Definition:-

The Marriage Bureau system is meant for maintaining information of bride and bridegrooms. It makes a matching between brides and bridegrooms depending on their requirements. Enquiry facility is provided where ever required.

Platform minimum requirements

Hardware/Software

Hardware / Software element Specification /version

Hardware Processor Intel core to duo

RAM 1 GB

Hard Disk 100 GB

Software OS Windows XP

Java and Net beans IDE

2. Analysis & Design

2.1 Analysis classes

The software requirements specifications are analyzed and the following classes are identified

Class BrideintbrideId;String brideName;String brideAddress;intbrideMobileNo;intbrideAge;intbrideHeight;intbrideWeight;String brideQualification;String brideJobPosition;intrbgminheight;intrbgmaxheight;intrbgminweight;intrbgmaxweight;String rbgJobPosition;intrbgminsalary;intrbgmaxsalary;void displayRecord();

Various functions in each module are identified and are shown below.

Function Identification - module wise

Module Number Module Name Function

Serial Function Title

1.

Management of Brides information

1. To create brides information file2. To update brides information file3. To search brides information file4. To generate Reports

The following narrates the functional description in detail.

1. Management of Brides Information1 Management of Brides

information1.1 To create brides information file Here we will be creating brides information

with details like brides name,brides age, drides salary along with requirements of bridegroom. Here each and every record has to be entered manually through keyboard, where it asks the user to save how many records he need to enter. After entering those records through proper format those details which user gives can be saved

1.2 To update brides information In this module we will be able to update the details of bride through the records which are present in the form of age, name, salary, educational qualification. Here we can search those details either through age. If any extra details have to be added we will update those details in place of previous details.

1.3 To search brides information file In this module we will be able to search the

details of bride which are present in files, where details will be in the form of age, name, salary, educational qualification. Here we can search those details either through age. Here in this module formatter file takes control of all the things for searching the complete details of bride

1.4 To generate reports Here in generating reports we will be able to display all the details of records of brides with details in the form of files.

2 Management of Bridegrooms information

2.1 To create bridegrooms information file

Here we will be creating bridegroomss information with details like bridegrromss name, bridegrooms age, bridegrooms salary along with brides requirements. Here each and every record has to be entered manually through keyboard, where it asks the user to save how many records he need to enter. After entering those records through proper format those details which user gives can be saved

2.2 To update bridegrooms information

In this module we will be able to update the details of bridegroom through the records which are present in the form of age, name, salary, educational qualification. Here we can search those details either through age. If any extra details have to be added we will update those details in place of previous details.

2.3 To search bridegrooms information file

In this module we will be able to search the details of bride which are present in files, where we can search those details either through age. Here in this module formatter file takes control of all the things for searching the complete details of bride

2.4 To generate reports Here in generating reports we will be able to display all the details of records of bridegrooms with details in the form of files.

3 Matching3.1 To make matching BridesId is read, the brides file is open and the

Brides record is displayed. Bridegrooms file is opened and each record is investigated for the match with brides requirement. If match is found record is displayed.

3.2 To Intimate to bride Here in this module we need to maintain bridegroom requirement details which have to be mentioned to be bride. For matching, where there will be so many records of bridegroom details for

perfect matching3.3 To intimate to bridegroom Here in this module we need to maintain bride

requirement details which have to be mentioned to be bride. For matching, where there will be so many records of bride details for perfect matching

3.4 To enquire on conformation for selection

After short listing all the records of both brides and bridegrooms, where enquie will be done based on conformation whether that bride details were matched to bridegroom details and bridegroom details were matched to bride details or not

4 Main Module4.1 To display System Banner After all modules were integrated through files

we display System Banner as MARRIAGE BUREAU

4.2 To process menu Here Processing Menu can be done through switch case statement with all the modules that are present in the file

4.3 Initializations Here Initializations can be done to methods, variables as well as objects which are present in classes

4.4 To provide Security To provide Security we need to add user name and password with login credentials where user will able to access his details with valid login credentials so that he can be able to create files, search a file and display record of that file, where as in admin module the admin also has to access his entire details with username and password where he can be able to do modifications for files that are present in user module.

2.3 File Design

This system uses two files. The names of the files and the record layout are given below

File Name 1

Bride.txt

Field No. Field name Field Type Field Size1 brideId; Integer 8 digits2 brideName String 10 characters3 brideAddress String 10 characters4 brideMobileNo Integer 10 digits5 brieAge Integer 2 digits6 brideHeight Integer 2 digits7 brideWeight Integer 2 digits8 brideQualification String 10 characters9 brideJobPosition String 10 characters10 Rbgminheight Integer 2 digits11 Rbgmaxheight Integer 2 digits12 Rbgminweight Integer 2 digits13 Rbgmaxweight Integer 2 digits14 rbgJobPosition String 10 characters15 Rbgminsalary Integer 8 digits16 Rbgmaxsalary Integer 8 digits

File Name 2

BrideGroom.txt

Field No Field name Field Type Field Size1 bgId; Integer 8 digits2 bgName String 10 characters3 bgAddress String 10 characters4 bgMobileNo Integer 10 digits5 bgAge Integer 2 digits6 bgHeight Integer 2 digits7 brideWeight Integer 2 digits8 bgQualification String 10 characters9 bgobPosition String 10 characters10 Rbrideminheight Integer 2 digits

11 Rbridemaxheight Integer 2 digits12 Rbrideminweight Integer 2 digits13 Rbridemaxweight Integer 2 digits14 rbrideJobPosition String 10 characters15 Rbrideminsalary Integer 8 digits16 Rbridemaxsalary Integer 8 digits

2.4 Input Design

For creating a file, the system takes all inputs from keyboard and the writes to file.

A sample input dialog for creating brides information file is shown below

How many records?2Enter Brides Id:12345678Enter Brides Name: Krishna.....

For selecting different functions of the system it displays a menu and reads the choice of user from keyboard.

Menu1. Create Brides File 2. Add more records to Brides file3. Search by Bride Id;4. Generate Report;5. Quit

The System also takes input from files(The file design was shown earlier)

2.5 Out Put Design

The output of the system (including reports) is displayed on the console in a formatted way. The output may also go to a file(file design already explained).

Following is the formatted output for displaying list of brides

List of brides 1. brideId.: 12345678

brideName: krishnabrideAge: 29 2. brideId.: 12345670

brideName: gopalbrideAge: 32End of List

1. For searching details of bride with its brideId the search report will be displayed as follows

Search by brideId enter brideId: 12345670 1. brideId.: 12345670

brideName: gopalbrideAge: 322. Enter brideId:12345678

brideId.: 12345678brideName: krishnabrideAge: 29

the information of brides and bridegrooms. It makes a matching between brides

and bridegrooms depending on their requirements. The system provides facility to

insertion of records. Search facility is provided to search for the information in the

file. The system makes a matching between bride’s and bridegroom’s requirement.

The system provides security through login and password .Here, only matching of

bridegroom to bride is arranged. We can also can match bride to bridegroom.
