What are the different types of keys in programming?
In programming, keys can refer to various concepts, such as primary keys in databases, encryption keys, and API keys. Each serves a unique purpose.
Why are primary keys important in databases?
Primary keys uniquely identify each record in a database table, ensuring data integrity and enabling efficient data retrieval.
Can you explain what an API key is?
An API key is a code passed in by computer programs calling an API to identify the calling program, its developer, or its user.
What happens if a primary key is duplicated?
If a primary key is duplicated, it violates the uniqueness constraint, leading to errors in data insertion and retrieval.
Are there any best practices for managing keys?
Yes, best practices include using strong, unique keys, regularly rotating keys, and securely storing them to prevent unauthorized access.
