1.Abstract
We have been stucked with new innovation but the main requirement is simply stuff that works.
With the present change in perspective in automated field, there is an urgent requirement to grasp
and welcome the intensity of innovation. Various challenges exist in order to manage rental
properties data as currently the organization is using manual framework. Subsequently there we
have to build up a rental properties framework that will be able to work for the managers who
can work efficiently as well as in effective way.
I understood all work was done physically using paper work. Paper work is more prone to errors,
lost or damaged. The process of managing data in manual file system is more expensive. In order
to find specific file from numerous files turns into a challenging task. Thinking about those
certainties, I have chosen to develop a rental house framework that can help the organization to
manage all processes automatically and resolve all the issues that are faced by using manual file
system. This new automated system is very easy to use or we can say it is user friendly.
(Gommans, H., P. & Njiru, 2014).
2.Introduction
The rental association having begun the business of renting properties that manage all its records
manually by utilizing the documents, books and papers which had turned out to be very difficult
to oversee because of the high multifaceted nature brought about by the persistent rise in
customer's numbers and also properties. Hence, the administration had chosen to embed new
access database framework which will be automated in the information and subtleties
management. The rental management framework is proposed to be structured by GDC
organization which is mainly into renting properties that currently manually deals with handling
data.

This report is to analyze an access project which is developed to eliminate the current issue of
the unstructured database in an association and also discusses that how this system can enable
the organization in organizing their manual database, make their performance better by
implementing modularity and advance user friendliness of the application while diminishing the
overhead expenses. The venture incorporates the making of ER diagram by implementing
relationship between various tables and referential integrity constraints by validating the
correctness of data which is stored in database. This report also includes the feasibility matrix of
various solutions that can help to choose a best one among these solutions.
3.Organization Background
In case of housing and renting organization, the significant viewpoints to be considered in the
everyday life where individuals continue searching for renting property for different uses which
could be private, business, workplaces or any type of storage purposes. The speculator will buy
and oversee the properties which are income generated for them. These properties can have at
least one units that are rented out to inhabitants in return for monthly rental charges. Financial
specialists can have a viable rental solution without having to legitimately deal with these
properties. GDC organization is planning to start renting business where the organization has to
manage all data related to vacant properties, investors, customers, and so on. It is very difficult
for them to maintain all data manually. Therefore, the organization wants to automate the entire
system.
The association had been confronting different issues when they are attempting to deal with their
properties and their client's data where the majority of them utilize the manual framework which
is repetitive, inaccurate, tedious as well as prone to errors. The administration had been taking a

Student Name
Student ID 6
lots of time while attempting to recover the stored information and therefore debilitating the
clients and landowners from utilizing their administrations.
4.Project Description
As all the processes of GDC organization are manually, they need a relational database that can
help the organization to automate all its processes. According to the organization, there is the
requirement for login form so that the authorized user can have the access to rental database with
the assigned usernames and passwords. Hence, we have developed the system which starts with
their login details only. The organization needs to move the information of the rental property
from current occupant data table into old inhabitant data whose end date comes to end. At
whatever point the user will update the occupancy status of the particular property to be
terminated, all the property's details will be deleted from current inhabitant data table and after
that it will be inserted into old inhabitant data table.
The organization needs to keep the track of the considerable number of activities done by the
users and that means any progressions that have been made by the user. Also, there is the
requirement of financial reports related to each property.
The organization needs to create a layout for the property review reports. But this was not seem
as practical as the detail for the analysis of any property will be distinctive and needs to be
clarified by the Property Manager in this report. So it was not reasonable to produce the
inspection report for each property. The project will help to display the monthly financial reports
in order to generate overall revenue. This will help the organization to have better decision
making related to properties.

5.Literature Review
Data drives the business and also helps in business decision making process. The management
decision in GDC mainly dependent on information stored. Without any comprehension of the
importance of data standards, business choices can be adversely influenced. The customers who
do not pay their rent timely are the main area of concern. The data which is provided by the
application structure by planned occupants are insufficient for making better decision. All the
statistics on renting properties (residential, business) values significantly affect family spending
and obligation, the home loan advertise, land speculation or development and eventually on
financial stability in the medium and long haul.
The successful implementation of renting property management system mainly demands
pertinent understanding, ability and appropriately using technology and authoritative abilities
just as assets to effectively maintain as well as improve property value by using obsolescence.
Property resources, which incorporate land and structures, are a distinct advantage for the
organization, that include local authorities as well as central governments. Similarly as different
assets - human, financial and data which contributes the success of the organization (Oloyede &
Ayedun, 2014).

Figure 1: Literature Map
5.1. Proposed System
The proposed framework for GDC renting system must have all the features like adding a
property, mentioning whether it is commercial or residential. Also, instead of working with non-
spatial database, the framework additionally works with spatial information. The framework will
have some more features like Specification based search, generating monthly renting report,
revenue generation report and all other accounts reports and so on. The system must enable
authorized user to add property by mentioning its location. The system will help the admin user
to search particular report on the basis of some criteria. (Mahajan, J. & Mahajan, 2016).
5.2. Data Gathering Techniques
We have used three methods for gathering data and understanding all requirements and these
include - observation, interview and references.

Student Name
Student ID 9
I. Firstly, we have observed all the current documentation like daily account books, properties
records, renting records and so on.
ii. Perception as the data collection method was utilized to know how the current framework was
being utilized ideal from when a property is rented, various forms that are filled while renting
commercial as well as residential property and also the time taken by the admin to prepare all the
reports. This accumulated information and data that would not effectively be gathered by various
methods.
iii. The third method which we have used is to interview main users who helps in making a
renting successful. The main points which were asked include challenges that they were facing
while renting a property and how they make data secured. (Akomolafe & Timothy, 2014).
5.3. Options for Developing System
5.3.1. Option 1 - Using Online System Architecture (Web based)
The online web application for GDC renting system can be developed using .NET web
application utilizing ASP.NET and SQL 2008 by utilizing C# programming language. This
infrastructure will be based on client server architecture which is based on HTTP protocol. This
application will be developed in the environment of Microsoft’s Visual Studio .NET. Despite the
fact that ASP.NET takes its name from Microsoft's old web advancement innovation. Microsoft
has totally revamped ASP.NET dependent on the Common Language Runtime (CLR) shared by
all Microsoft .NET applications. The coding can be done by ASP.NET code utilizing any of the
diverse programming language upheld by .net system which can be Visual Basic .NET,
Jscript .NET, C#.

Student ID 10
Figure 2: Architecture of Online Application
The main limitations of above development process are – lack of funds, more time required for
development process, property can be visible for some time only, the complexity of coding,
difficulty to embed backend database in front end coding and so on. Different servers will be
required to run an online application. Also, in terms of security, database will be less secure as
data is more prone to be hacked. Therefore, additional security measurements will be required to
provide additional security to the database (Kirmani & Yousaf, 2017).
5.3.2. Option 2 – Customized ERP System
In case of customized ERP system, the entire processing is divided in three layers - Presentation
layer, Application layer and Database layer. The Presentation Layer contains the all the
components or subsystems of the system that make up the SAPgui (graphical UI). This layer acts
as the interface between the R/3 System and its clients. The R/3 System uses the SAPgui to give
a natural graphical UI for inserting as well as for updating the properties details.

Student Name
Student ID 11
Figure 3: Architecture of ERP Solution
The Application Layer consists of one application servers and the message server. Every
application server consist of various services that will be required to run R/3 system. The
message server mainly communicates with the application servers.
On the other hand, the Database Layer comprises of central database framework which consist of
all the data in the R/3 System. It consists of two segments - the database the management system
and the database. The database consists the control and modifying information that decide how
R/3 System runs. Applications comprise of program code, screen definitions, menus, work
modules, and different parts. These are stored in the R/3 Repository which is a special segment,
and are appropriately called vault objects. (Guru99, 2019).
But implementation of customized ERP is an expensive affair and time consuming. Also, high
support and maintenance cost will be required to manage ERP system. A team of highly skilled
staff will be required to manage ERP system. Also, it will take time to troubleshoot any type of
error in implementation process.

Student ID 12
5.3.3. Option 3 – Developing System using MS Access
A Database Management System (DBMS ) is fundamentally a accumulation of projects that
empowers a user to embed, change, retrieve information and subsequently make it simple to
configuration, maintain as well as access databases. The DBMS diminishes the user from
knowing how the information is stored physically and complex algorithms utilized for
performing various operations on the database. It just concentrate on how the tasks are to be
performed to recover the information from the database. MS Access is one of the choices that we
can use for this reason. By utilizing the program and great storage device, we can make a
tremendous market Access land and property database and store it into the Access database.
(Prabhjot & Sharma, 2017).
Microsoft Access is the best database engine that can be used for developing the bespoke system
that can be implemented easily. The inbuilt wizards in MS Access helps the organization to
develop application very easily and also accelerate the development process, and a huge range of
promptly accessible functionality. Only half of development time will be used for developing the
system than required for developing system using other alternative options. This is best
advantage that MS access has. It makes an interpretation of legitimately into a cost-putting
something aside for us and it implies that pivot times are typically a matter of half a month from
beginning through to the delivery time.

Student ID 13
Figure 4: Architecture of MS Access
Also, it is very easy to update any type of data in MS Access. Access and its VBA programming
language are known by numerous software developers, developers and programming
organizations. This implies in the event that we make a framework utilizing MS Access, we
won't be screwed over a single person who made it for you. (Software-Matters, 2019).
The data which is residing in data store can be recovered through the information supplier.
Various components helps to retrieve information for the application and update information. An
application can access information either through a dataset or an information peruser. Datasets
store information in a detached reserve and the application recovers information from it. Data
readers helps to give information to the application in a read-only as well as forward-only mode.
DataSet is an in-memory portrayal of information. It is a detached, stored set of records that are
recovered from a database. At the point when an association is built up with the database, the
information connector makes a dataset and stores information in it. After the information is
recovered and stored in a dataset, the association with the database is then closed. This is known

Student Name
Student ID 14
as the 'detached architecture'. The dataset functions as a virtual database that consist of tables,
rows and columns. On the other hand, data provider is utilized for associating with a database,
executing directions and recovering information, then store in a dataset, perusing the recovered
information as well as update the database. (TutorialsPOnt, 2019).
5.4. Recommended Solution

From the feasibility matrix provided above, it is clear that MS Access is best option for the
organization to develop the application. The benefit analysis is provided as following.
5.5. Benefit Analysis to the Organization
The Organization: A database can help to provide the structure to entire business processes. It
will help to automate all the processes of the organization.

Student Name
Student ID 15
Information Validation: A database permits organizing rules for data entry like proper rules
should be defined before data entry.
Effectiveness: Databases reduces the requirement for the redundancy in data entry that is
commonplace of spreadsheets.
Information Security: The database applications are more secured as compared to the
spreadsheet as client access into the framework and limitations on access to the information that
is perceptible.
Reporting – Simple, detailing is significantly more vigorous from a database where different
records for a solitary client or dataset can be immediately created. The database will help the
users to view all types of desired reports. Reports can be based on particular criteria
Sharing Data: Many database users are able to access a similar record and information at the
same time. In this way, no file duplication exists, singular client alters and organizing clashes
that are normal with spreadsheets. (Ebsen, 2016).
Cost-effective - The other main reason for MS Access to be better choice as it is less expensive
as compared to other options. As compared to large database structures, MS Access does not
require a major measure of maintenance cost. This for all intents and purposes free database
system is considerably more efficient and essentially reasonable as compared to other options.
Simple Programming - Access database has a simple to-utilize program that makes database a
very easy system. With the utilization of basic code, we can systematize the tedious errands
which some are pre-constructed prepared to apply. The element of VBA (Visual Basic for
Application) empowers end-clients to make progressively many-sided and responsive code
systems without including more efforts.

Student Name
Student ID 16
Simple Integration - Databases which is built in MS Access can be sent out without trouble to
other Microsoft Office applications. Microsoft Access 2016 uses standard language to do all
other operations that are rapidly comprehended by other programming programs in Windows.
For instance, information made in Microsoft Access can be opened and altered in MS Excel as
well. (Benad, 2017).
5. Development Process
1. Data Analysis - This part i.e data analysis starts with the data requirement and afterward
delivers a theoretical information model. It helps to provide detailed analysis of the
organization’s data that will be according to the client necessities so both high as well as low
dimension rental properties and their utilization are managed. These incorporate properties like
various values that can be allowed for defined attributes. The conceptual data model helps to
provide a mutual, formal portrayal of what is being imparted among customers as well as
developers during database development process – it is based on the data in a database,
autonomous of the usage of that data in customer processes or execution of the information in
computer environment.
2. Logical Design - Database configuration begins with a theoretical information model and
creates a logical schema; this will decide the particular sort of database framework (organize,
relational, object oriented) that is required. This is yet autonomous of a particular DBMS; it is
another conceptual information model. Here, we have used relational approach for developing
conceptual data model. The output of above schema is the detailed specification of entire tables
as well as constraints that are required to develop data model. All the choices related to attributes
and tables will be based on adaptability for change, redundancy control.

Student ID 17
Figure 5: Conceptual Map
The above figure outlines the iterative steps that are associated with the configuration of
database, in perspective on the ER diagram. Its essential explanation behind existing is to
perceive the general issue of what tables should be used from the itemized importance of the
segments of each table. These tables are seen as one thus, regardless of the way that they are not
free of each other. Each accentuation that incorporates a change of the tables would incite
another structure; they are typically suggested as second-cut plans, paying little respect to
whether the method underlines for more than a single loop.
Implementation Process - The implementation process includes the development of a database
as indicated by the particular of logical schema. This will incorporate the detail of data storage
schema, security authorization, external outline, etc. Usage is intensely affected by the decision

Student Name
Student ID 18
of accessible DBMSs, database tool as well as operating environment. There are extra errands
past essentially making a database outline and executing the imperatives – information must be
gone into the tables, issues identifying with the user processes that needs to be addressed.
Understanding the Design - After the coherent plan has been made, we need our database to be
made by the definitions we have created. For an execution with relational DBMS, this will most
likely include the utilization of in build GUI to make tables as well as constraints that will help to
fulfill the logical depiction and the decision of suitable data storage mapping .
Populating the Database – There are many ways in MS Access to populate tables, but we will
use importing data from MS Access. By importing, it means to copy excel data into the tables by
just selecting few options. (Watt, n.d).
Tools Used
The main tools which were used in the development of system are given as following:
S. No Tool Used Use
1. MS Visio Creating ER and other UML Diagram
2. MS Access Creation of database structure
To create macros
To create VBA coding for creating forms
3. MS Word To create documentation part
4. MS Excel To create time log
6. Microsoft Outlook Communicate with employees
5. Microsoft Teams Communicate with employees
6. Zoom.Us Communicate with employees
6.Supervisor Evaluation of the System
The main role of supervisor is to add new users on the basis of their privileges. He is the person,
who will be responsible for analyzing all finances by retrieving all the finance reports on the
basis of particular criteria. The supervisor is quite satisfied by the new system, as all the reports

Student Name
Student ID 19
can be printed directly from computer without taking much time as the response time to retrieve
the data from database is just few seconds. He can easily generate revenue by analyzing
expenditure as well as the profit gained by analyzing the reports.
Also, he can easily insert the property details with the location and specification and also will be
able to manage customers data. Whenever a new customer comes at GDC office, the supervisor
will be able to check all the vacant properties according to the client requirements. He can use
particular criteria to retrieve all properties. Whenever client makes ok, for a particular property,
the supervisor enters all the details of the customer and make that particular property rented with
all financial details like monthly rent and so on. The system will also enable supervisor to add
lease period by completing all the formalities.
7.Client Evaluation on the System
An organization can grow only when it has satisfied customers. The main responsibility of client
is do all the formalities for a renting a property whether its for business purpose or residential
purpose. A client can only be satisfied if all his requirements are fulfilled by the organization in a
very short period of time. The system will help the organization to satisfy the customer as all the
processes will be completed within a short time period. All the details requested by client can be
retrieved in a very less response time.
8.Deeper Analysis
Whenever a properties comes at GDC organization for renting purpose, all the details are entered
into the system by supervisor. He is the person who is responsible to enter all specification of the
property so that particular property can easily be retrieved. The renting system can be utilized as
the inventory framework in order to enable supervisors to make sensible transactions in just few

Student Name
Student ID 20
minutes outline. Each transaction made on the framework go connected with the information
that is regularly updated in the database.
Things that went well
The successful execution of the new framework will simply upon the inclusion of the supervisor.
The system can only be successful when proper training will be provided to all users. This
training will help the organization of the data flow, screen flow, type of screens where they have
to input the data and the errors that they can face while operating this system. It should then
cover data required by the particular client or group to utilize the framework. (Gommans, H., P.
& Njiru, 2014). The development team has proper skills that helped them to develop the system.
They used agile development methodology which is plus point for the project. Also, as the team
used agile methodology, the overall project is divided into small sprints, that helped the
developer team in application development. Therefore, each part of the project is planned
accordingly. The schedule time was sufficient for developing this system. All the tools that
required to develop the system can easily be downloadable from net.
Things that didn’t go well
There is the requirement of documentation of entire project processes including coding which is
missing from project implementation. Also, during implementation of project, there was lack of
internal communication of the stakeholders which was main drawback of the project. The
hardware used in the organization was not up to date because of constrained budget. Also, the
developer didn’t have the sufficient coding and texting skills.

Student Name
Student ID 21
9.Limitations Discussed
As an intern at GDC, various limitations exist in the development process while developing
application for GDC. I faced a lots of challenges in overall development process. The first one
was to develop an application in very short time period which was approximately five months.
Being intern, less resources were provided by the organization in order to develop an application.
This is my first project and it was great responsibility on my shoulders. And because of limited
skills and knowledge for developing a system it was very challenging task for me. Also, because
of lack of knowledge about agile or waterfall methodology, I took simple development method
for developing renting system. It was very challenging to secure the database as not much
options exist to secure database in case of MS Access. Therefore, I used authorized user
privileges for securing the database, so that only authorized users can access the system.

11. Conclusion
The database system can be utilized by GDC in order to maintain properties, customer details
and can enable the managers to make better transactions set aside a few minutes outline. All the
transactions that are made on the framework go connected at the hip with the information being
updated which we have utilized MS Access. By utilizing Management Information Frameworks
which expect to help managers to make decisions more effectively through quick access to
applicable data. The project of GDC renting system, is intended to fulfill the necessities of rental
house proprietors. Various user friendly interfaces have likewise been adopted in order to make
it easy to use. This system will help to be an incredible in fulfilling all the prerequisites of the
users. The system will help the organization to manage all the challenges related to data handling
and urge you to keep acknowledging innovation since it is intended to change furthermore,
facilitate all our work that is by all accounts exceptionally difficult. We have considered three
options for developing the system for the organization. The alternative solution which we have
chosen in order to automate the processes of GDC is MS access because of its user friendly and
easy to use properties. The choice has been made on the basis of feasibility matrix.
