Step by step
Solved in 3 steps
- Use normalization to decompose a relation with anomalies into well-structured relations?Based on the above Relations/Tables, write description of violations of each of the 3-constrains in the table given below: Just answer without explanation please.Given the Relational Model Notation below, extend it to defineUNIQUE and NON-UNIQUE indexes for relations.
- Give some instances of relations (tables) that may have more than one candidate key in their structure.Why is normalization useful, given that EER conversion will typically lead to a normalized set of relations?Are the tables normalized? If so, can you explain how and why your logical (relational) model is in first, second, and third normal form in relation to the question specifically?
- Normalize the following given data to 1/2/3 NF. State the relations schema after everynormalization.Discuss the differences between the candidate keys and the primary key of a relation. Explain what is meant by a foreign key. How do foreign keys of relations relate to candidate keys? Give examples to illustrate your answer.Create a relational model with foreign and primary keys
- Convert the model into relations and normalize.Use a suitable example to provide a thorough description of the relational model.Use the technique of normalization to validate the structure of your relational schema. Demonstrate that each of your relations is in third normal form (3NF) by displaying the functional dependencies between attributes in each relation. Note, if any of your relations are not in 3NF, this may indicate that your ER model is structurally incorrect or that you have introduced errors in the process of deriving relations from your model.
