Introduction
Here we will design a database system for the VET solution of Cambridge. It is the veterinary
company that provides services and care for the animals. As the company is growing and has more
information to handle and update they require a much stronger database system for storing
information and altering or updating it on daily basis. The database would also help them to
communicate the information in a much better way. Therefore they asked to build a database for
the same, and it will be done using MS SQL 2014, that gives the best management authority to the
company. In this report, we will design the procedure of database, development and a proper
testing so they can update it on daily basis.

LO1 Use an appropriate design tool to design a relational database system for
a substantial problem
P1. Design a relational database system using appropriate design tools and
techniques
To create a database for VET Solution Company we first have to design it appropriately with all the
minute details included. This will be done using the designing tools which help in making the ER
diagram of the entities present in the company. With the growing branches of the company, it
becomes more necessary for them to have a proper database management system. With the day by
day increase in the staff and customers, creates a problem for handling data manually so they
decided to go for database management. They require adding and altering the staff details, patient
details etc for all the branches of a single database system (Coronel, and Morris, 2016).
What is the role of database management systems?
These are the software that allows the storage, retrieval, adding and deleting data. They are helpful
in performing modifying functions, organizing the given data in the user desired format. This makes
the task easier and maintenance of information and usage becomes easier. This also helps in
accounting and calculation processes. The records are easily maintained and transferred from one
place to other. In addition to this the problem of managing files is reduced (Witkowski, Dorman, and
Greenfield, 2014).
What are the user requirements?
 The database should be able to alter the information added to it.
 The database should record all the details of the pets and manage them as needed.
 It should not only cover the details of the pet but also the pet owner.
 The database should have all the information regarding the staff working in the company.
 It should be helpful in managing the invoices given for the treatment of pets to the pet
owners.
 It should have a section for all the prior appointments taken in all the clinics.
 It should also add the details of the treatment and diagnosis done to treat the patient and
what medicines or prescription was given and by whom it was treated (lechaamwe.weebly,
2017).

To fulfill all the above requirements we need to build a fast performing management system that
has appropriate data and works effectively and is user-friendly. For better efficiency, it should have
distinctive identities for the name, contact address, color and other details. For designing such a
system we require a 64-bit processor, storage or hard disk of at least 2 GB, high RAM speed, and a
good resolution display. Also, we require a user-friendly operating system such as Windows, A MS
SQL server, and tools like draw.io for making ER diagrams (Charron, Gilbertson, Konik, et.al, 2017).
ER diagrams:
It stands for entity relationship diagrams. It is basically a connection between several different
entities represented using flowcharts and shapes. For this, we need to find all the entities from the
given data first and then the connection between them. Also, there are several attributes for a single
entity, which defines the characteristics of that entity (1keydata, 2017).
The entity is a group of objects having similar characteristics that is, identified by an organization as
having a liberated existence. They can be said as the main headings of any given data under which
we have several subheadings known by attributes. Every entity has specific characteristics called an
attribute.
There is a relation among the entities which is known as a relation. The relation can be of different
cardinality ratio that is one to one, one too many, many to many (Pejathaya, Talluri, and Bhide,
2017).

M1 produce a comprehensive design for a fully functional system which includes
interface and output designs, data validations, data normalization and data
dictionary.
Data validations:
It is a process for ensuring that the data inserted is correct and no unrequired stuff is added to it, this
is a data cleansing process to ensure a good quality of data. It improves the performance of the
database system. It is of different types:
 Authentication of data type
 Authentication of code
 Authentication of constraint
 Authentication of the structure.
Design view of tables:
Comprehensive designs of the database made using SQL are as follows:
