    • MODULES OF SDMS New RecordsEdit Records SDMS Student Details
    • DESCRIPTION OF THE SYSTEMThe project is titled "SCHOOL Data Management System". This package oncedeveloped will help the school/institute to manage various details pertaining to itsstudents. This will help accounts department in maintaining the details related tothe fees & basic details like their security deposits, conveyance and etc, it willalso help management or we can say administration department in maintainingstudents basic details as well as keeping a check on fees details. This package isbasically developed for the authorities of the school/institute to make their taskeasier or we can say this package automate their tasks like maintaining studentspersonal details, marinating cash details, printing of receipts. This package helpsthe administrative & accounts department in maintaining the students personal &fees related details.The details of the system are as follows:It is basically a Database management package for the authorities of theschool/institute like management, accounts & administrative department. All thedetails of the students & the daily work of various departments are managed bythe package i.e. Personal details, Cash details, Fees status, printing of receipts etc.The package is by the name of School/institute Data Management Package.Package helps the various departments in maintaining & manipulating the data.School/institute data are divided into Personal information, Cash details, fee status& etc it helps in manipulating the divided parts of the data.Modules of the system: Personal Information / Student details Fees Details Fees Status Report GenerationPersonal Information / Student details:This module helps in managing thepersonal information of the students like their Name, Address, Phone no., Roll no& etc. The package helps in adding the personal records, editing the records, 2
    • retrieval of records, report generation & etc.Fees Details:This module helps in managing the fees details of the student liketheir tuition fees, security, late fees & etc. The basic purpose behind thedevelopment of this module is printing of receipts of the fees paid by the students.Fee Status:This module helps in managing the fees records of the students likehow many have paid their fees & how many are yet to pay their fees & what is thereceipt no. of the student who have paid their fees. Basically this modulegenerates the list of all the students who have paid their fees & it also generates alist for those students who haven‟t paid their fees.Report Generation:This module is basically all about report generation; in thispackage quite a few reports are generated which are embedded in the form likestudent details, cash details & etc.Functions performed by the package:This package helps in managing the student information like their Name, Roll no.annual charges or we can say personal details, it also manages their fees details,receipt generation & etc. The package helps in adding the official records, editingthe records, retrieval of records, report generation & etc. Security:The package provides security by the help of Username & Password, the package has been designed to be used on a stand-alone system & by specific user hence there was no need for multi-user approach. Maintenance & Manipulation:The package helps in maintaining & manipulating information pertaining to students & daily activities of the school/institute authorities for e.g. maintaining students personal details, fee structures, maintaining cash details, fees status & etc. Search:This facility help in searching the required record from the database, package has the provision of searching of the record through admission no. which is Primary Key & through the name & class of the student. 3
    • Help: This facility provides for help for the usage of the system. It provides help to the novice regarding the usage of the package.The School/institute Data management Package provides the user of the Systemwith a window like interface. The Front end of the package is developed in VBi.e. Visual Basics, Back end is made in MS Access NEED OF THE SYSTEMThe Package is developed to help the department maintaining the student details,earlier the records where maintained manually, with the help of this package theconcerned departments will be able to improve the productivity, reduce the time,cost factors associated with the system. The automation of the system will helpthe organization in proper maintenance of the record, less manpower, less man-days, less cost, proper & accurate functioning.The basic need for the package was to automate the whole procedure ofmaintaining of student details, earlier it was all done manually. By developing thispackage lot of burden was removed from the department, which was maintainingstudents details. It improved the efficiency, reduced the cost, and reduced the timeneed to do the work manually. With the help of this package the past details of thestudents can assessed and reports can be generated on this details.In brief we can say this system was required to automate the processing ofstudents details, which was done manually before the development of thepackage. Earlier all the information / data pertaining to the students wasmaintained manually or we can say it was on paper, hence it created a problem forthe organization/ school, how to manage it properly. With the help of this systemthe organization/school is able to maintain the data properly & accurately.Why System was build…? Earlier, data pertaining to students was maintained manually. Manual system was not efficient. 4
    • Cost of maintaining data manually was bigger or huge. Large manpower was required. The procedure was error prone, it was not accurate. Manual system was not suited for electronic exchange of data.Solution…?The solution for all this problem was to automate the system, automation of thestudents data maintenance would reduce the manpower, man days will result inaccurate data & above all increase the efficiency of the concerned department. FEASIBILITY STUDYFeasibility is the test of the system it helps in deciding whether it is viable to gothrough the project or not. Feasibility study studies the system & tells whether todevelop the system or not. In lay mans terms it can be described as the test of thesystem & if the system passes in the test then it is viable to develop the projectotherwise not or we can say feasibility study check‟s whether project is feasible ornot.Feasibility has four solid dimensions: 1. Technology 2. Finance 3. Time 4. ResourcesThe feasibility of the system “ SCHOOL Data Management System ” is viewedwith the help of these four dimensions.Technology: This system uses one of the simplest technologies in use, for the developmentpurpose it uses simple to use & easily available technology. This system is basedon windows like interface, which is very easy to use. The package is beendeveloped for the department, which is not very familiar with software hencetechnology used, must be easily understandable, because of which windows like 5
    • interface has been chosen. The technology used in this project is VB i.e. VisualBasics 6.0, M S Access & DAO controls. Visual Basic helps in providingwindows like environment. This system uses menu-based approach in whichevery thing is given with the help of menus.Finance:This dimension measures the system in respect to money or we can say funds.This dimension checks whether its viable to spend the required amount on thesystem or it will be a waste. There is no problem of finance in this project becauseit uses simple technology, which is very easy to install. This system is beendeveloped for a standalone computer hence for this system hardware requirementis very low. For this system to be developed & installed properly we require veryeasily available technologies & very basic hardware and all these requirementsdoesn‟t cost much.Time:This particular dimension measures the systems worth in respect to time, which isone of the most important factors to be considered. In this project time factor isvery important this system is scheduled to be installed in one months time. Thissystem is not very big & hence can be completed within the time period itrequires approx. 30 man-days of work. Time is a crucial factor to be considered &we can say this system can be developed within the required time period.Resources:This dimension takes into count the recourses required to develop the system. Forthis particular system the resources required are quite nominal which can befulfilled, the resources required for this system are basic hardware, an operatingwhich is compatible with VB.With the help of all these dimension we can measure the feasibility of the system& can decide whether to go forward with the project or not. By take in count the 6
    • dimension & their role in this particular system we can say this system is feasiblefrom all these dimension point of view & it is viable to go through the project. 7
    • SCOPE OF THE SYSTEMScope of the system measures the scope of the project, which is going to bedeveloped. Answering following aspects can answer the project scope: 1. Context 2. Information objective 3. Function & Performance 4. InterfacesThe system “SCHOOL data management system” is a data management ofstudents. All the details of the students are managed with the help of this packagei.e. their Personal information, fees information & their report generation, withthe help of this package the organization can maintain & manipulate studentsdata. This package has the provision for adding new records, editing old records,viewing the database, searching facility, report generation, help i.e. how to use thepackage & etc. Scope of the system can be measured with the help of thedimensions.Context:This project is related to management of students data and the daily activities ofthe authorities with the help of this package the user of this package, which is thedepartment i.e. administrative will be able to maintain the data through thecomputer which will help in increasing he efficiency, accuracy of the departmentas well as help in electronic inter change of the data. Administrative departmentcan use this package to check for the details of the students, whether they havepaid their fees amount or whether it is due to them, through which receipt no. itwas paid they can study the past records analyze the trends.Information objective:Basically this is related to the Inputs & Outputs to the system. In other way we 8
    • can say it is related to the inputs required by the system & outputs generated bythe system.This package is basically data management package, in which the inputs given bythe user is itself the output of system it performs few calculation like the totalcash received from the students. We can say it is data management package, itprovides the user with front end which is very easy to use. 1. Inputs: The input to the system is username & password for the system security, their Personal details like Name, Address, Phone number, admission details, roll no for data management, their fees details like admission fees, tuition, computer fee & etc . 2. Outputs: The output for this system is the maintained records, personal details, fees details, fee status & report generated. The outputs of the system are the records that were added in the database as well as the reports that are generated with the help of he data in the database.Function & Performance:This dimension measures the scope of the system with the help of functions &performance of the system. The basic function performed by the system is of datamanagement & report generation.The system performs various functions like: 1. Security: The first function of the system is to provide security from unauthorized access to the data, which is provided with the help of user name & password at the beginning of the package. This system is been developed for a single user hence no rights are employed or we can say administrator is only the user. 2. Data maintenance: The most important function of the system is to maintain student data, the data is maintained with the help of different menus like adding, editing, 9
    • viewing, searching & etc. There are different kinds of data in the system like personal information, fees information & cash details with the help of the front end data is managed.3. Report generation: The last function of the system is to generate reports of the data like student details report, cash report, fee status report & etc. With the help of this report the data can be electronically exchanged as well as the reviewing of policies can be done with the help of reports. These are some of the basic function performed by the system “Student Data Management”.4. Interfaces: Interfaces are the link between the user and the system, basically we can say interfaces are the objects through which user of the system interacts with the system. This system has different interfaces through which user interacts with the system they are:1. Login interface: This is the first interface in which user is required to enter the username & password if the password is correct then access is granted otherwise not. User has got three attempts to enter the correct password; if he is not able to enter the correct password in three attempts then the system is exited.2. Data maintenance: This is the most important interface in the system in which the user interacts with the system to store the data or to retrieve the data from the database, this interface has got many sub parts like addition of records, editing of records, searching of records & etc.3. Reports: This interface is the output for the system in which the user receives the results or output, which is required in the form of reports like cash details, student details & fee status. 10
    • OBJECTIVESThe following are the main objectives of the project titled "Student datamanagement ":The package provides the means of security, which makes sure that only theconcerned modules and screens are accessible to the particular department afterverifying ones validity and all other modules and screens remains disable. Thepackage is meant to maintain and provide complete details about students such aspersonal details, their fees details and cash details.The basic objective of the system is to manage the student‟s data efficiently &accurately. It provides the user of the system with personal details of the studentstheir name, address, phone & etc, it provides the user with fees as well as cashdetails of the students, how much they have paid, what is the status of the fees i.e.how many have paid fees & how many are yet to pay the fees. It also provides theuser with details of cash like conveyance details.“ Student data management ” package is a Management & Information project,which has these objectives:Student data management will be highly user friendly, management informationsystem that will not help only Accounts, Management & Administrative system togather, communicate, computerize but also help to act on critical informationmuch faster and in a better manner. The solution envisages linking of differentdepartments to streamline the flow of data and timely availability of informationat both the ends. Further, it also aids in generating, maintaining user definableQueries, Reports. Salient Features of the application will be as defines below: 1. Owner of data to be the owner of the database 2. Capture of information at the source of generation 3. Sharing of data 4. Minimizing duplicate work 5. Reducing inconsistency by eliminating multiple databases of the same data 6. Consolidation of data at all levels 11
    • Outlined objectives of the system:User friendliness:The package developed is easy to learn and understand. Even a new user can usethe system effectively, without any difficulty. The help and user manuals areprovided to solve the further queries of the users. With the help of the usermanuals the user can get the full details of the functionality of the system.User satisfaction:The package is such that it stands up to the users expectations. The system issuccessful in generating the reports of the task status and details of the student.The package is currently being successfully run in the organization.Response time:The response time for all the operations is less. All the report generations and thelisting tasks are performed in significant time. The queries used are so as toreduce the execution time of query processing.Error handling:Responses to users errors and undesired situation have been taken care of toensure that the system operates without halting. Proper error handling codes areput with the codes.Security and robustness:The package is able to avoid or tackle disastrous action. It allows only theauthentic user to access the software as it is protected by the user name and thepassword. All the administrative tasks are allowed to the project leader only so theillegal intervention is not possible. 12
    • Modularity:The package has relatively independent and single function parts that are puttogether to make complete system. Thus as a result of this modular approach thesystem, in spite of being robust is not cumbersome. It also contributes for the fastexecution of the system.Maintainability:The system is able to decrease the time and effort for program maintenance. Thefull details of the projects being undertaken, and the task status corresponding toeach student is stored carefully and the reports are generated as per therequirement OPERATING ENVIORNMENTThe system is developed in Visual Basics 6.0 / M S Access and run underwindows 95/98 & upper versions.Visual Basics:Visual basics is event driven programming language, which is used to developfront end for the application. This is called event driven because every action ofthe user is an event & the application is driven with the help of these events,which are programmed with the help of Visual basics. In Visual basics there areforms, Controls, reports & many more things to provide the user withoverwhelming experience of user friendliness. Visual basics is a programminglanguage for windows environment & provides the user with windows likeinterface.M.S. Access:Access is a Relational Database Management System (RDBMS) that you can useto store and manipulate large amounts of information. Because its tools are user- 13
    • friendly and because it is a powerful development environment, Access is equallyappropriate for novices and MIS professionals.Beginners can use Access to: 1. Store and manage various types of inventories. 2. Log information such as auto repairs for cars, doctor visits, etc. 3. Create contact management databases that can track contacts, but phone calls, meetings, and any other interactions with contacts.Developers can use Access to: 1. Create applications that manage survey results. 2. Manage front ends for enterprise-wide database such as SQL server. 3. Establish help-desk applications.Access is an object-oriented program; that is, everything in Access is an object,including the application itself. Each object has properties that define how it looksand performs. The uses of Access are limited only by the needs of an organizationand the imagination of the user or developer. 14
    • HARDWARE & SOFTWARE REQUIREMENTHardware Requirements:Hardware requirement are the basic need of the system or the package, which isbeen developed and will be deployed upon the system, which should have thesebasic components or fulfill these basic hardware needs of these package.The following hardware is recommended for the user.Microprocessor: PIII500 MHz.Memory: 128 MB SDRAM DIHMCache Memory: 512 KBL2Upgrade ability: Processor, RAM and HDD UpgradeableHDD: 9.1 GB Wide ultra SCSI-3 HDDFloppy Drive: 24x CD ROM Drive (IDE)Keyboard: 104 Keys Enhanced KeyboardMouse: 2 Button Scroll MouseGraphics: 1024x768, 256 colors non-interlaced on PCL Local BusMonitor: 15” SGA Color monitorSoftware Requirements: Software requirement are the basic software needsof the system or the package to work properly & efficiently.Operating System: Windows-98 & upper versionsRDBMS: MS Access 97For editing the code of the package:Application program: Visual Basics 6.0 SYSTEM REQUIREMENTS SPECIFICATIONThe function and performance allocated to software as part of system engineeringare refined by establishing a complete information description, a detailedfunctional and behavioral description, an indication of performance requirements 16
    • and design constraints, appropriate validation criteria, and other data pertinent torequirements. The outlines of system requirement specification are:Introduction:This System Requirement Specifications Document forms the basis for the designand development of the ”Student data management”. The purpose of thisdocument is to define all the processes involved in the function of Student datamanagement. The requirements of the software relating to the functionality,interfaces, logical database requirements and various other aspects of the softwareare also explicitly defined. The SRS document will also act as the basis forunderstanding between the end-user and the designer/developer.Information Description:The development of this system assists in the maintenance of the information andto fulfill the complete software requirements of the package.Functional Description:A processing narrative is provided for each function, design constraints are statedand justified, performance characteristics are stated and diagram is included.Validation and Criteria:For successful implementation of the system we should define the performancebounds, and expected software response. At the time of creating new entry,system performs different types of validations like user can not overwrite theexisting information, it asks the user, this information already exist and also manyfeature. 17
    • DFD‟SDFD:It stands for Data flow diagram it is a diagrammatic representation of the dataobjects of the system. Basically DFD is a way to show the how the data isprocessed in the system, it shows how data moves at different stages in thesystem. DFD is a graphical representation that depicts information flow & thetransformations that are applied as data moves from input to output. It is also usedto represent a system or software at any level of abstraction it can be partitionedinto levels that represent increasing information flow & functional details.Data Flow Diagram serves two purposes: 1. To provide annunciation of how data are transformed as they move through the system. 2. To depict the functions that transforms the data flow.DFDs are a excellent mechanism for communicating with the customer duringrequirement analysis and are widely used for the representation of external andtop-level internal design specification. In the latter situations, DFDs are quitevaluable for subsystem, files and data links. The DFD methodology is quiteeffective, especially when the required design is unclear. In the process, manylevels of DFDs are created depending upon the level of details needed.The Level 0 DFD is also called Context Level DFD. It depicts the overview of theentire system. The major external entities, a single process and the output storesconstitute the level-0 DFD. Though this diagram does not depict the system indetail, it represents the overall inputs, process and output of the entire system at avery high level.The Level 0 DFD is now expended into a level 1 model. It should be noted thatinformation flow continuity is maintained between level 0 and level 1. Theprocess represents at DFD level 1 further refined into lower levels. This further 18
    • refinement is continued until an easily implement able program component isreached. LEVEL „0‟ DFD OF “STUDENT DATA MANAGEMENT” User name & Password Storing Modifying And Retrieving Students Data Details of Students 19
    • LEVEL „1‟ DFD OF “STUDENTDATA MANAGEMENT” Access Denied Attempt Verification Granted Exit Of For The Data Three Times Access Granted NewAddition Menu MDI / Main Cash Details of Menu Form Report i.e. fee New Shown detail,Records Report security Edit Menu Student Editing Detail of Report Records Printing Receipt s Printing of Fee Cancellation Receipts & Reprinting of Receipts Storing, Manipulation & Retrieval of Student Data 20
    • These are the two DFD‟S i.e. 0 level & 1 level of “Student Data Management ”package the 1 level dfd can be further refined to represent more detailed or lowerlevel of information. DFD‟s are also known as flow graph or bubble chart. ER-DIAGRAMEntity – Relationship Diagram: Depicts relationships between data objects. Theobject-relationship pair can be represented graphically using the Entity-Relationship Diagram. A set of primary components is identified for the ERD:data objects, attributes, relationships, and various type indicators. The primarypurpose of the ERD is to represent data objects and their relationships.Data Objects, Attributes, and RelationshipsThe data model consists of three interrelated pieces of information: the dataobject, the attributes that describe the data object, and the relationships thatconnect data objects to one other.Data Objects:A data object is a representation of almost any composite information that mustbe understood by software. By composite information, we mean something thathas a number of different properties or attributes. A data object encapsulates dataonly there is no reference within a data object to operations that act on the data.The data object description incorporates the data object and all of its attributes.Data objects are related to one another.Attributes: Attributes define the properties of a data object and take on one ofthree different characteristics. They can be used to name an instance of the dataobject, describe the instance, or make reference to another instance in anothertable. The set of attribute that is appropriate for a given data object is determinedthrough an understanding of the problem context. One or more of the attributes 21
    • must be defined, as an identifier that is identifier attribute becomes a “Key” whenwe want to find an instance of the data object.Relationships:Data object are connected to one another in a variety of different ways. We candefine a set of object-relationships pairs that define the relevant relationships.Object-relationship pairs are bi-directional. Different data objects and theirattributes are described in data dictionary and their relationships between thesedata objects are given in ER diagram of next section.Cardinality and ModalityCardinality: The data model must be capable of representing the number ofoccurrences of objects in a given relationship. The cardinality of an object-relationship pair are: 1. One-to-one (1:1): An occurrence of object „A‟ can relate to one and only one occurrence of object „B‟ and an occurrence of „B‟ can relate to only one occurrence of „A‟. 2. One-to-many (1:N): One occurrence of object „A‟ can relate to one or many occurrences of object „B‟ but an occurrence of „B‟ can relate to only one occurrence of „A‟. 3. Many-to-many (M: N): An occurrence of object „A‟ can relate to one or more occurrences of „B‟, while an occurrence of „B‟ can relate to or more occurrences of „A‟.Cardinality defines “the maximum number of object relationships that canparticipate in a relationship”.Modality:The modality of a relationship is zero if there is no explicit need for therelationship to occur or the relationship is optional. The modality is 1 if anoccurrence of the relationship is mandatory. 22

    • IMPLEMENTATION STRATEGIESA crucial phase in the system life cycle of the successful implementation of thenew system design. Implementation simply means conveying a new systemdesign into operation. This involves creating computer-compatible files, trainingthe operating staff and installing hardware, terminals and telecommunicationnetworks before the system is up and running. A critical factor in conversion isnot disrupting the functioning of the organization.In system implementation, user training is crucial for minimizing resistance tochange and giving the new system a chance to prove its worth. Training aids, suchas user friendly, manuals, a data dictionary, job performance aids thatcommunicate information about the new system and “help” screens provide theuser with a good start on the new system.There are three types of implementation: 1. Implementation of a computer system to replace a manual system: The problems encounter are converting files, training users, creating accurate files and verifying printouts for integrity. 2. Implementing of a new computer system to replace an existing one: This is usually a difficult conversion. If not properly planned there can be many problems. Some large computer system has taken as long as a year to convert. 3. Implementation of a modified application to replace an existing one using the same computer: This type of conversion is relatively easy to handle, provided there are no major changes in the files.Conversion means changing from one system to another. The objective is to putthe tested system into operation while holding costs, risks, and personnel irritationto a minimum. It involves –Creating computer compatible filesTraining the operating staffInstalling terminals and hardware. A critical aspect of conversion is not disruptingthe function of the organization.Several procedures and documents are unique to the conversion phase. 48
    • Conversion begins with a review of the project plant, the system testdocumentation, and the implementation plan. The parties involved are the user,the project team, programmers, and operatorsThe conversion portion of the implementation plan is finalized and approved. 1. Files are converted. 2. Parallel processing between the existing and the new systems is initiated. 3. Parallel processing between the existing and the new systems is initiated. 4. Results of computer runs and operation for the new system are logged on a special form 5. Assuming no problems, parallel processing is discontinued. Implementation results are documented for reference.Conversion is completed. Plans for the post-implementation review are prepared.Following the review, the new system is officially operational.File conversion involves capturing data and creating a computer file from existingfiles.Copying the “old” files intact for the new system is the prime concern duringconversion. The programs that copy the files should produce identical files to testprograms on both systems. At the outset, a decision is made to determine whichfiles need copying. Personnel files must be kept of course, but an accountreceivable file with many activities might not need copy in. Instead, new customeraccounts might be put on the new system, while running out the old accounts onthe old system.Once it is determined that a particular file should be transferred, the next step is tospecify the data to be converted, current file, year-end files, and son on. Then filesto be copied must be identified by name, the programmer who will do thecopying, and the methods by which the accuracy of the copying will be verified.A file-comparison program is best used for this purpose. 49
    • TESTINGTesting:Testing is the process of executing the programs with the intention of finding outerrors. During testing, the program to be tested is executed with a set of test casesand the output of the programs for the test case is evaluated to determine if theprogram is performing as it is expected to be.As the software is created and added to the developing system, testing isperformed to ensure that it is working correctly and efficiently. Testing isgenerally focused on two areas, internal efficiency and external effectiveness. Thegoal of external effectiveness testing is to verify that the software is functioningaccording to system design, and that it is performing all the required functions.The goal of internal testing is to make sure that the computer code is efficient,standardized, and well documented. Testing can be a labor-intensive process dueto its iterative nature.Test Plan:We divided the testing procedure into these levels: - Unit Testing. Integration Testing. Validation Testing. System Testing.These different levels of testing attempt to detect different types of faults. Therelations of faults introduced in different levels of testing are as shown below 51
    • Requirements System testing Clients Needs Validation Testing Design Integration Testing Code Unit Testing Levels of TestingUnit Testing:The first level of testing is called unit testing. In this, different modules are testedagainst the specifications produced during design for the modules. Unit testing isessential for verification of the code produced during the coding phase, and thegoal is set to test the internal logic of the modules.Integration Testing:The next level of testing is often called the integration testing. In this many testedmodules are combined into subsystems, which are then tested. The goal here is tosee if the modules can be integrated properly, the emphasis being on testinginterfaces between modules. This testing activity can be considered as testingdesign and hence the emphasis on testing interactions.Validation Testing:During validation testing, the system is used experimentally to ensure that thesoftware does not fail, i.e. will run according to its specifications and in the wayusers accepts, special test data input for processing, and the results examined. A 52
    • limited number of users may be allowed to use the system so analysts can seewhether they try to use it in unforeseen ways.System validation checks the quality of the software in both simulated and liveenvironments. First the software goes through a phase in which error and failuresbased on simulated user requirements are verified and studied, called alphatesting. The modified software is then subjected to phase two in the actual user‟ssite or a live environment, called beta testing.System Testing:A series of different tests whose function is to verify that all system elements havebeen properly integrated and perform allocated functions.Testing of “Student Data Management ”:In case of Student data management package, I performed unit testing to eachindividual function to see that whether they are working properly or not. Weexamined each loop, which occurred in the functions for every possible value.Integration testing was also being performed by combining the different modulesand the results were examined. Some steps are taken for testing: 1. Proper validation is done or not. 2. Exceptions are handled or not. 3. Correct menus open or not. 4. Records are properly updated & saved or not. 5. Is system able to detect Intruder? 53
    • Samples Of Unit Testing: Few samples of unit testing are explained with the help of screenoutputs. Unit testing is basically testing the modules with the dummy data. If Admission no is not in the database message will be If search button is prompted. No record pressed before entering found. the name it will ask for the field. 54
    • USER MANUALAbout the System:It is basically a Database management package for the authorities ofschool/institute that maintains student‟s data. All the details of student aremanaged by the package i.e. Personal details, Fees details, Reports & etc. Thepackage is by the name of Student Data Management Package. Package helps thevarious departments in maintaining & manipulating the data. Student data aredivided into Personal information, Fees Details, Receipt printing & etc it helps inmanipulating the divided parts of the data. This system is for the departmentmaintaining student records.Platform:This system is platform independent, it will work on any platform. Operatingsystem recommended for this system is Window‟s 98 & upper versions.How to use it?Student Data Management package has a very user friendly environment & it‟sinterfaces are similar to windows, so it will not take time for the user to getacquainted with the system, there are few things that should be kept in mindbefore using the system those points are explained with the help of screen outputs.This Package is developed for stand-alone system, hence for logging on thesystem user must know the Username & Password. After choosing from themenus the specific options few things has to be kept in mind which are explainedbelow. 55
    • Addition of records: For adding record For filling up first fill up the another students form after that data click new click on ok then enter details .Follow this pattern in other form of adding records as well as in other parts of thesystem. ame procedure should be applied through the package. This package has asimilar environment to windows, so it is easy to work with. 56
    • Editing Records: For editing therecords enter the id Samethen click on search procedureafter that make the should be changes & then applied for save. delete & result System should be exited through close button 57
    • RESULTS & CONCLUSIONSTopics covered:- Limitations- Biblography 58
    • LIMITATIONS OF THE SYSTEMLimitations of the system and future development areas:Limitation of any system is difference between the required system & thedeveloped system: - 1. It is developed for only stand-alone PC. 2. This system is quite easy to use this is not its limitation but its restrictive features are its limitation. 3. The back end used in the system is M S Access, which is not an RDBMS. 4. The system does not support multiple users. 5. There are few things, which should be kept in mind while using the system. 59
