Overview of business case:

A&H Boating is a small start-up company that sells small boats in Geelong. A&H Boating keeps its models in several showrooms across the city. At this stage customers cannot view the available models online so to order they must visit one of the showrooms. A&H Boating has been using an Excel spreadsheet to track their business activities, however, this has caused many redundancies and inefficiency.
With view to their expanding business and under the new management, they decided to investigate the option of implementing a database system. Accordingly, they hired you to design a relational database to better track and record their operational data.

A&B business rules and instructions for creating your ERD:

1. A&H Boating can get boats from several different manufacturers. Each manufacturer produces one or more different types of boats. Each and every type is produced by only one manufacturer. Every manufacturer is identified by a manufacturer code. The company name, street, city, state, postcode, phone number, and account number are kept in the system for every manufacturer. For each type, the type name (i.e. Paddle, Inflatable, Jet Ski, etc.) and purpose (i.e. fishing, day boating, etc.) are kept in the system.
• Create an ERD that represents the entities, attributes, the relationships between entities, and the cardinality and optionality of each relationship that are described by this business rule.

2. Every type has one or more models. Every model is produced as part of a type. For each model, the model number, engine, length, beam, suggested retail price, retail price and dry weight must be kept in the system.
• Add the entities, attributes, relationships between entities, cardinality and optionality of each relationship that are described by this business rule to the ERD that you created for business rule 1.

3. Each type’s models are stored in a specific warehouse. Each warehouse stores the models of only one type. Each warehouse is identified by a warehouse ID. For each warehouse address, postcode, phone number are kept in the system.
• Add the entities, attributes, relationships between entities, cardinality and optionality of each relationship that are described by this business rule to the ERD that you created for business rule 1 and business rule 2.

4. Each warehouse can be visited by prospective customers with prior booking. Customers can book a visit to a specific warehouse by calling A&H Boating hotline. Customers need to provide full name, date of birth, address, email address and contact number during booking a visit to a warehouse.
• Add the entities, attributes, relationships between entities, cardinality and optionality of each relationship that are described by this business rule to the ERD that you created for business rule 1, 2 and 3.

Rationale

This assessment item is designed to test your understanding of the following learning outcomes:
• Basic database design and modelling concepts,
• Identification and interpretation of business rules,
• Creation of an Entity Relationship Diagram from a set of business rules,
• Application of correct relationships, cardinalities, optionality using the Crows Foot modelling notation.

A&H Boating company 1
Task 1
Business rule 1: - this business rule says that A&H boating company can get boats from several different manufacture companies. Each manufacture company has one or more boat type. The manufacture company uniquely identifies by the manufacture id and this database also store manufacture companies related information. This information is related to manufacture name, company name, company street name, company city name, company state name, postcode, company phone number or contact number and account number of company. Every boat type uniquely identity by the boat type number and database also store boat type information. This information related to the boat type name and purpose of boat type.
ERD: - this entity relationship diagram creates according to using the Crows Foot modelling. This ERD have entities, attributes, relationships, primary keys, foreign keys, cardinality and optionally.
· Entities: - according to business rule 1 this ERD contains two entities. these are following: -
1. Manufacture entity.
2. BoatType entity.
Manufacture entity: -
· Attributes: - Manufacture entity have many attributes and these are following: -
1. ManufactureCode.
2. ManufactueName.
3. CompanyName.
4. Street.
5. City.
6. State
7. Postcode
8. Phone
9. AccountNumbe
· Primary keys: - Manufacture entity has ManufactureCode primary key.
· Foreign keys: -Manufacture entity has no foreign key.
· Relationships: - according to business rule each Manufacture Company manufacture one or many boat type. So we can say that Manufacture and BoatType entities have one to many relationships.
· Cardinality: - each manufacture company manufactures one or more boat type.
· Optionally: - optionally shows inside the cardinality. There are many type of optionally and these are following: -
· Mandatory: - one manufacture company manufactures at least one boat type and...
