How to fill out normalisation so far lossless

How to fill out normalisation so far lossless:

1. Identify the key attributes: Determine the main attributes that uniquely identify each record in the database. These attributes will serve as the primary keys.
2. Eliminate redundant data: Look for repeated data or data that can be derived from other attributes. Remove or restructure this data to reduce redundancy and improve efficiency.
3. Separate data into tables: Divide the data into separate tables based on their functional dependencies and relationships. Each table should contain related information to ensure data integrity and reduce data duplication.
4. Define relationships between tables: Establish relationships between the tables using primary and foreign keys. This will enable data retrieval and manipulation across different tables, ensuring consistency and avoiding data inconsistencies.
5. Normalize the tables: Apply normalization rules to ensure data is organized and structured optimally. This includes removing partial dependencies and transitive dependencies, resulting in tables that are in a higher normal form.
6. Ensure lossless join: Verify that the resulting normalized tables can be joined back together without losing any information. This ensures data integrity is maintained throughout the normalization process.

Who needs normalisation so far lossless?

1. Database administrators: DBAs are responsible for designing and maintaining databases. They need normalisation techniques to ensure efficient storage, retrieval, and manipulation of data.
2. Software developers: Developers need to understand normalisation concepts to design robust and scalable database schemas that can handle complex business logic and relationships.
3. Data analysts and scientists: These professionals rely on well-structured and normalized data to perform accurate data analysis, reporting, and modeling.
4. Businesses and organizations: Normalisation benefits organizations by improving data quality, reducing redundancy, and increasing data integrity. This ultimately leads to more efficient operations and better decision-making.
