PRELIMINARY
INVESTIGATION

INTRODUCTION
Property dealing project is a user friendly software developed in Vb.net
programming language as front end and SQL server database as back end.
This project is designed to save the data of all those persons who will hire,
lease or buy any kind of property like buildings, flats, plots etc. which will
reduce manual work and helps the dealer to save the records efficiently. This
project is aimed at developing a Property Dealer Software. It provides the
simplest, cheapest and an less time and energy consuming way of Property
Dealing.
In old days, the Property Dealer may have to keep records of the
properties manually. This method of keeping the records is quiet time
consuming and less efficient. Also there are more chances of mistakes by
keeping the records manually as human beings are habitual of doing mistakes.
So with the help of this, Property Dealing Software, the chances of mistakes
becomes very few. Also it is very efficient method of keeping the records of
properties sold as well as unsold properties. It consumes very less time as
compared to manual method.
The application is divided into three modules. The admin i.e. the
Property Dealer itself handles the whole software . He managed the database
as well as all the records.
6

Present System and Limitation
In old days, the Property Dealer may have to keep records of the
properties manually on the papers. This method of keeping the records is
quiet time consuming and less efficient. Also there are more chances of
mistakes by keeping the records manually as human beings are habitual of
doing mistakes.
There are several types of cost associated with manual records. One
type , duplication of the record, requires paper and copying supplies, as well
as the staff to create and distribute the copies. Staff hired to assemble, file,
retrieve, or distribute the hard copy chart is a costly expenses. Storage of the
paper record necessitates the use of valuable space that could be better
utilized. The records also need to be protected from water, fire, or
mishandling of the paper to preserve their physical integrity. Staff members
time required to deliver paper records to a specific location. If the paper
record is not readily available, clerical staff responsible for filling
documentation may need to make several attempts before the task is
completed. There is no ability to sort data fields in a paper record. Staff
responsible for reporting mandated data elements to the appropriate
organizations must perform a manual review. There is limitation to the
physical quality of the paper record. Paper is fragile and does not last
permanently. Normal use of the record may result in torn or stained
documents also over the years, ink used to complete documentation can fade.
Actual damage resulting from water or fire is another threat to the physical
integrity of the paper records.
Major Disadvantage:
• Cost of manual records
• Lost productivity from manual records
• Accessibility of records
• Quality of manual records
7

• Fragmentation caused by manual records
PROPOSED SYSTEM
Features:
 All the records and data have been computerized and are now
persistent.
 Manual calculations have been automated.
 Access to all types of records made easy.
 The proposed system is a computerized system.
 The customer has to just give his details like contact number, address,
Number of person accommodating with him and also the mode of
payment along with his details.
 It also maintain record of all people who have visited their hotel, has a
stay before through a database.
 Paper work is avoid.
Advantages of Proposed System:
 This system is User-friendly, interactive and easy to use.
 Save excess paper work.
 Time saving.
 No complexities.
 Data security and backup facility.
8

 The system simplifies the work of searching and adding the details of
customer.
 Formatted data.
 Records/ information’s are easily approachable.
 The calculation can be done automatically.
FEASIBILITY STUDY
 Preliminary Investigation is the first phase in any system developing
life cycle. The Feasibility Study is a major part of this phase.
 Feasibility Study means selecting the best system that meet the
performance requirement.
 It is the measure of how beneficial or practical the development of an
Information System would be to the organization.
 Our study of the feasible development of the software is going to be in
terms of the following aspects:
Operational Feasibility:
Proposed system is beneficial only if it can be turned into management
system that will meet the need of the client’s operating requirements.
Kalidasa Library’s work is increasing day by day.
The proposed system is operationally feasible due to the following reasons:
• The system is easy to use and is very simple.
• The proposed system will cost no harm to the company; instead it
will enhance the result in a better respect.
• The new system will avoid confusion and resistance by catching the
user’s attention, as it is presentable.
9

Economical Feasibility:
1. Development Cost
• Equipments required for developing the software are easily available.
• Equipment maintenance is also minimum.
• Saving of paper work and manpower reduced.
• Once the required hardware and software requirements get fulfilled
there is no need for the user of our system to spend for any additional
overhead.
• Training cost is reduced.
2. Benefits which cannot be measured:
• Increased customer Loyalty
• Increased customer satisfaction
Technical Feasibility:
At first it is necessary to check that the proposed system is technically
feasible or not and to determine the technology and skill necessary to carry
out the project. If they are not available then find out the solution to obtain
them. Hardware is already available in the college.
Social feasibility:.
Although generally there is always resistance, initially to any change in
the system is aimed at relieving the workload of the users to extent the system
is going to facilitate user to perform operations like calculating salary
amounts and deductions, generating the reports using data reports with less
possible errors. Thus there is no reason to make system socially unfeasible

METHODOLOGY ADOPTED
Incremental Model (IM):-
This model derives its name from the way in which the software is
built. More specifically, the model is designed, implemented and tested as a
series of incremental builds until the product is finished. A build consists of
pieces of code from various modules that interact together to provide a
specific function.
At each stage of IM, a new build is coded and then integrated into the
structure which is tested as a whole. Note that the product is defined as
finished only when it satisfies all of its requirements.
This model combines the elements of Waterfall model with the iterative
philosophy of prototyping. However, unlike prototyping the IM focuses on
the delivery of an operational product at the end of each increment.
14

The first increment is usually the core product which addresses the
basic requirements of the system. This may be either be used by the client or
subjected to detailed review to develop plan for the next increment.
Essentially the build with the highest value-to-cost ratio is the one that
provides the client with the most functionality (value) for the least cost. Using
this method, the client has a usable product at all of the development stages.
15

SYSTEM ANALYSIS
16

EVENTS
An event occurs at a specific time & place, that can be described & is worth
remembered by the system. Events drive or trigger all processing that a
system does, so listing them & then analyzing them make sense when you
need to define system requirements.
EXTERNAL EVENT:
An event that occurs outside the system usually initiated by an external
agent or actor.
TEMPORAL EVENT:
An event that occurs as a result of reaching a point in time.
EVENT TABLE
A table that lists events in rows & key pieces of information about
each event in columns.
TRIGGER:
An occurrence that tells the system that an event has occurred, either
the arrival of data needing processing or of point in time.
SOURCE:
An external agent or actor that supplies data to the system.
ACTIVITY:
Behavior that the system performs when an event occurs.
RESPONSE:
An output, produce by the system that goes to the system.
DESTINATION:
An external agent or actor that receives data from the system.

USE CASE DIAGRAM
Use Case Diagram is used to identify the “uses” or use cases of
the new system-- in other words, to identify how the system will be used
.The Use Case Diagram is essentially an extension of the Event Table.
USE CASE:
It describes an activity the system carries out in response to an
event.
ACTOR:
In UML, the person involved is called an Actor. An Actor is always
outside of the Automation Boundary of the system.
CONNECTING LINE:
The arrow is used to show which Actors participate in which Use
cases.
19

USE CASE DIAGRAM NOTATIONS:
DESCRIPTION:
The Object Oriented approach uses the term use case to describe
an activity the system carries out in response to an event. One can think
of a use case as a case or situation where the system is used for some
purpose .A use case diagram is a convenient way to document the
functions that the system must support. Sometimes a single,

comprehensive diagram is used to describe the entire system. At other
times, a set of smaller use case diagrams make up the use case model.

The entity – relationship (ER) data model allows us to describe the
data involved in a real world enterprise in terms of object and their
relationships and is widely used to develop an initial database design.
The ER model is important primarily for its role in database design. It
provides useful concepts that allow us to move from an informal description
of what users want from their database to a more detailed and precise
description that can be implemented in a DBMS. The ER model is used in a
phase called “Conceptual Database Design”. It should be noted that many
variations of ER diagrams are in use and no widely accepted standards
prevail.
ER modeling is something regarded as a complete approach to design a
logical database schema. This is incorrect because the ER diagram is just an
approximate description of data, constructed through a very subjective
evaluation of the information collected during requirements analysis.
Entity:
An entity is an object in the real world that is distinguishable from
other objects. Examples include the following: The C++ language, the address
of the manager of the institution. It is often useful to identify a collection of
similar entities. Such a collection is called as “Entity set”. Note that entity set
need not be disjoint.
Attributes:
An entity is described using a set of attributes. All entities in a given
entity set have the same attributes; this essentially what we mean by similar.
Our choice of attributed reflects the level of detail at which we wish to
represent information in crisis.
Domain:
For each attribute associated with an entity set, we must identify a
domain of possible values. For e.g. the domain associated with the attribute
name of the student might be of the set of 20-character string. Another
example would be the ranking of the students in the institute would be on the
scale of 1-6, the associated domain consists of integers 1 through 6.
Key:
22

Further, for each entity set we choose a key. A key is a minimal set of
attributed whose values uniquely identify an entity in the set. There could be
more than one candidate; if so we designate one of them as primary key. For
now we will assume that each entity set contains at least one set of attributes
that uniquely identify an entity in the entity set; that is the set of attributes
contains a key.

Activity diagrams are graphical representations of workflows of
stepwise activities and actions with support for choice, iteration and
concurrency. In the Unified Modeling Language, activity diagrams can be
used to describe the business and operational step-by-step workflows of
components in a system. An activity diagram shows the overall flow of
control.
The most important shape types:
• Rounded rectangles represent activities;
• Diamonds represent decisions;
• Bars represent the start (split) or end (join) of concurrent activities;
• A black circle represents the start (initial state) of the workflow;
• An encircled black circle represents the end (final state).
• Arrows run from the start towards the end and represent the
orderwhich activities happen.

CLASS DIAGRAM
CLASS DIAGRAM:
The Class diagrams are used to identify and classify the
objects which constitute a system. It also includes the important
attributes of the objects which must be captured.
CLASS:
It is a collection of objects of same type.
RELATIONSHIP:
A naturally occurring association among specific things.
CLASS DIAGRAM NOTATIONS:
In Class diagram, rectangles represent Class and the lines
connecting the rectangle show the relationships among Classes.
DESCRIPTION:
It is a model which is used to show the classes constituting a
system and their interrelationships .It is based on UML (Unified
Modeling Language). Only the important attributes and methods are
shown in Class Diagrams. In the initial period of analysis, the important
attributes of the classes, which must be captured and the functionalities
provided by the class may not be very clear . As the analysis progresses,
the attributes and methods may be added.

OBJECT DIAGRAM
Object diagrams are derived from class diagrams so object diagrams are
dependent upon class diagrams.
Object diagrams represent an instance of a class diagram. The basic concepts
are similar for class diagrams and object diagrams. Object diagrams also

represent the static view of a system but this static view is a snapshot of the
system at a particular moment.
So the purpose of the object diagram can be summarized as:
• Forward and reverse engineering.
• Object relationships of a system
• Static view of an interaction.
• Understand object behavior and their relationship from practical
perspective.

SEQUENCE DIAGRAM
A Sequence Diagram has the following features:
 A Sequence diagram describes interactions among classes in terms of
an “exchange of messages over time”.
Some of the facts related to Sequence Diagrams are:
 Sequence Diagrams are used to depict the time sequence of messages
exchanged between objects.
 Messages can correspond to operation on class or a event trigger.
Notations of a Sequence diagram include:
 Lifeline: It is a vertical dashed line that represents the “lifetime” of an
Object.
 Arrows: They indicate flow of messages between objects.
 Activation: It is a thin rectangle showing period of time, during which
an object is performing an action.

STATE CHART DIAGRAM
A State Chart Diagram describes the dynamic behavior of a system in
response to external stimuli.
A State Chart Diagram helps:
 To model dynamic behavior of objects based on states.
 To model reactive objects, whose states are triggered by specific
events.
 To describe passive objects, which go through several distinct phases
during
their life time.
Parts of a State are:
 Name: Unique name identifying the state
 Sub-states: Set of “disjoint sub-states” or “concurrent sub-states”.
 State – Sub-state relationship: Useful to understand the modeling of
complex
behaviors.
 Entry action: An action that happens as a result of transition into a
state
 Exit action: An action that has to happen immediately before a state
change.
 Internal activity: Activities that occur within an object while it is in a
particular
state.

CONVERTING ERD TO TABLE
An ERD is a pictorial representation of the interaction that can be captured by
database.
Converting ERD to table helps:
 It allows database professionals to describe an overall design concisely
get accurately.
 It can be easily transformed into the relational schema.
Parts are:
 Entity Sets.
 Relationship Sets.
We will convert each entity set to table, which involves deciding the tables.

COMPONENT DIAGRAM
Component Diagrams describe the organization of components, including
source code, run-time (binary) code, and executables.
Component Diagrams:
 Give the physical view of the system in terms of implementation
aspect. This is important for reusability and performance purpose.
 Constitute the Components, their interfaces and realizations, and
dependencies between Components
Component Diagrams are used:
 To depict organizations and dependencies among Component type.
 To show allocation of “classes” and “objects” to Components (also
referred to as modules) in the physical design of the system.
 To indicate the “physical layering” and “partitioning” of the system
Architecture

A Component typically encompasses:
 Structure and behavior of a “collaboration of classes” from the system
design.
 Interfaces that describe a group of operations implemented by
Components
39

 Realization which is the relationship between an “interface” and the
“class” that
provides the interface’s services

PACKAGE DIAGRAM
A package diagram in the Unified Modeling Language depicts the
dependencies between the packages that make up a model.
In addition to the standard UML Dependency relationship, there are
two special types of dependencies defined between packages:
package import
package merge
A package import is "a relationship between an importing namespace
and a package, indicating that the importing namespace adds the names of the
members of the package to its own namespace." [1] By default, an unlabeled
dependency between two packages is interpreted as a package import
relationship.
A package merge is "a directed relationship between two packages, that
indicates that the contents of the two packages are to be combined. It is very
similar to Generalization in the sense that the source element conceptually
adds the characteristics of the target element to its own characteristics
resulting in an element that combines the characteristics of both"[2]
Package diagrams can use packages containing use cases to illustrate
the functionality of a software system.
Package diagrams can use packages that represent the different layers
of a software system to illustrate the layered architecture of a software
system. The dependencies between these packages can be adorned with labels
stereotypes to indicate the communication mechanism between the layers.

DEPLOYMENT DIAGRAM
A deployment diagram in the Unified Modeling Language models the
physical deployment of artifacts on nodes.[1] To describe a web site, for
example, a deployment diagram would show what hardware components
("nodes") exist (e.g., a web server, an application server, and a database
server), what software components ("artifacts") run on each node (e.g., web
application, database), and how the different pieces are connected (e.g. JDBC,
REST, RMI).
The nodes appear as boxes, and the artifacts allocated to each node
appear as rectangles within the boxes. Nodes may have sub nodes, which
appear as nested boxes. A single node in a deployment diagram may
conceptually represent multiple physical nodes, such as a cluster of database
servers.

Technology Used
Overview of the .NET Framework
The .NET Framework is a new computing platform that simplifies application
development in the highly distributed environment of the Internet.
The .NET Framework is designed to fulfill the following objectives:
• To provide a consistent object-oriented programming environment
whether object code is stored and executed locally, executed locally but
Internet-distributed, or executed remotely.
• To provide a code-execution environment that minimizes software
deployment and versioning conflicts.
• To provide a code-execution environment that guarantees safe execution
of code, including code created by an unknown or semi-trusted third
party.
• To provide a code-execution environment that eliminates the performance
problems of scripted or interpreted environments.
• To make the developer experience consistent across widely varying types
of applications, such as Windows-based applications and Web-based
applications.
• To build all communication on industry standards to ensure that code
based on the .NET Framework can integrate with any other code.
46

Front End:- Vb.Net
Visual Basic .NET (VB.NET) is an object-oriented computer programming
language implemented on the .NET Framework. Although it is an evolution
of classic Visual Basic language, it is not backwards-compatible with VB10,
and any code written in the old version does not compile under VB.NET.
Like all other .NET languages, VB.NET has complete support for object-
oriented concepts. Everything in VB.NET is an object, including all of the
primitive types (Short, Integer, Long, String, Boolean, etc.) and user-defined
types, events, and even assemblies. All objects inherits from the base class
Object.
VB.NET is implemented by Microsoft's .NET framework. Therefore, it has
full access to all the libraries in the .Net Framework. It's also possible to run
VB.NET programs on Mono, the open-source alternative to .NET, not only
under Windows, but even Linux or Mac OSX.
The following reasons make VB.Net a widely used professional language:
• Modern, general purpose.
• Object oriented.
• Component oriented.
• Easy to learn.
• Structured language.
47

• It produces efficient programs.
• It can be compiled on a variety of computer platforms.
• Part of .Net Framework.
 Common Language Run Time(CLR)
CLR is an application virtual machine that provides important services such
as security, memory management, and exception handling. Programs written
for the .NET Framework execute in a software environment which is known
as CLR. The application that run under the CLR are called managed code.
CLR is the foundation of the .NET Framework. You can think of the runtime
as an agent that manages code at execution time, providing core services such
as memory management, thread management, and remoting, while also
enforcing strict type safety and other forms of code accuracy that ensure
security and robustness. In fact, the concept of code management is a
fundamental principle of the runtime. Code that targets the runtime is known
as managed code, while code that does not target the runtime is known as
unmanaged code. The class library, the other main component of the .NET
Framework, is a comprehensive, object-oriented collection of reusable types
that you can use to develop applications ranging from traditional command-
line or graphical user interface (GUI) applications to applications based on
the latest innovations provided by ASP.NET, such as Web Forms and XML
Web services.
Common Language Specification (CLS):
To fully interact with other objects regardless of the language they were
implemented in, objects must expose to callers only those features that are
common to all the languages they must interoperate with. For this reason, the
Common Language Specification (CLS), which is a set of basic language
features needed by many applications, has been defined.

Microsoft SQL Server is a relational database management system developed by Microsoft.
As a database, it is a software product whose primary function is to store and retrieve data as
requested by other software applications, be it those on the same computer or those running
on another computer across a network (including the Internet). SQL Server 2010 was
released in 2010. It included native support for managing XML data, in addition to relational
data. Common Language Runtime (CLR) integration was introduced with this version,
enabling one to write SQL code as Managed Code by the CLR. SQL Server 2010 has also
been enhanced with new indexing algorithms, syntax and better error recovery systems.
CLR was introduced with SQL Server 2005 to let it integrate with the .NET Framework.

TESTING
Testing Objectives
 Testing is a process of executing a program with the intent of finding
an error or debug.
 A good test case is one that has a high probability of finding yet not
discovered errors.
Unit Testing
Unit testing using white-box-testing to test each smallest unit or
component of the module like Interface, Local Data Structure, Boundary
Conditions, Independent and Error Handling Paths using appropriate test
cases.
Integration Testing
105

Integration Testing using Top-Down Integration to test data
and its value before and after flowing from one to another module
during and after integration of module.
Code Testing
The code testing examines the logic of the program. To
follow this testing we have developed test cases that result in
every instruction in the module; every path is specific
combination of conditions that is handled by the program
Validation Testing
Validation testing to validate system functionalities, that they
are traceable to customer requirements.
System Testing
System testing to test efficiency with all minimum hardware
and software requirements of system after installation
106

Future Scope
In future, a system may be developed which can be used online by the users
who want to sale or purchase properties. In such a system the users may deal
directly with each other, they do not need a property dealer as an
intermediate. Also they are not supposed to go to the property dealer for their
deals; they can directly use the software online. Moreover the users do not
need to pay extra amounts as in case of a property dealer who helped in the
deals, whatever amount the seller needs, is paid by the purchaser. This saves
money as well as time too. So, in future a lot of manipulations can be done
keeping in view the requirements of the users.
1. If the system works as an online system, it becomes more efficient as
compared to the one which is used offline only by a property dealer.
2. Such a system saves time as well as money of the users too.
107

3. There is no need of a property dealer as an intermediate between the seller
and purchaser.
4. The seller and purchaser can contact directly to each other.
5. Enhance its features and increasing the number of services provided.
6. Implementing higher level of security.
Conclusion
The development of the proposed system is done keeping in view the
problems of agent i.e. property dealer in the official dealings of properties.
Typically a dealer buys the property from one party and sells to another. Thus
the dealer’s profit is the difference between the price he pays to one party and
the price he receives from another party for the same property. In short, the
dealers have a particular commission in it. Also there are Real estate agents
who undertake a diversity of activities related to the selling and leasing of
residential and commercial property. Many agents specialize in areas of
practice such as residential sales, residential property management,
commercial and industrial leasing and sales, representing buyers, rural sales
and more. For this we have to pay them with heavy amounts.
108

With the use of this software, the property dealer does not need to store the
records of dealings into registers or papers. So, it becomes easier for him to
keep the records for future references. Also it becomes much easier to keep a
record of properties which are being sold or which are not sold yet. Thus this
system saves time and is easier to use. Moreover, it is efficient software for
property dealers.
