The normal term would be a primary key, not a record key.
A primary key is a unique identifier for a record in a database table and is used to ensure each record is uniquely identifiable. A secondary key is a key used for sorting and indexing purposes, but can have duplicate values within a table.
The primary key is the field containing unique values that aid in database operations. The secondary key is used in addition or as an alternate to the primary key. Both are candidate keys, it's just that one was chosen to be primary.
ID number
Primary key uniquely identifies each record in a database table and must have a unique value for each record. Secondary key is a field that can be used to uniquely identify a record, but it is not the primary key. Foreign key is a field in a table that links to the primary key of another table, establishing a relationship between the two tables.
Attribute is the property of entity.The composite attribute is like address(where street no,house no,town name all include).Composite key is also an attribute,but only which attribute are work as a unique identifier. Example:> In an ERD if vendor placed with orders then order(order day, order number) vendor(vendor code,vendor address) Here, order and vendor both are entity and order number, vendor code both are Composite key(because those are unique)but vendor address is a Composite attribute and order day(may be not unique)is an attribute only. So, we can conclude that all attribute not Composite key.
That is true :)

The best method for identifying patients using two patient identifiers is to implement a dual-identifier system that combines at least one unique identifier, such as a medical record number or national ID, with a secondary identifier, like date of birth or phone number. This approach enhances accuracy and minimizes the risk of misidentification. Utilizing technology, such as biometric systems or secure databases, can further streamline the process and ensure patient safety and privacy. Regular audits and training for staff also play a crucial role in maintaining effective patient identification protocols.
