1. INTRODUCTION
1.1. INTRODUCTION TO PROJECT
This VJ Courier System Project Will have different modules. The login
section will have login faculty for the Admin, Employee and for the Customer
who will operate this system. While taking orders from its customers, it will
take all the details of its customers who are placing the orders and all the details
for the recipient such as its address, name and mobile number. During Payment
process system will generate a tracking id for their products. Through this
tracking id, customers or its recipient Will able to track their products.
When the consignment Will Visit to the city office of destination, Then
after take its parcels by using their Track Id When its recipient Will receive
their parcels, then this Track ld will be Updated by Employee.
When the Particular Customer Login through their Id and Password then all the
data (Previous as well as Current time) booking data to see to that particular
customer.
In modern age, as time increase, needs & requirements of the person are
also increased. They want more faculties & try to do their task quickly & within
time. But they cannot get all the things at nearest market or area, so they have to
import the things from any place in the world.
Within the country, the things can be imported through post service. But it
consumes the time & sometimes problem of damage or missing occur. Where as
in the international market, the one way is shipping But it also requires more
time.
The courier service is one of the solutions of these problems. It is used to send
some things to any person in the world within time.

VJ COURIER SERVICE'S
The VJ courier System has number of Offices, which are spread over the
country or the world. So that when person wants to send things then he has to
contact at nearest courier service branch. The VJ courier System creates the
schedule & gives internal/external services. The VJ courier service work as
destination office or source office. The source office branch receives the order
means consignments & sends it to the destination courier Offices. The VJ
courier System has certain rules according to the weight. Using the courier
service person can easily send his/her parcel to other person in the particular
destination within the time. Now days, 50% of companies of the world uses the
services of various courier company.

SERVICES:
This project deals with the ‘Courier Services’. The system is used for daily
activities such as Manage Admin, Customer, Employee as well as Courier,
Booking Courier, Update status of Courier, Offices details, View Deliver and
Return Courier. It is very difficult to do this process manually. Hence it is
recommended to computerize the process by developing the relative software as
the world is turning into information and technology; computerization becomes
necessity in all walks of life.
This project deals with the maintenance of booking details, incoming courier
details, courier non delivery details and courier return details etc; the main aim
of this project is to computerize the maintenance of courier management.

The design starts after the requirement analysis is complete and the
coding begins after the design is complete. Once the programming is completed,
the testing is done. In this model the sequence of activities performed in a
software development project are: -
Requirement Analysis
Project Planning
System design
Detail design
Coding
Unit testing
System integration & testing
Here the linear ordering of these activities is critical. End of the phase and
the output of one phase is the input of other phase. The output of each phase is
to be consistent with the overall requirement of the system. Some of the
qualities of spiral model are also incorporated like after the people concerned
with the project review completion of each of the phase the work done.

3. Feasibility Report
Preliminary investigation examine project feasibility, the likelihood the
system will be useful to the organization. The main objective of the feasibility
study is to test the Technical, Operational and Economical feasibility for adding
new modules and debugging old running system. All system is feasible if they
are unlimited resources and infinite time. There are aspects in the feasibility
study portion of the preliminary investigation:
Technical Feasibility
Operation Feasibility
Economic Feasibility
The technical issue usually raised during the feasibility stage of the
investigation includes the following:
Does the necessary technology exist to do what is suggested?
Does the proposed equipment have the technical capacity to hold the data
required to use the new system?
Will the proposed system provide adequate response to inquiries, regardless
of the number or location of users?
Can the system be upgraded if developed?
15
VJ COURIER SERVICE'S
Proposed projects are beneficial only if they can be turned out into
information system. That will meet the organization’s operating requirements.
Operational feasibility aspects of the project are to be taken as an important part
of the project implementation. Some of the important issues raised are to test the
operational feasibility of a project includes the following: -
Is there sufficient support for the management from the users?
Will the system be used and work properly if it is being developed and
implemented?
Will there be any resistance from the user that will undermine the possible
application benefits?
16
VJ COURIER SERVICE'S
A system can be developed technically and that will be used if installed must
still be a good investment for the organization. In the economic feasibility, the
development cost in creating the system is evaluated against the ultimate benefit
derived from the new systems. Financial benefits must equal or exceed the
costs.
The system is economically feasible. It does not require any addition
hardware or software. Since the interface for this system is developed using the
existing resources and technologies. There is nominal expenditure and
economic feasibility for certain.

OUTPUT DESIGN
OUTPUT DEFINITION
For Example
19
VJ COURIER SERVICE'S
Output Media:
The outputs were needed to be generated as a hot copy and as well as queries to
be viewed on the screen. Keeping in view these outputs, the format for the
output is taken from the outputs, which are currently being obtained after
manual processing. The standard printer is to be used as output media for hard
copies.
INPUT DESIGN
Input design is a part of overall system design. The main objective during the
input design is as given below:
INPUT STAGES:
Data recording
Data transcription
Data conversion
20
VJ COURIER SERVICE'S
Data verification
Data control
Data transmission
Data validation
Data correction
INPUT TYPES:
INPUT MEDIA:
At this stage choice has to be made about the input media. To conclude
about the input media consideration has to be given to;
Type of input
Flexibility of format
Speed
Accuracy
Verification methods
Rejection rates
Ease of correction
Storage and handling requirements
Security
Easy to use
Portability
Keeping in view the above description of the input types and input media,
it can be said that most of the inputs are of the form of internal and interactive.
21
VJ COURIER SERVICE'S
As Input data is to be the directly keyed in by the user, the keyboard can be
considered to be the most suitable input device.
ERROR AVOIDANCE
At this stage care is to be taken to ensure that input data remains accurate
form the stage at which it is recorded up to the stage in which the data is
accepted by the system. This can be achieved only by means of careful control
each time the data is handled.
ERROR DETECTION
Even though every effort is make to avoid the occurrence of errors, still a
small proportion of errors is always likely to occur, these types of errors can be
discovered by using validations to check the input data.
DATA VALIDATION
It is essential to consult the system users and discuss their needs while
designing the user interface:
22
VJ COURIER SERVICE'S
1. User initiated interface the user is in charge, controlling the progress of the
user/computer dialogue. In the computer-initiated interface, the computer
selects the next stage in the interaction.
2. Computer initiated interfaces
USER-INITIATED INTERGFACES
COMPUTER-INITIATED INTERFACES
1. The menu system for the user is presented with a list of alternatives and the
user chooses one; of alternatives.
2. Questions – answer type dialog system where the computer asks question
and takes action based on the basis of the users reply.
Right from the start the system is going to be menu driven, the opening
menu displays the available options. Choosing one option gives another popup
menu with more options. In this way every option leads the users to data entry
form where the user can key in the data.
23
VJ COURIER SERVICE'S
system the system should be designed to be helpful by providing the user with
information regarding the error he/she has committed.
24

5. SELECTED SOFTWARE
25
VJ COURIER SERVICE'S
The .NET Framework can be hosted by unmanaged components that load the
common language runtime into their processes and initiate the execution of
managed code, thereby creating a software environment that can exploit both
managed and unmanaged features. The .NET Framework not only provides
several runtime hosts, but also supports the development of third-party runtime
hosts.
26
VJ COURIER SERVICE'S
The runtime enforces code access security. For example, users can trust
that an executable embedded in a Web page can play an animation on screen or
sing a song, but cannot access their personal data, file system, or network. The
security features of the runtime thus enable legitimate Internet-deployed
software to be exceptionally featuring rich.
The runtime also enforces code robustness by implementing a strict type-
and code-verification infrastructure called the common type system (CTS). The
CTS ensures that all managed code is self-describing. The various Microsoft
and third-party language compilers
Generate managed code that conforms to the CTS. This means that
managed code can consume other managed types and instances, while strictly
enforcing type fidelity and type safety.
In addition, the managed environment of the runtime eliminates many
common software issues. For example, the runtime automatically handles object
layout and manages references to objects, releasing them when they are no
longer being used. This automatic memory management resolves the two most
common application errors, memory leaks and invalid memory references.
The runtime also accelerates developer productivity. For example,
programmers can write applications in their development language of choice,
yet take full advantage of the runtime, the class library, and components written
in other languages by other developers. Any compiler vendor who chooses to
target the runtime can do so. Language compilers that target the .NET
Framework make the features of the .NET Framework available to existing code
written in that language, greatly easing the migration process for existing
applications.
While the runtime is designed for the software of the future, it also
supports software of today and yesterday. Interoperability between managed
and unmanaged code enables developers to continue to use necessary COM
components and DLLs.
The runtime is designed to enhance performance. Although the common
language runtime provides many standard runtime services, managed code is
never interpreted. A feature called just-in-time (JIT) compiling enables all
managed code to run in the native machine language of the system on which it
is executing. Meanwhile, the memory manager removes the possibilities of
fragmented memory and increases memory locality-of-reference to further
increase performance.

LANGUAGE SUPPORT
The Microsoft .NET Platform currently offers built-in support for three
languages: C#, Visual Basic, and JScript.
33
VJ COURIER SERVICE'S
In addition to (or instead of) using <% %> code blocks to program
dynamic content, ASP.NET page developers can use ASP.NET server controls
to program Web pages. Server controls are declared within an .aspx file using
custom tags or intrinsic HTML tags that contain a runat="server" attributes
value. Intrinsic HTML tags are handled by one of the controls in the
System.Web.UI.HtmlControls namespace. Any tag that doesn't explicitly map
to one of the controls is assigned the type of
System.Web.UI.HtmlControls.HtmlGenericControl.

DataSets
The DataSet object is similar to the ADO Recordset object, but more powerful,
and with one other important distinction: the DataSet is always disconnected.
The DataSet object represents a cache of data, with database-like structures
such as tables, columns, relationships, and constraints. However, though a
DataSet can and does behave much like a database, it is important to remember
that DataSet objects do not interact directly with databases, or other source
data. This allows the developer to work with a programming model that is
always consistent, regardless of where the source data resides. Data coming
from a database, an XML file, from code, or user input can all be placed into
DataSet objects. Then, as changes are made to the DataSet they can be tracked
and verified before updating the source data. The GetChanges method of the
DataSet object actually creates a second DatSet that contains only the changes
to the data. This DataSet is then used by a DataAdapter (or other objects) to
update the original data source.
The DataSet has many XML characteristics, including the ability to produce
and consume XML data and XML schemas. XML schemas can be used to
describe schemas interchanged via WebServices. In fact, a DataSet with a
schema can actually be compiled for type safety and statement completion.
DATAADAPTERS (OLEDB/SQL)
The DataAdapter object works as a bridge between the DataSet and the
source data. Using the provider-specific SqlDataAdapter (along with its
associated SqlCommand and SqlConnection) can increase overall
performance when working with a Microsoft SQL Server databases. For other
OLE DB-supported databases, you would use the OleDbDataAdapter object
and its associated OleDbCommand and OleDbConnection objects.
The DataAdapter object uses commands to update the data source after
changes have been made to the DataSet. Using the Fill method of the
DataAdapter calls the SELECT command; using the Update method calls the
INSERT, UPDATE or DELETES command for each changed row. You can
explicitly set these commands in order to control the statements used at runtime
to resolve changes, including the use of stored procedures. For ad-hoc scenarios,
a CommandBuilder object can generate these at run-time based upon a select
statement. However, this run-time generation requires an extra round-trip to the

RELATIONAL DATABASE
FOREIGN KEY
When a field is one table matches the primary key of another field is
referred to as a foreign key. A foreign key is a field or a group of fields in one
table whose values match those of the primary key of another table.
REFERENTIAL INTEGRITY
Not only does SQL Server allow you to link multiple tables, it also
maintains consistency between them. Ensuring that the data among related
tables is correctly matched is referred to as maintaining referential integrity.

DATA ABSTRACTION
Physical level: This is the lowest level of abstraction at which one describes
how the data are actually stored.
Conceptual Level: At this level of database abstraction all the attributed and
what data are actually stored is described and entries and relationship among
them.
View level: This is the highest level of abstraction at which one describes only
part of the database.

UNMATCHED PERFORMANCE
The most advanced architecture in the industry allows the SQL SERVER
DBMS to deliver unmatched performance.
NO I/O BOTTLENECKS
SQL Server’s fast commit groups commit and deferred write technologies
dramatically reduce disk I/O bottlenecks. While some database write whole data
block to disk at commit time, SQL Server commits transactions with at most
sequential log file on disk at commit time, On high throughput systems, one
sequential writes typically group commit multiple transactions. Data read by
43
VJ COURIER SERVICE'S
the transaction remains as shared memory so that other transactions may access
that data without reading it again from disk. Since fast commits write all data
necessary to the recovery to the log file, modified blocks are written back to the
database independently of the transaction commit, when written from memory
to disk.

6.1. INTRODUCTION
44
VJ COURIER SERVICE'S
of an entity that will later be built. Beginning, once system requirement have
been specified and analyzed, system design is the first of the three technical
activities -design, code and test that is required to build and verify software.
The importance can be stated with a single word “Quality”. Design is the
place where quality is fostered in software development. Design provides us
with representations of software that can assess for quality. Design is the only
way that we can accurately translate a customer’s view into a finished software
product or system. Software design serves as a foundation for all the software
engineering steps that follow. Without a strong design we risk building an
unstable system – one that will be difficult to test, one whose quality cannot be
assessed until the last stage.
45
VJ COURIER SERVICE'S
6.3. NORMALIZATION
It is a process of converting a relation to a standard form. The process is
used to handle the problems that can arise due to data redundancy i.e. repetition
of data in the database, maintain data integrity as well as handling problems that
can arise due to insertion, updation, deletion anomalies.
Decomposing is the process of splitting relations into multiple relations to
eliminate anomalies and maintain anomalies and maintain data integrity. To do
this we use normal forms or rules for structuring relation.
46
VJ COURIER SERVICE'S
Normal Forms: These are the rules for structuring relations that eliminate
anomalies.
A relation is said to be in first normal form if the values in the relation are
atomic for every attribute in the relation. By this we mean simply that no
attribute value can be a set of values or, as it is sometimes expressed, a
repeating group.
47
VJ COURIER SERVICE'S
6.4. E – R DIAGRAMS
The relation upon the system is structure through a conceptual ER-Diagram, which
not only specifics the existential entities but also the standard relations through
which the system exists and the cardinalities that are necessary for the system state
to continue.
The entity Relationship Diagram (ERD) depicts the relationship between the data
objects. The ERD is the notation that is used to conduct the date modeling activity
the attributes of each data object noted is the ERD can be described resign a data
object descriptions.
The set of primary components that are identified by the ERD are
Data object Relationships
Attributes Various types of indicators.
The primary purpose of the ERD is to represent data objects and their relationships.

The idea behind the explosion of a process into more process is that
understanding at one level of detail is exploded into greater detail at the next
level. This is done until further explosion is necessary and an adequate amount
of detail is described for analyst to understand the process.
DFD SYMBOLS:
Data flow
50
VJ COURIER SERVICE'S
Data Store
CONSTRUCTING A DFD:
1. Process should be named and numbered for an easy reference. Each name
should be representative of the process.
2. The direction of flow is from top to bottom and from left to right. Data
traditionally flow from source to the destination although they may flow
back to the source. One way to indicate this is to draw long flow line back to
a source. An alternative way is to repeat the source symbol as a destination.
Since it is used more than once in the DFD it is marked with a short
diagonal.
3. When a process is exploded into lower level details, they are numbered.
4. The names of data stores and destinations are written in capital letters.
Process and dataflow names have the first letter of each work capitalized
A DFD typically shows the minimum contents of data store. Each data
store should contain all the data elements that flow in and out.
Questionnaires should contain all the data elements that flow in and out.
Missing interfaces redundancies and like is then accounted for often through
interviews.
1. The DFD shows flow of data, not of control loops and decision are
controlled considerations do not appear on a DFD.
2. The DFD does not indicate the time factor involved in any process whether
the dataflow take place daily, weekly, monthly or yearly.
3. The sequence of events is not brought out on the DFD.
TYPES OF DATA FLOW DIAGRAMS
1. Current Physical

2. Current Logical
3. New Logical
4. New Physical
CURRENT PHYSICAL:
In Current Physical DFD process label include the name of people or
their positions or the names of computer systems that might provide some of the
overall system-processing label includes an identification of the technology
used to process the data. Similarly data flows and data stores are often labels
with the names of the actual physical media on which data are stored such as
file folders, computer files, business forms or computer tapes.
CURRENT LOGICAL:
NEW LOGICAL:
This is exactly like a current logical model if the user were completely
happy with he user were completely happy with the functionality of the current
system but had problems with how it was implemented typically through the
new logical model will differ from current logical model while having
additional functions, absolute function removal and inefficient flows
recognized.
NEW PHYSICAL:
The new physical represents only the physical implementation of the new
system.
RULES GOVERNING THE DFD’S
PROCESS
1) No process can have only outputs.
2) No process can have only inputs. If an object has only inputs than it must be
a sink.
3) A process has a verb phrase label.
52
VJ COURIER SERVICE'S
DATA STORE
1) Data cannot move directly from one data store to another data store, a
process must move data.
2) Data cannot move directly from an outside source to a data store, a process,
which receives, must move data from the source and place the data into data
store
3) A data store has a noun phrase label.
SOURCE OR SINK
1) Data cannot move direly from a source to sink it must be moved by a process
2) A source and /or sink has a noun phrase land
DATA FLOW
1) A Data Flow has only one direction of flow between symbols. It may flow
in both directions between a process and a data store to show a read before
an update. The later is usually indicated however by two separate arrows
since these happen at different type.
2) A join in DFD means that exactly the same data comes from any of two or
more different processes data store or sink to a common location.
3) A data flow cannot go directly back to the same process it leads. There must
be at least one other process that handles the data flow produce some other
data flow returns the original data into the beginning process.
4) A Data flow to a data store means update (delete or change).
5) A data Flow from a data store means retrieve or use.
A data flow has a noun phrase label more than one data flow noun phrase can
appear on a single arrow as long as all of the flows on the same arrow move
together as one package.

8.1. INTRODUCTION
Software testing is a critical element of software quality assurance and
represents the ultimate review of specification, design and coding. In fact,
testing is the one step in the software engineering process that could be viewed
as destructive rather than constructive.
A strategy for software testing integrates software test case design
methods into a well-planned series of steps that result in the successful
construction of software. Testing is the set of activities that can be planned in
advance and conducted systematically. The underlying motivation of program
testing is to affirm software quality with methods that can economically and
effectively apply to both strategic to both large and small-scale systems.

VJ COURIER SERVICE'S
develop computer software we spiral in along streamlines that decrease the level
of abstraction on each turn.
A strategy for software testing may also be viewed in the context of the
spiral. Unit testing begins at the vertex of the spiral and concentrates on each
unit of the software as implemented in source code. Testing progress by moving
outward along the spiral to integration testing, where the focus is on the design
and the construction of the software architecture. Talking another turn on
outward on the spiral we encounter validation testing where requirements
established as part of software requirements analysis are validated against the
software that has been constructed. Finally we arrive at system testing, where
the software and other system elements are tested as a whole.

V(G)=E-N+2 or
V(G)=P+1 or
V(G)=Number Of Regions
3. CONDITIONAL TESTING
In this part of the testing each of the conditions were tested to both true and
false aspects. And all the resulting paths were tested. So that each path that may
be generate on particular condition is traced to uncover any possible errors.
71
VJ COURIER SERVICE'S
This type of testing selects the path of the program according to the location of
definition and use of variables. This kind of testing was used only when some
local variable were declared. The definition-use chain method was used in this
type of testing. These were particularly useful in nested statements.
5. LOOP TESTING
In this type of testing all the loops are tested to all the limits possible. The
following exercise was adopted for all loops:
All the loops were tested at their limits, just above them and just below them.
All the loops were skipped at least once.
For nested loops test the inner most loop first and then work outwards.
For concatenated loops the values of dependent loops were set with the help
of connected loop.
Unstructured loops were resolved into nested loops or concatenated loops
and tested as above.
Each unit has been separately tested by the development team itself and all the
input have been validated.

Various client side validations are used to ensure on the client side that only
valid data is entered. Client side validation saves server time and load to handle
invalid data. Some checks imposed are:

JavaScript in used to ensure those required fields are filled with suitable data
only. Maximum lengths of the fields of the forms are appropriately defined.
Forms cannot be submitted without filling up the mandatory data so that
manual mistakes of submitting empty fields that are mandatory can be sorted
out at the client side to save the server time and load.
Tab-indexes are set according to the need and taking into account the ease of
user while working with the system.
Some checks cannot be applied at client side. Server side checks are necessary
to save the system from failing and intimating the user that some invalid
operation has been performed or the performed operation is restricted. Some of
the server side checks imposed is:
Server side constraint has been imposed to check for the validity of primary
key and foreign key. A primary key value cannot be duplicated. Any attempt
to duplicate the primary value results into a message intimating the user
about those values through the forms using foreign key can be updated only
of the existing foreign key values.
User is intimating through appropriate messages about the successful
operations or exceptions occurring at server side.
Various Access Control Mechanisms have been built so that one user may
not agitate upon another. Access permissions to various types of users are
controlled according to the organizational structure. Only permitted users
can log on to the system and can have access according to their category.
User- name, passwords and permissions are controlled o the server side.
Using server side validation, constraints on several restricted operations are
imposed.

10.CONCLUSION
The project is identified by the merits of the system offered to the user. The
merits of this project are as follows: -
It’s a web-enabled project.
This project offers user to enter the data through simple and interactive
forms. This is very helpful for the client to enter the desired information
through so much simplicity.
The user is mainly more concerned about the validity of the data, whatever
he is entering. There are checks on every stages of any new creation, data
entry or updating so that the user cannot enter the invalid data, which can
create problems at later date.
Sometimes the user finds in the later stages of using project that he needs to
update some of the information that he entered earlier. There are options for
him by which he can update the records. Moreover there is restriction for his
that he cannot change the primary data field. This keeps the validity of the
data to longer extent.
User is provided the option of monitoring the records he entered earlier. He
can see the desired records with the variety of options provided by him.
From every part of the project the user is provided with the links through
framing so that he can go from one option of the project to other as per the
requirement. This is bound to be simple and very friendly as per the user is
75

concerned. That is, we can say that the project is user friendly which is one
of the primary concerns of any good project.
Data storage and retrieval will become faster and easier to maintain because
data is stored in a systematic manner and in a single database.
Decision making process would be greatly enhanced because of faster
processing of information since data collection from information available
on computer takes much less time than manual system.
Allocating of sample results becomes much faster because at a time the user
can see the records of last years.
Easier and faster data transfer through latest technology associated with the
computer and communication.
Through these features it will increase the efficiency, accuracy and
transparency,
LIMITATIONS:
The size of the database increases day-by-day, increasing the load on the
database back up and data maintenance activity.
Training for simple computer operations is necessary for the users working
on the system.

A console for the data center may be made available to allow the
personnel to monitor on the sites which were cleared for hosting during a
particular period.
