Question

What are the steps involved in transforming a data model into a relational database design?

Answer 1

The steps involved in transforming a data model into a relational database design include analysis, mapping entities and relationships, defining attributes, establishing relationships, normalizing the design, and optimizing for performance.

Step-by-step explanation:

The steps involved in transforming a data model into a relational database design are as follows:

1. Analyze the problem and identify the information given.
2. Map the entities and relationships from the data model to tables in the database design.
3. Define the attributes and datatypes for each table.
4. Add primary and foreign keys to establish relationships between tables.
5. Normalize the database design to eliminate data redundancy.
6. Optimize the database design for performance and efficiency.

For example, let's say we have a data model representing a school. We would identify entities like students, teachers, and classes, and map them to tables in the database design. We would define attributes like student name, teacher name, and class name, along with their corresponding datatypes. We would establish relationships between tables using primary and foreign keys. And finally, we would normalize the design to eliminate any redundant data.
