Database Development Cycle and Implementation: A Detailed Report

This report provides a comprehensive overview of relational database design and implementation. It begins by defining database concepts, security, advantages, and organizational issues. The report then delves into database design methods and methodologies, focusing on logical design, requirement specifications, and development areas. Normalization techniques, including 1NF, 2NF, and 3NF, are thoroughly explained, along with entity-relationship (ER) modeling. The practical aspect involves designing a fully functional database with inter-relational tables, demonstrating SQL queries for data manipulation and extraction. Finally, the report addresses data verification and validation techniques, presenting test cases and user/technical documentation to ensure database effectiveness and usability. This resource is available on Desklib, where students can find a wealth of similar solved assignments and past papers to aid their studies.

Introduction
Relation database is a collection of the information and records. It stored the data in the tabular form
which can be an update, access, insert, delete, and selected the database. Database supports for data
verification and validations, and data normalization. Here, I have created the database on the MS Access.
Database report divides into three parts.
In the first section, I will define database concept, database security, advantage and distance. The
database will explain organisational issues. I will also explain Database design methods and
methodology. In the second section, Logical design, requirement specification, and development area will
be explained for the database. I will also design the normalization and ER diagram for the database. In the
third section, I will design the database and performed the query on the database. Further, I will define
the data verification and validations techniques and designed a user and technical documentation.

2.2 discuss entity-relationship modelling and normalization
Normalization:
The database is a collection of information. Database use normalization to reduce the data redundant in
the database table and improved the data integrity, efficiency, and scalability. Relation methods and
model explained the efficiency of the database which is classified in the normal form. Normalization spilt
the database table into a normal form that must be re-joined the table according to the query (Memon,
2014).
First Normal Form
It referred as 1 NF which contained following specification
 Each table attribute should be a unique name which contained a single value.
 The table cannot contain row duplicated value.
 In the 1NF does not allow the repeating groups.
Here, I have shown 1 NF for database

Second Normal Form
It referred as 2 NF which contained following specification
 2 NF table must be in the 1NF form.
 2NF remove the partial dependencies and designed another table.
 It is fully dependent on the table primary key
Here, I have shown 2NF for database

Third Normal Form
It referred as 3 NF which contained following specification
 3 NF table must be in the 2NF form.
 It removed the transitive dependencies in the table which means table Non-primary attributes
independent from other Non-primary attributes of the table (Saokosal, 2015).
Here, I have shown 3NF for database

Entity-relationship modelling
ER modelling is creating a graphically representing the object and their logical relationships in the
database. ER diagram design with objects and their relationships. Objects or Entities represent by the
ovals, polygons, points and circles. The relationship represents a line which connected the objects. It has
an equivalent relational database table and vice-versa. It used for the design of the database, debugging,
and optimization. It defined one to one, one to many, many to one and many to many relationships in the
database (Inf, 2000).

3.1 apply the database developmental cycle to a given data set
Relational Database
A relational database is a collection of data which represented in the tuples or table form. It commonly
used the database.RD is contained a number of table in the database and each table has a primary key.
Data access form RDMS easy compare than other the database table. The relational database supports
MYSQL, SQL, and So-on another query language that used extract the information or data from the
database.
A feature of the relational database:
 Data is stored in the tabular form which contained the primary key in each table.
 It defined the relationship between the table.
 ACID property support by the Relational database. ACID means Atomicity, Consistency,
Isolation and Durability.
 It is a centralized database which supports the normalization
 RD objects contained complex relationship.
 A relational database is supported the transaction and update tool (Aslam, 2016).
