Database normalization techniques and best practices

Jacob0 CommentsTECHNOLOGYData, Technology

Database normalization is the process of organizing data in a relational database to eliminate redundancy and dependency issues while ensuring data integrity and consistency. Normalization helps in achieving an efficient database design that minimizes data duplication and allows for easier data management and manipulation. Here are some normalization techniques and best practices: First Normal Form (1NF):Ensure that each table in the database has a primary key that uniquely identifies each row (record). Eliminate duplicate rows and ensure atomicity of data by storing only single values in each column. Avoid storing multiple values in a single column (e.g., comma-separated values). Second…
