How can I prevent data duplication in my database?
To prevent data duplication, you can implement unique constraints on your database fields, use data validation, and regularly clean your data.
What are unique constraints and how do they work?
Unique constraints ensure that all values in a column are different from each other, preventing duplicate entries.
Can you suggest some data validation techniques?
Sure! You can use input validation, regular expressions, and data type checks to ensure data integrity and prevent duplicates.
How often should I clean my data to avoid duplication?
It's best to clean your data regularly, such as monthly or quarterly, depending on how frequently your data changes.
