The following narrates the functional description in detail.
1. Management of Brides Information
1 Management of Brides
information
1.1 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,
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,
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 Matching
3.1 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 matching
3.3 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 Module
4.1 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 recordlayout are
given below
File Name
1
Bride.txt
Field No. Field name Field Type Field Size
1 brideId; Integer 8 digits
2 brideName String 10 characters
3 brideAddress String 10 characters
4 brideMobileNo Integer 10 digits
5 brieAge Integer 2 digits
6 brideHeight Integer 2 digits
7 brideWeight Integer 2 digits
8 brideQualification String 10 characters
9 brideJobPosition String 10 characters
10 Rbgminheight Integer 2 digits
11 Rbgmaxheight Integer 2 digits
12 Rbgminweight Integer 2 digits
13 Rbgmaxweight Integer 2 digits
14 rbgJobPosition String 10 characters
15 Rbgminsalary Integer 8 digits
16 Rbgmaxsalary Integer 8 digits
File Name
2
BrideGroom.txt
Field No Field name Field Type Field Size
1 bgId; Integer 8 digits
2 bgName String 10 characters
3 bgAddress String 10 characters
4 bgMobileNo Integer 10 digits
5 bgAge Integer 2 digits
6 bgHeight Integer 2 digits
7 brideWeight Integer 2 digits
8 bgQualification String 10 characters
9 bgobPosition String 10 characters
10 Rbrideminheight Integer 2 digits

11 Rbridemaxheight Integer 2 digits
12 Rbrideminweight Integer 2 digits
13 Rbridemaxweight Integer 2 digits
14 rbrideJobPosition String 10 characters
15 Rbrideminsalary Integer 8 digits
16 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?
2
Enter Brides Id:12345678
Enter Brides Name: Krishna
.
.
.
.
.
For selecting different functions of the system it displays a menu and reads the
choice of user from keyboard.
Menu
1. Create Brides File
2. Add more records to Brides file
3. 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: 32
End 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: 32
2. Enter brideId:12345678
brideId.: 12345678
brideName: krishnabrideAge: 29

CONLUSION:
The Marriage Bureau system is maintained
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.
