In this paper, you are required to implement the ER model provided, you must create all the relations in a Microsoft Access database, also create appropriate relationships, review the default index and populate the database with sample data of your own. Furthermore, you are to create queries to answer the mentioned information requests and finally, present a clear report.

For your help, anexample for a Student relation’s 3NF justification has been provided below:
2 Relational databaseimplementation
Note: Use the relations that you created in the above step 1-Normalization to create a database. The recommended tool for this work is Microsoft Access, version 2010 or later. One reasonfor recommending Microsoft Access is that your unit lecturer/tutor will be able to provide adequate support to you in the use ofthis tool.IfyouchoosetouseadifferentDBMS,thenthereisnoguaranteethatyourlecturer/tutorwillbeableto provide enough support to you. The remainder of this document assumes that you are usingMS-Access.
In implementing the ER model provided, you must complete the followingtasks:
Dataintegrity
You are required to implement integrity constraints within the database to enforce thefollowing requirements:
Informationrequests
Create queries to answer the following information requests. Note: Do not use the Access querybuilder (QBE) to create your queries – you should type the queries manually using SQLview/editor.
Themarking process of the queries for information requests may also consider the effectivenessofyourSQL statements that have been used in the queries.ItisimportantthatyourSQLstatementmustreflectthe correct business logic & SQLsyntax.(Use enoughsampledataso that the output is produced by each and every query).
Note: The word ‘name’ is a reserved word in MS Access. Wherever you use it for SQL query, youneed to put a bracket like [name]. Follow the same technique for other reserved words too.
