|M1 Identify and apply strategies to find appropriate solutions||· Complex problems with more than one variable have been explored|
· An effective approach to study and research has been applied
§ Evidence has been given that the student has a good understanding of database theory and the issues related to it.
|To achieve M1, you must demonstrate|
|M2 Select/design and apply appropriate methods/techniques||· Relevant theories and techniques have been applied.|
· A range of methods and techniques have been applied.
|To achieve M2, you must demonstrate|
|M3 Present and communicate appropriate findings|
· A range of methods of presentation have been used and technical language has been accurately used
· The communication is appropriate for familiar and unfamiliar audiences and appropriate media have been used
|To achieve M3 you must produce :|
|D1 Use critical reflection to evaluate own work and justify valid conclusions||To achieve D2 students must provide:|
|D2 Take responsibility for managing and organising activities||To achieve D2 students must show that|
· Work is well organised and well-presented and has been completed within the allotted time span. This can be evidenced through the completion of a high quality report delivered on time.(Task 3b)
|D3 Demonstrate convergent/lateral/ creative thinking||· Ideas have been generated and decisions taken|
· Innovation and creative thought have been applied
To achieve D3 students must show that:
The system has been extended sufficiently and creatively, and this has been implemented correctly i.e. more tables, more queries , more input forms and reports should be added sufficiently and creatively while not affecting the existing system.(Task 6)

Purpose of this assignment
This assignment considers the skills required to perform effectively as a Database design and development employee. To give learners opportunities to develop an understanding of the concepts and issues relating to databases and database design as well as the practical skills to translate that understanding into the design and creation of complex databases.
You have got a database design and management company called Best Solution Database Ltd. Your client Events R Us – an event management company wants Best Solution Database Ltd. to create and maintain their employee’s database to maintain details of its employees’ project area skills. According to the client’s requirement:
Each employee can be identified by their unique employee number/id, employee name, employee grade and which department they come from. As per the client’s requirement each employee may work in many projects but must not belong to more than one department.
Each department can be identified by a unique department code, department name and types of job. Department code is different for different types of jobs(e.g. Department codes are different for HR department and Marketing department).
Employee’s database should store details of job assignment for each project. Each job assignment will show which project is being done by whom/which employee.
Each project should be identified by unique project code/number and project name, project budget , project type(e.g. long term, short term, overseas etc).
You as an employee of Best Solution Database Ltd are required to provide the design and implement the same design to produce a fully functional database system to help Events R Us to carry out its tasks efficiently. Read more about : Research on Development Project Assignment Help
You should concentrate on the core function and not try to implement support functions such as finance and human resources except where they are directly related to the core activity or to an extension task.
Task 1 : (LO1 & LO 2: P1.1,P1.2,P2.1,P2.2,Part of M1, Part of M2,Part of M3)
a) State the various employment roles that will be available in ‘Best Solution Database Ltd.’ as a result of creating the employee database system for Events R Us.
b) Discuss how ‘Best Solution Database Ltd’ will deal with problems relating to integrity, security, recovery and concurrency while creating the employee database system for Events R Us.
c) State and describe the advantages and disadvantages of relational databases over paper based systems and flat file systems what Events R Us will have after introducing the new employee database management system.
d) Prepare a presentation and provide the print out of the slides based on the following concepts:
iii) key fields,
iv) foreign keys to build relationships,
v) compound keys
vi) many to many relationships
vii) the three level(ANSI SPARC) architecture for the DBMS
viii) different use of databases in the real world .
ix) popular database models that are used in real world
x) the need for Database Management Systems (DBMS)
e) Based on the given scenario describe the process of Normalisation (with diagrams) up to 3NF (i.e. UNF,1NF,2NF,3NF).
f) Provide ERDs for UNF,1NF,2NF,3NF with explanation.
Task 2: (LO 3: P3.2, Part of P3.1, Part of M1,Part of M2)
a Design an appropriate database for the given scenario. The design documentation must include:
· An entity relationship diagram (3NF stage only) with correct cardinality in MS-ACCESS.
· A data dictionary specifying the structure of all the tables.
· Design of the tables, input forms based on ERD
· Designs of at least four complex database queries and four database reports that could be used by the organisation as described by the scenario. All reports must be created from complex database queries.
|Task 3-a) (LO 3: Part of P3.1, Part of M2)|
Implement the design and provide evidence of the implementation. via annotated screenshots and source code. Create all the required tables, forms, queries and reports. Include data validation methods where appropriate.
Task 3-b)(LO 3: . Part of P3.1, Part of M2, D2 )
Test the system using an appropriate test plan and test data,test report. Amongst other things testing must demonstrate that entity integrity, referential integrity and data integrity has been enforced and relevant reports have been developed successfully
A high quality report must be delivered on time for D2.
|Task 4 (LO 3: P3.3 ,D1)|
Evaluate the effectiveness of the database solution and suggest methods for improvement.
A very strong evaluation must be provided for D1.
|Task 5 (LO 3: P3.4, Part of M3)|
Create a user manual of the developed system (contents page – introduction – step by step instruction to use the system accompanied by relevant screenshots).
|Task 6(LO 2 and LO 3: D3)|
Realistically extend the given scenario and add other functions that could be implemented into the database system. Extra tables must be correctly added to the system along with supporting queries and reports.
