What does PK stand for in the context of Salesforce data management?

In the context of Salesforce data management, PK stands for Primary Key. A Primary Key is a unique identifier for a record in a database table. In Salesforce, every object has an identifier, which is typically a unique value that differentiates one record from another. This uniqueness is crucial for maintaining data integrity and ensuring that each record can be accessed and referenced independently without confusion.

Primary Keys are essential in database relationships, as they enable the establishment of links between different records across various objects. For example, in Salesforce, when you create a relationship between two objects such as Accounts and Contacts, the Account ID serves as a Primary Key that uniquely identifies each account within the system.

Understanding the role of the Primary Key is fundamental when designing data models and ensuring efficient data retrieval and storage strategies within Salesforce, as it lays the foundation for how records are connected and managed within the platform.
