. Add to content pane via getContentPane().add Replace content pane via setContentPane5. Model-View-Controller architecture let us change the internal data representation for lists, trees, tables, etc.6. Swing was in the com.sun.java.swing package in beta releases of 1.2. Switched to javax.swing in 1.2 final.7. Default "look and feel" is a Java-specific one. Need special call to get native look Default called "Java look & feel"8. Mixing AWT and Swing is doomed.AWT components are always on top, and z-ordering problems catch you in many unexpected ways. Stick with the AWT or move completely to Swing.JDBCThe JDBC is a set of the database access classes. The very term JDBC stands for Java Database Connectivity. It was developed by Java Soft. JDBC technology is an API (Application Program Interface) that allows virtual access to any tabular data source from the Java programming language by means of some connecting software called Drivers. It provides cross-DBMS connectivity to a wide range of SQL databases. JDBC defines a set of interfaces to enable developers to access data independently of the actual database product used to store the data. JDBC allow Java applets, Servlets, and application to access data in famous database management systems.It also provides access to other tabular data sources, such as spreadsheets or flat files. The JDBC API allows developers to take advantage of the Java platform's "Write Once, Run Anywhere" capabilities for industrial strength, cross-platform applications that require access to enterprise data. With a JDBC technology-enabled driver, a developer can easily connect all corporate data even in a heterogeneous environment. The JDBC API is the industry standard for database-independent connectivity between the Java programming language and a wide range of databases. The JDBC API makes it possible to do three things: Establish a connection with a database or access any tabular data source Send SQL statements Process the resultsSteps in using JDBC1. Create a Connection type of object (A) denoting a connection to the database.2. Create a Statement type of object (B) using the A.3. Use B to execute either update the database or send a query request.4. The result of the query operation in step 3 is a Result Set type of object(C)5. C is actually a small table (D) consisting of the result of the query.6. D can be handled according to the user needs7. Close C,B and ASQL SQL stands for Structured Query Language, better known as sequel. It is used for:1. querying a database by editing the SQL statements.2. querying a database within a program3. defining data organization.4. administrating data5. accessing multiple data servers6. managing transaction.JDBC ARCHITECTUREThe JDBC API contains two major sets of interfaces: JDBC API for application writers Lower-level JDBC driver API for driver writersJDBC drivers are divided into four types or levels. Each type defines a JDBC driver implementation with increasingly higher levels of platform independence, performance, and deployment administration. The four types are: Type 1: JDBC-ODBC Bridge Type 2: Native-API/partly Java driver Type 3: Net-protocol/all-Java driver Type 4: Native-protocol/all-Java driverType 1: JDBC-ODBC BridgeThe type 1 driver, JDBC-ODBC Bridge, translates all JDBC calls into ODBC (Open Database Connectivity) calls and sends them to the ODBC driver. As such, the ODBC driver, as well as, in many cases, the client database code, must be present on the client machine. Figure 1 shows a typical JDBC-ODBC Bridge environment.JAVA APPLICATIONJDBC DRIVER MANAGERJDBC/ODBCBRIDGEODBCDRIVERDATABASEFigure 1. Type 1: JDBC-ODBC Bridge

Pros: The JDBC-ODBC Bridge allows access to almost any database, since the database's ODBC drivers are already available. Type 1 drivers may be useful for those companies that have an ODBC driver already installed on client machines.Cons: The performance is degraded since the JDBC call goes through the bridge to the ODBC driver, then to the native database connectivity interface. The result comes back through the reverse process. Considering the performance issue, type 1 drivers may not be suitable for large-scale applications.The ODBC driver and native connectivity interface must already be installed on the client machine. Thus any advantage of using Java applets in an intranet environment is lost, since the deployment problems of traditional applications remain. We have used JDBC-ODBC Bridge Type DriversREQUIREMENT ANALYSISFor analysis of requirement for the software to be developed first of all we set some guidelines and following those only we start analyzing in specific manner. The whole analysis work is divided in following activities:1. Problem Recognition2. Problem Evaluation and Solution Synthesis3. Modeling4. Creation Of Specification5. Review Of AnalysisProblem Recognition: We deeply assess the use and technical feasibility of the software to be developed We meet the users and select all the persons who will be helping in specifying requirements and then understand their organizational bias. Then we define the technical environment into which the product or system was to be placed of the software. Then we identify the Domain Constraints i.e the specific environment needed for effective application. This helps us to limit the functionality and performance of the software. We choose the team meeting with users to elect one or more requirement.Problem Evaluation and Solution Synthesis: We observe all the data objects to be used by us and according to requirement. Then according to the objects and functions we have analyzed we now decided the flow of the information as per the requirements Then we define the software functions which we must make to obtain the flow and results with the data and achieve the projects objective. Now we analyze the behavior of the software in context with the software after defining all above tasks so as to fix the performance. Now we planned and analyzed the way which we must apply to have the asked type of user interface as per demand of the functions and data flow we have decided to use. Now we decide the requirements keeping in mind the system specifications. Also keeping in mind the information which we have to input to and output from the system so as to achieve the proper connectivity and transparency regarding the data.Modeling: The modeling is performed by designing the DFDs for all the possible states of the software.Creation Of Specification:The specifications were made as per the design analysis. It was confirmed that: Is each requirement consistent with the product design? Is the requirement really necessary or just the add-on feature? Does any requirement conflicts with the other requirements? Is the requirement achievable in the specific technical environment? Review Of Requirements:In this stage we just review all the requirements listed by us and see arent we missing any one during our calculation and logic plannings. Here also we follow some basic guidelines: Here we study the function and performance of computer based system and the constraints. The final statement of requirement was examined by the original sources. All the requirements related with a particular are listed in dependency traceability. The requirements which were testable were marked with tests to exercise the requirements later. It was made clear that the requirement is traceable to overall system/product objectives. The requirements associated with the system performance, behavior, and operational characteristics were clearly stated. FEASIBILITY ANALYSISIntroduction of Feasibility Study:Many feasibility studies are disillusions for both user and analysts. First , the study often presupposed that when the feasibility of a document is being prepared, the analyst is in a position to evaluate solution. Second, most studies tend to overlook the confusion inherent in the system development. If the feasibility study is to serve as a decision document, it must answer three questions1. Is there a new and better way to do the job that will benefit the user?2. What are the costs and saving of the alternative(s)?3. What is recommended?The most successful system projects are not necessarily the biggest or most visible in a business but rather those that truly meet user expectations. Most projects fail because of inflated expectation than for any other reason.Feasibility Study:As not every imagination is feasible, not even in software, evanescent a sit may appear to outsiders. On the contrary, software feasibility has five solid dimensions:Technical FeasibilityIs the prepared technology practical? Technical feasibility centers around the existing computer system and to what extent it can support the proposed addition. But in this case since earlier all the work was manual and there was no existing system, so the system proposed is technically feasible. Also, the new system should be brought according to the specification of the product being designed.Operational FeasibilityIs the problem worth solving? Will the solution to problem work? The answer to the above question is yes. As the problem is worth solving because the manual work is very inefficient and from the statement of the problem gives us a clue that there is a solution to the problem and there are pretty good chances that the solution will work.Economic FeasibilityIt is used to measure the cost effectiveness of a project which is commonly known as cost-benefit analysis. The project is also economically feasible as the only requirement involving expenses are related to the cost of buying a new system and a printer for the hard copies. And the maintenance involved in this is only the maintenance of the computer and that does not cost much. So according to the requirements the system is economically fit.Legal FeasibilityLegal feasibility means that the software developed is legal; it is not violating any governmental constraints and it is following all the legal laws. Since the project is developed for use within a particular college only, it can by no mean violate any legal laws.Therefore, it is said to be legally feasible too.Behavioral FeasibilityBehavioral feasibility is an estimate of how strong reaction the user staff is likely to have towards the development of a computer system. Since this project lightens the burden of the manual work in the cell, so the end users of the software will always be encouraging towards the use of computer. Also, no jobs are going to be replaced in this case.DESIGN ANALYSISDesigning is the most important part of the software development lifecycle. It requires careful planning and logical thinking on the part of the software designer. Designing the software means how the various parts of the software are going to meet the user requirement and goals. It should be done with utmost care as a simple mistake or miscalculation at this stage can result in errors which can be compounded manifold as the development process moves up the development hierarchy. This compounded error can result in low performance, more processing time, and more coding and extra load.System Design attempts to accomplish the following: Improve productivity of analysts and programmers. Improve documentation and subsequent maintenance and enhancements. Cut down drastically on cost over runs and delays. Improved communication among the users ,analysts, designers and programmers Standardize the approach to analysis and design Simplify design by segmentationThe java.sql PACKAGEThe implementation of JDBC is made through the java.sql package. This package contain all the JDBC classes and method that allows the developers to create databases application .The topmost class in the class hierarchy of JDBC classes is the DriverManager, which keeps the driver information, state information and more. When each driver is loaded, it is registered with the DriverManager. Whenever a connection is made, the DriverManager selects the driver depending on JDBC URL.The JDBC URL is a string that is used by the drivers to locate and access databases. The syntax of a JDBC URL is:jdbc::The defines the type of drive and provides the network-encoded name.CREATING DATA SOURCE NAME (DSN)Before starting the program using JDBC ODBC bridge drivers, create tables in Microsoft Access according to requirement. Let its name be emp and fields ename, design, hiredate, deptno.Now lets create a DSN by name empdb, which we will use in the program based on JDBC ODBC drivers. The steps to create DSN are given below1. Goto Control panel, click on Administrative Tool and then click on ODBC Data Sources as shown in figure 2 and 3.

It also provides access to other tabular data sources such as spreadsheets or flat files.This class serves four things: Establish a connection with a database or access any tabular data source. Send SQL statements. Process the results.In this case, A Connection type of object conn denoting a connection to the database is created. A Statement type of object stmt is created using the Connection object i.e. conn. Use stmt to execute either update the database or send a query request.This class has four functions:1) It connects to the database by openConnection() method.public Connection openConnection(){ Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); Connection conn=DriverManager.getConnection("jdbc:odbc:stu_prof_maintainance"); System.out.println("********connection opened*********"); return conn;} 2) It executes query :-public ResultSet execSQLCommand (String qry, Connection conn){ ResultSet rs = null; Statement stmt = null; stmt = conn.createStatement(); rs = stmt.execute Query(qry); return rs; }3 ) It updates query :-public int updatetable (String qry, Connection conn){ ResultSet rs = null; Statement stmt = null; stmt = conn.createStatement(); rs = stmt.executeUpdate(qry); return retvalue; }4) It closes the Connection :-public void closeConnection(Connection conn){ conn.close(); stmt.close();}BACK END The back end, which is the tool used for the designing of the database required in the application was chosen to be Microsoft Access, which provides powerful tools for managing and analyzing. The various tables used are-1. adminfo- This table contain administrator name and administrator password which are used to login through login window by administrator.

Figure 16 table containing administrator name and password2. personaldata - This table personal information of student profile like name, password and e-mail, percentage.

Figure 17. Table containing information about student profileQUALITY ASSURANCEThere are basically three levels of Quality Assurance, namely, testing, validation and certification. Each of these is described below:1 TestingThe purpose of system testing is to identify and correct errors in the system and also to judge if the system meets the requirements of the user or not. There are three levels of system testing. They are as follows:Unit Testing:This type of testing focuses on the verification of the smallest unit of software design namely the module. Using the procedural description as a guide, important control paths are tested to uncover the errors within the boundary of a module. Unit testing is normally white-box oriented, and the steps can be conducted in parallel for multiple modules. In this project the sub-modules have been individually tested.Following checks were made: Given set of data was taken as input to the module and the output was observed Logic and boundary conditions for input and output were also checked Interfaces between two modules were also checked Runtime Exceptions were thrown which were detected and rectified by taking the Stack Trace Also all the possible situation were anticipated with the help of the user to conduct thorough tests of the system.Integration Testing:In this type of testing the main aim is to take the unit tested modules and build a program structure which can be directed and dictated by the design.This includes: Top-down Testing Bottom-up testing Regression TestingThe last of the above was particularly important in this project which helped in ensuring changes without introducing unintended behavior in addition.System Testing:This type of testing consists of a series of tests whose primary purpose is to fully exercise the computer based system all work to verify that system elements have been properly integrated and that they perform specified functions.When the individual program modules are working, we combined the modules into single working system. This integration was planned and conducted in such a way that whenever an error occurs we get an idea about the source of it.The entire system was viewed as a hierarchy of modules. We began with the module at the highest level of design and worked down. Then the next modules to be tested were those that called previously tested modules.Functional Testing:Once it was certain that information passed between modules according to the design description, the system was tested to assure whether the functions describing the requirement specification were performed by the system.Acceptance Testing:When the functional test completes. The user gets involved to make sure that the system works according to the users expectation.2 ValidationSystem validation checks the quality of the software in both simulated and live environments. It has two phases.Alpha Testing:In this the software goes through a phase in which errors and failures based on simulated user requirements are verified and studied. The modified software is then subjected to Beta Testing.Beta Testing:This is testing the software in the actual users site or a live environment .The system is used regularly with live transaction .After a scheduled time, failures and errors are documented and final correction and enhancements are made before the package is released for use.Checks & Constraints:There are many validations and checks to control input and navigational errors. These are as follows:Input validations are done for the following cases:Essential fieldsCharacter numeric InputChoosing from certain range of valuesNon-repetition of primary key valuesNo-input or wrong input3 CertificationThe third level of quality assurance is to certify that the program or software package is correct and conforms to standards.IMPLEMENTATION1 Hardware Requirements:Pentium III / IV Processor256 MB RAM or higherPrinterMouseKeyboard2 Software Requirements:-Microsoft AccessJdk1.3 or higher versionNotepad3 Installation:The component comprises of several Java Classes, some image files (Java Archive).To start using this component,- we will save the java files in bin folder of jdk1.5.- Provide necessary database connection details and information about the URLs.- Install Microsoft-Access in system.- And save the various tables used in the project. UNIQUE FEATURES OF THE COMPONENTPlatform independentThe component is mostly developed using Java Technology which is essentially Platform Independent. The fact that on compilation java files get converted into machine independent byte-code makes it a cross-platform technology. The byte code can then be run on any machine having the JVM (Java virtual Machine).It becomes very easy to reuse the component .Thus it is a completely pluggable component which can be plugged into any other related system with very little modification. Users can perform their operations asynchronously as relational database tables are used at the back end, which support data integrity and uniformityConcurrent access anomaly problem is also taken care of.Highly flexible and customizableThis component can work with any database connection as prior to installation; users have to provide their database configurationWhen the application is first started, the user is asked to provide all the information regarding the kind of database, username, password etc.Enterprise IndependentThis is a Enterprise Independent Product. So the component can work for any legacy system. The users just have to provide the connection (Database) name where their tables are stored. The component can then easily customize itself so as to work in conjunction with the legacy system.Any no. of connections can be used in the component. The table can have any number of fields. Irrespective of the type and number of columns in the legacy table, the component can work successfully.The extensive use of graphical representation makes the component simple and easy to work with. The GUI is simple yet powerful. The whole hierarchy of the product is represented as a tree. The various branches of the tree represent the physical branches of the organization. The root of the tree represents the Database of the organization. The leaf nodes represent the tables present in a store -room. The layout of a particular node isrepresented graphically on a simple mouse click. The view can be either front-view, back-view or cross-sectional view. The racks, levels and the cells can be customized graphically; the results are displayed in Graphical formSECURITY OF THE SYSTEMThe following levels of security were provided in order to guard against unauthorized and malicious use, modification and destruction of data.Data Level:At each functional stage the users have access to only those portions of the data that are necessary for those functions.Application /Functionality Level:Only authorized users are allowed to get involved in this application. Moreover a particular functionality on the application is allowed to be used by only those users to whom permission has been granted to access and use it.CONCLUSIONFrom a proper analysis of the positive points and constraints on the component, it can be safely concluded that the product is a highly efficient GUI based component. This component can be easily being plugged in many other systems.Also the component is highly user friendly. Generally the search and updating in stores are done by non-technical people. So it is in the best interest of the organization to use such software which their employees can handle easily. This software comes with just that solution. Being mostly GUI based, this component can be used very easily. With very little training, users can learn the usage of the product. Also the search results are presented in numerous forms like report format, graphical format etc which makes it versatile. Again the GUI based system is certainly more eye-catching and attractive. Nowadays most of the companies are going global .So their business has also become distributed and diverse.REFRENCES1. The Complete Reference JAVA- Herbert Schildt2. JDBC OReilly3.
