1. PROBLEM STUDY
1.1 INTRODUCTION
If your company is more than 10 years old, its structure is probably wrong in many
ways. Customers know it, employees know it, and investors know it. Multiple key processes,
and the organizational and financial models that support them, were likely architected for
yesterday’s world of widgets and are floundering in today’s onslaught of digits. The year
2012 is a very important one in corporate IT, as the social, mobile, analytics and cloud
technologies that have so dominated the consumer experience for the past several years
entered the enterprise world in a meaningful way, laying the foundation for a new master
corporate IT architecture. Key to understanding this transition — and knowing what to do
about it — is in viewing SMAC technologies as a “stack,” as an integrated architecture.
Imagine your smartphone without its apps, disconnected from the Web, the cloud and your
personal networks. On its own, it would be a very expensive pocket watch. Remaining part of
the document explores the various facets related to SMAC stack implementation in a real
estate application.
1.2 OBJECTIVE
To design an optimized search filtering algorithm and software that will provide best
deals to the user who is need of any sort of real estate (whether it be plots, flats, etc.) by
spying onto his search activity, social activities (Facebook posts, Twitter posts etc.) and his
mobile search activities. The project aims to target the business clients who want to sell good
deals to their customers by identifying the prospective ones. This identification will be done
by our analytic algorithm which will ultimately gather information from all the arenas
whether it be Facebook, twitter, normal search etc. compile it and at the end filter so as to
bring out the optimized results.

1.3 PROBLEMS IN EXISTING SYSTEM
In the contemporary world people like to get their needs served at the repose of their
comfort. All the companies strive for maximum customer satisfaction and have a motto to
provide best options to their respective customers effortlessly. Absence of such a medium
that fulfills the customer’s requirement and is equally lucrative for the companies is where
our project comes into play. We provide a general user with deals of his interest without him
actually rigorously searching for the same by keeping a track of his digital activities and
forwarding such information to our client so that he can fulfil the general user’s requirements.
When we first studied salesforce and PropertyBase, we realised that India Lacks far behind in
this aspect. We just have websites like magicBricks and 99acres which serve the property
needs of people but that too upto a limited extent. There was no concept of listings and offers
and analytics which are applied in India so that we get an optimised result. In USA, a term
called MLS Listing is very popular. This concept isn’t used in India, hence apart from MLS
listing we tried to incorporate all the essential features of PropertyBase into our Indian model.
2. FEASIBILITY STUDY
The aim of a feasibility study is to see whether it is possible to develop a system at a
reasonable cost. At the end of the feasibility study a decision is taken whether to proceed or
not. A feasibility study contains the general requirements of the proposed system. System
feasibility is merely of three kind’s economical, technical and behavioural feasibility.
2.1 ECONOMICAL
It could also be referred to as cost/benefit analysis. It is used for evaluating the effectiveness
of a system. In economic analysis the procedure is to determine the benefits and savings that
are expected from a system and compare them with costs. This software is designed with the
aim of expanding the buyer-seller relations without actually getting them to involve much of
the task, hence providing lucrative benefits to buyer as well as equally benefitting the user, by
exploring his requirements and providing the best-ones in terms of cost for his benefit.

___________________________________________________________________________
3 | P a g e
2.2 TECHNICAL
It is the study of configuration of the system. It considers the technical requirements of the
project. We have used Eclipse IDE as the developer tool and advanced java components to
develop the project. For storage of data that is back hand we have used My SQL. MySQL
editor used is SQLYog enterprise. The website designing toolkit Dreamweaver and CSS style
sheets are used. For use case and UML diagrams Rational Software Architect
2.3 BEHAVIORAL
It is dependent on human resources surfing the internet by any means and henceforth
providing an opportunity to explore their needs and also predict their future requirements on
the basis of their present ones. This application will provide ground to extract all such data.
This application will save time and provide the business client’s their pool of probable
customers at any moment of time. It is secure, time saving and easy hence allowing buyer-
seller to grow in terms of business opportunities and relations.

4. SYSTEM ANALYSIS
Requirements analysis in systems engineering and software engineering,
encompasses those tasks that go into determining the needs or conditions to meet for a new or
altered product, taking account of the possibly conflicting requirements of the
various stakeholders, analyzing, documenting, validating and managing software or system
requirements.
4.1 INFORMATION GATHERING
Analyzing a similar SMAC based real estate application-property base and a case
study of net-flex helped us to get the understanding of real time implementation of a similar
model, and developing a similar real estate model for real estate industry was the basic
objective. Absence of such a model in a growing economy was the basic need that was
identified. In order to better understand the customer searching tactics some real estate web-
sites operating in our country were also studied. With emerging power of a growing country
that is being a developing country it was a high time to provide the required thrust and to start
the same with a real estate industry.
Since the concept on which we are working is still in its initial phases, studying various
models on the internet was a basic part of our preliminary investigation like studying a basic
model of a automobile manufacturer using SMAC stack to engage with its customer. Then
relating the same business model to a real estate SMAC stack to identify the basic areas of
investigation. We has also taken into account certain real estate websites which would tell us
the basic idea about how a normal user searches for any real estate related enquiries. Then we
also surveyed a few people to identify the most primitive way and the sources used by a
layman if he/she intends to buy/rent/sell anything related to a property.

4.1.1 ONLINE/ONSITE OBSERVATION:
1. PropertyBase : PropertyBase is a real estate website deployed for the USA citizens
and works in finding the best possible property deals for them. The complete website
works on Salesforce platform. We have tried to make our project analogous to
PropertyBase keeping in mind the Indian requirements and Indian ways of dealing
with property. The various features which we included in our project which are
similar to PropertyBase are as follows:
a. Views are the key to accessing your data. Views are simply filtered lists of your
data in Propertybase, allowing you to specify what you want to see, and how you
want it to be represented to you in your profile.
b. Staying in touch with your contacts and providing them with the most relevant
information is key to managing a successful business. With Propertybase users are
able to send their contacts emails with listing details they think would be
interesting for them. Within Propertybase these are called Recommendation
Emails.
c. Companies are records of other businesses that you have a relationship with.
These can be leads, customers or even partner companies. Companies have a one
to many relationship with contacts. You can associate contacts to your company
records, so we can understand the individuals and their roles in the company
d. Dashboards are great way of giving your organization an overview of how exactly
the company is performing as a whole and how each agent is performing
individually with intuitive graphs and charts. At times you may find that your
Propertybase users can't see a Dashboard you have set up, well there is a little
detail that needs to be taken into consideration.
e. Reports are a key way to measure your business. Propertybase includes the power
of the Force.com based reporting suite. Using the features of this reporting suite
you can report on any object from within Propertybase.

___________________________________________________________________________
7 | P a g e
f. Email templates are used to send a standard message to your contacts. You can
enrich these templates with data from Propertybase.
g. The offer object allows you to track offers related to your listings. You can track
the amount offered, the conditions of the offer and which party has made the offer.
The object automatically tracks the history of both buyer and seller offers and
stores them in a related list on the offer record.
h. The closing object allows you to track details of the closings for all of your deals.
We have preconfigured fields to connect important individuals to your deals, as
well as a check list where you can tack progress towards tasks such as home
inspections.
i. The property object allows you to maintain a continuous record of all properties
which you have had as a listing previously. This object is primarily a background
object, but as with any Propertybase object you are able to customize it for your
purposes. The property object contains details that are relevant to that property
which will not change over time. The information which is stored there is by
default fairly minimal. You can track vital details such as address, and size.
j. The request object allows you to easily link your leads or clients to available
listings that match their criteria. The request object comes pre-configured with
common property criteria that clients look for. Once you enter a request for a
contact or company, you can press a button that will direct you to a pre populated
view of listings which match the criteria. From this screen you can easily send out
emails containing the vital details of each listing to your potential client.

4.2 PROCESS MODEL USED:
4.2.1 SELECT MODEL:
AGILE MODEL
4.2.2 ADVANTAGES OF SELECTED MODEL:
We have used the AGILE software model in our project. Our project Estate hub is
based on Real estate business and this business is changing within fraction of seconds. Hence
no other model than agile would have suited better. Agile development model is also a type
of Incremental model. Software is developed in incremental, rapid cycles. This results in
small incremental releases with each release building on previous functionality. Each release
is thoroughly tested to ensure software quality is maintained. It is used for time critical
applications. Extreme Programming (XP) is currently one of the most well known agile
development life cycle model.

7. TECHNOLOGY USED:
 Salesforce platform
Salesforce.com is the primary enterprise offering within the Salesforce1 Platform, and
provides companies with an interface for case management and task management, and a
system for automatically routing and escalating important events. The Salesforce
customer portal provides customers the ability to track their own cases, includes a social
networking plug-in that enables the user to join the conversation about their company
on social networking websites, provides analytical tools and other services including
email, chat, Google search, and access to customers' entitlement and contracts.. The Sales
Cloud includes a real-time sales collaborative tool called Chatter
 Designing – Visual Force, HTML, CSS, JAVASCRIPT
Visualforce is the view control technology on the Force.com platform. It is an
open/close tag based library with structure and markup very similar to HTML.
Visualforce can be used to create entire custom pages inside a Salesforce organisation in
conjunction with many other front end technologies, such as HTML5, CSS3 and
Javascript. One of the key benefits of Visualforce is tight coupling to native features of
the platform, such as controller methods and data access, that would not typically be
available to other front end technologies.
 Coding – APEX
Apex is a proprietary programming language provided by the Force.com platform to
developers similar to Java. It is a strongly typed, object-oriented programming language,
following a dot-notation and curly-brackets syntax. Apex can be used to execute
programmed functions during most processes on the Force.com platform including
custom buttons and links, event handlers on record creation, updates or deletions and via
the custom controllers of Visualforce pages.

9. TESTING
9.1 OBJECTIVE OF TESTING:
 Finding defects which may get created by the programmer while developing the
software.
 Gaining confidence in and providing information about the level of quality.
 To prevent defects.
 To make sure that the end result meets the business and user requirements.
 To ensure that it satisfies the BRS that is Business Requirement Specification and
SRS that is System Requirement Specifications.
 To gain the confidence of the customers by providing them a quality product.
9.2 TESTING METHODS APPLIED:
WHITE BOX TESTING: White box testing is highly effective in detecting and resolving
problems, because bugs (bug or fault is a manifestation of an error in a software) can often be
found before they cause trouble. We can shortly define this method as testing software with
the knowledge of the internal structure and coding inside the program). White box testing is
also called white box analysis, clear box testing or clear box analysis. It is a strategy for
software debugging (it is the process of locating and fixing bugs in computer program code
or the engineering of a hardware device) in which the tester has excellent knowledge of how
the program components interact. This method can be used for Web services applications,
and is rarely practical for debugging in large systems and networks).
BLACK BOX TESTING: Black box testing is testing software based on output
requirements and without any knowledge of the internal structure or coding in the program).
In another words, a black box is any device whose workings are not understood by or
accessible to its user. For example, in telecommunications, it is a resistor connected to a
phone line that makes it impossible for the telephone company’s equipment to detect when a
call has been answered. In data mining, a black box is an algorithm that doesn’t provide an
explanation of how it works. In film–making, a black box is a dedicated hardware device:
equipment that is specifically used for a particular function, but in the financial world, it is a
computerized trading system that doesn’t make its rules easily available.

10. CONCLUSION
10.1 LIMITATIONS
 Since deployed and developed using a cloud computing environment it needs 24*7
internet facility.
 Since storage of all resources is on cloud, user does not have actual control on his
resources.
 Needs a subscription to use the product which involves a cost.
 Since using cloud technologies it is prone to various security breach attacks.
10.2 FUTURE SCOPE
Since our project uses the most trending and emerging SMAC model hence it will be
wise enough to say that it has an immense future scope. SMAC is claimed to be the fifth
wave of the IT industry, and is a highly scalable and flexible model. The project can be
expanded as and when required and the same concept can be applied to diverse fields as
well.This project can further be linked with the social networking websites like twitter,
facebook, linkedin so as to attract more users who are interested in the real estate business
and who wish to buy and sell the properties online.
10.3. CONCLUSION
The absence and lack of awareness for enhancing the long standing business in our
country is the very basic intent of implementing this proliferating business model SMAC that
is welcomed with open arms by all long standing business organization across the world.
Realizing this need, we look forward to deliver above mentioned services at cheap and
affordable cost to the various industries across the country so as to initiate the thriving SMAC
global phenomenon from the real estate business domain. Henceforth the Estate HUB caption
defines our motto come let us grow together.
