MN405: Database Design and Implementation for Workshop Management

This assignment focuses on designing a database for workshop management, starting with identifying entities like Workshop Details, Duration Details, Participant Details, and Room Details. Attributes are added to these entities, and business rules are defined to establish relationships between them. Functional dependencies are determined, and the tables are normalized to 3NF, with each step explained. An entity-relationship (E-R) diagram visually represents the database structure. The model is then built using MS Access, populating tables with data, and SQL queries are written and executed to retrieve specific information. The assignment provides a comprehensive approach to database design and implementation for workshop management.

1. Questions
a. Analyse the all user requirements given above, identify and list all
entities described in each user requirement.
There are number of entities which can be outline from the case scenario. The list entities deduced
are:
According to user view 2
Workshop details are stored with name, id and organiser who organises the workshop. Each work
can held for maximum 2 days. Duration of work shop is stored under different entity.
1. Workshop_details (storing the workshop details along with the oraganiser)
2. Duration_work_details (The time to which workshop will be carried out)
According to user view 3
There are participants who can sign up to work with personal details with email address, state,
name.
3. Participants_details (storing details of participant if the participation has attended nay
previous session)
According to user view 4
Each work is held in different rooms at each floor
4. Room_details (storing room and floor location of workshop)
Add attributes to these entities and represent these entities (or Tables) and
attributes as a collection of Tables and attributes/ database schema.
1. Participants_details (participantID, participantFName, participantEmailAddress,
participationState, participationLName, participationPreviousSession,ID)
2. Workshop_details(ID, workshopName, Organiser_ID, orgName, orgContact)
3. Duration_work_details(ID_duration, workID, days)
4. Room_details(floor_no roomNo, workID, room_date)
3

Outline all business rules that describe relationships between entities
You can make assumptions to create certain relationships, if it is not
specifically mentioned in the given business rules.
1. Each work shop is organised by the oraganiser.
2. Each participant is indulged in one or many workshops.
3. Each Workshop is organised by only one organiser.
4. Floors can have same number of rooms
5. Each room can have more than one workshop.
Determine the functional dependences.
Figure 1: Functional dependency
4

Then normalise these tables. Make the normalization to 3NF. State for
every step in the normalization, which functional dependency causes it.
1 NF
Figure 2: 1NF
There is no inconsistency present in the tables and all the column names are unique and there is no
redundancy in the tables hence the table are in 1NF form.
5

2 NF
1. The tables needs to be in 2 NF, is required to be in 1 NF first.
2. There should not be any partial dependency
Figure 3: 2NF
6

3NF
It is required to be in 2NF, to get reduced to 3NF.
Since there is no transitive dependencies exist in the tables, hence the tables are in 3NF.
Figure 4: 3NF

f. Represent the structure of your database visually by using the
entity-relationship (E-R) diagram. If you make any assumptions
about data that doesn’t show from the problem, they must be
described
Figure 5: ER diagram
Assumptions
 Particular organiser can organise a particular workshop
 Participants can participate in more than one workshop
 Each room can have more than one work shop
 Each workshop can be continuing for more than one day.
 Each floor can have same room number

2. Build this model using MS Access by creating these tables and
Relationships. Populate these tables with appropriate data, at least 3
records in each table
