LO3 Test the system against user and system requirements.
LO4 Produce technical and user documentation
Assignment Brief and Guidance:

Assignment scenario
You are employed as a Database Developer for a large IT consultancy company. The company has been
approached by FPT Shop which is expanding due to the growth of the number of stores. FPT Shop is currently
facing difficulties in dealing with managing the database from all shops on over country. It decided to develop a
new database so that: users can register with their phone numbers as IDs and order or rate, comment for
their bought devices, shop managers can take care for their stores and director board can view all data

from all shops.
You are tasked to select one of those systems to develop database for FPT Shop. Your tasks are to:


Work with FPT Shop to find out about current requirements for each system



Analyse the requirements and produce clear statements of user and system requirements.



Design a relational database system using appropriate design tools and techniques



Develop a fully functional relational database system, based on an existing system design.




Test the system against user and system requirements.
Produce technical and user documentation

Part 2 (Assignment 2)
Once the designs have been accepted by your manager you have been asked to:
Develop the database system using evidence of user interface, output and data validations and querying across
multiple tables.
You want to include more than just the basics so you will implement a fully functional database system which
will include system security and database maintenance features.

You have decided to implement a query language into the relational database system. The developed system will
be demonstrated to your manager.
Your manager has asked you to include in the report:
(1) Assessing whether meaningful data has been extracted through the use of query tools to produce appropriate
management information.
(2) Evaluating the effectiveness of the database solution in relation to user and system requirements, and suggest
improvements.
(3) Once the system has been developed, you will test the system and your manager will complete a witness
statement indicating how your tests are performing against user and system requirements.
(4) You will produce a brief report assessing the effectiveness of the testing, including an explanation of the
choice of test data used.
(5) Lastly you will produce technical and user documentation which will be given to the company.
You want to provide some graphical representations for ease of reference in the technical guide, so you have
decided to produce a technical and user documentation for a fully functional system, including diagrams showing
movement of data through the system, and flowcharts describing how the system works.

ASSIGNMENT 2
Introduce
In this project, an FPT shop system database was implemented on SQL server using query language. This
database enables for the modification, deletion, and insertion of important information to manage the
shop, such as customer personal information, staff information, login, product information, bill
information, bill's detail information, and rate. It is also equipped with data to assist administrators in
managing and monitoring the library's status. A comprehensive mock-up, as well as a relational database,
has been developed and exhibited here. Bugs are also fixed by testing. Finally, a technical manual based
on the mock-up was created to help users in utilizing the system.

2.2 Queries to UPDATE data with illustrations of final result
I attempted to update the data in various database tables to see if the update function worked. Users can
update data with the syntax “UPDATE table_name SET column1 = value1, column2 = value2,…WHERE
condition”. The following are the results of my testing using three database tables.
