A primary key is a field that contains data unique to a record, allowing for the identification and retrieval of individual records. It serves as the basis for establishing relationships between tables in a database. A query is a request for specific information from a database, a parameter is a value used in a query to filter or sort results, and a key-value is a method of organizing and storing data in which each value is associated with a unique key.
