3. Introduction
◦ The proposed system specifically looks into the subject of Crime Records Management.
User can register their complaints online.
◦ The system at any point of time can provide the details of existing charge sheets and
their statuses.
◦ People can check missing persons details online using this system. The system at any
point of time can provide the details of the police station and the employees. This
system is also show most wanted person details online on the police website.

6. Description

7. Create table
◦ The CREATE TABLE statement is used to create a new table in a database.
◦ Syntax is as follows:
CREATE TABLE table_name ( column1 datatype, column2 datatype, column3 datatype, ....)

8. Create table

9. Create table

10. Create table

11. DESCRIBE COMMAND
◦ The DESCRIBE command enables you to describe objects recursively to the depth level set in
the SET DESCRIBE command. ... the type of PL/SQL object (function or procedure) the name
of the function or procedure. the type of value returned (for functions)
◦ Syntax is as follows:
◦ DESCRIBE { table-Name | view-Name }

18. INSERT COMMAND
◦ The INSERT INTO statement is used to add new data to a database. INSERT INTO adds a
new record to a table. INSERT INTO can contain values for some or all of its
columns. INSERT INTO can be combined with a SELECT to insert records.
◦ Syntax is as follows:
◦ INSERT INTO table_name (column1, column2, column3, ...)
VALUES (value1, value2, value3, ...);

28. UPDATE COMMAND
◦ UPDATE command is used to update any record of data in a table. Following is its general
syntax, UPDATE table_name SET column_name = new_value WHERE some_condition; ... In
the above statement, if we do not use the WHERE clause, then our update query
will update age for all the columns of the table to 18.
◦ Syntax is as follows:
◦ UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

29. UPDATE COMMAND

30. DELETE COMMAND
◦ In the database structured query language (SQL), the DELETE statement removes one or
more records from a table. A subset may be defined for deletion using a condition, otherwise all
records are removed.
◦ Syntax is as follows:
◦ UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

31. DELETE COMMAND

32. GREATER THAN OPERATOR(>)
◦ Greater than ( > ) — returns true if the value on the left is greater than the value on the right,
otherwise it returns false . Less than or equal to ( <= ) — returns true if the value on the left is
less than or equal to the value on the right, otherwise it returns false .
◦ Syntax is as follows
◦ SELECT * FROM table_name WHERE condition;

33. GREATER THAN OPERATOR(>)

34. JOINS
INNER JOIN
◦ The INNER JOIN selects all rows from both participating tables as long as there is a match
between the columns. An SQL INNER JOIN is same as JOIN clause, combining rows from two
or more tables. ... For example, retrieving all rows where the student identification number is
the same for both the students and courses tables
◦ Syntax is as follows
◦ SELECT column_name(s)
FROM table1
INNER JOIN table2
ON table1.column_name = table2.column_name;

47. INDEX:
◦ An index is an on-disk structure associated with a table or view that speeds retrieval of rows
from the table or view. ... These keys are stored in a structure (B-tree) that enables SQL Server
to find the row or rows associated with the key values quickly and efficiently.
◦ Syntax is as follows
◦ CREATE INDEX index_name
ON table_name (column1, column2, ...);

48. INDEX:

49. LEFT JOIN
◦ The LEFT JOIN command returns all rows from the left table, and the matching rows from the
right table. The result is NULL from the right side, if there is no match.
◦ Syntax is as follows
◦ SELECT column_name(s)
FROM table1
LEFT JOIN table2
ON table1.column_name = table2.column_name;

59. outer join
◦ When performing an inner join, rows from either table that are unmatched in the other table are
not returned. In an outer join, unmatched rows in one or both tables can be returned. There are
a few types of outer joins: LEFT JOIN returns only unmatched rows from the left table.
◦ Syntax is as follows
◦ SELECT column_name(s)
FROM table1
FULL OUTER JOIN table2
ON table1.column_name = table2.column_name
WHERE condition;

71. CURSOR and LOOP
IMPLICIT CURSOR
◦ Implicit cursors are automatically created by Oracle whenever an SQL statement is
executed, when there is no explicit cursor for the statement. ... Whenever a DML
statement (INSERT, UPDATE and DELETE) is issued, an implicit cursor is
associated with this statement.
◦ Syntax is as follows
◦ DECLARE
◦ TOTAL_Complaints INT;
◦ BEGIN
◦ UPDATE FIR SET FIR_ID=&FIR_ID
◦ WHERE FIR_ID=1;
◦ TOTAL_Complaints:=SQL%ROWCOUNT;
◦ IF SQL%FOUND THEN
◦ DBMS_OUTPUT.PUT_LINE('NUMBER OF ROWS UPDATED' || TOTAL_Complaints);
◦ ELSE
◦ DBMS_OUTPUT.PUT_LINE('FAIL');
◦ END IF;
◦ END;
◦ /

72. CURSOR and LOOP
IMPLICIT CURSOR

73. EXPLICIT CURSOR AND LOOP
◦ An explicit cursor is a named pointer to a private SQL area that stores information for
processing a specific query or DML statement—typically, one that returns or affects multiple
rows. You can use an explicit cursor to retrieve the rows of a result set one at a time.
◦ Syntax is as follows
◦ DECLARE variables;
◦ records; create a cursor;
◦ BEGIN OPEN cursor;
◦ FETCH cursor; process the records;
◦ CLOSE cursor; END;

74. EXPLICIT CURSOR AND LOOP

75. Date and time :
◦ In SQL, datetime date data type is used for values that contain both date and time. Microsoft
defines it as a date combined with a time of day with fractional seconds that is based on a 24-
hour clock. ... SQL retrieves and displays DATETIME values in 'YYYY-MM-DD hh: mm: ss'
format.
◦ Syntax is as follows
◦ SELECT * FROM Orders WHERE OrderDate='2008-11-11'

76. Date and time :

77. EXCEPTION HANDLING
◦ Exception handling ensures that the flow of the program doesn't break when
an exception occurs. For example, if a program has bunch of statements and
an exception occurs mid way after executing certain statements then the statements after
the exception will not execute and the program will terminate abruptly.
◦ Syntax is as follows
◦ DECLARE <declarations section> BEGIN <executable command(s)> EXCEPTION
<exception handling goes here > WHEN exception1 THEN exception1-handling-
statements

78. EXCEPTION HANDLING

79. View
Views can join and simplify multiple tables into a single virtual table. Views can act as
aggregated tables, where the database engine aggregates data (sum, average, etc.) and
presents the calculated results as part of the data. Views can hide the complexity of data.
◦ Syntax is as follows
CREATE VIEW view_name AS
SELECT column1, column2, ...
FROM table_name
WHERE condition;

80. View

81. Trigger
◦ A trigger is a special type of stored procedure that automatically runs when an event occurs in
the database server. DML triggers run when a user tries to modify data through a data
manipulation language (DML) event. ... SQL Server lets you create multiple triggers for any
specific statement.
◦ Syntax is as follows
◦ CREATE [OR REPLACE ] TRIGGER trigger_name.{BEFORE | AFTER | INSTEAD OF }{INSERT
[OR] | UPDATE [OR] | DELETE}[OF col_name]ON table_name.

83. FUTURE SCOPE:
The scope of the project includes that what all future enhancement scan be done in this system to make it
more feasible to us:
 Databases for different products range and storage can be provided.
 Multilingual support can be provided so that it can be understandable by the person of
any language.
 More graphics can be added to make it more user friendly and understandable.
 Manage & backup versions of documents online.

84. CONCLUSION:
 Now-a-days everything is getting computerized.
 Manual work usually consumes a lot of time and is error prone.
 To make complaining easy and manage crime records this application is very helpful.
 The “Crime Management System” is a web based website for online complaining and computerized
management of crime records.
 Here in this website a person who wishes to file a complaint or report an incident must register before log in and
once the admin authenticates the user that he or she can login into the website and file a complaint.
This complaint will be received by police and police can send a message regarding status of the complaint to the
user who filed.
