Explain the Role of Primary Keys in SQL Database Design.
Article Introduction：The primary key is a field or field combination in a database table that uniquely identifies each row of data. Its core function is to ensure data integrity, improve query efficiency and support foreign key constraints. The primary key must satisfy uniqueness and non-emptyness. Each table can only have one primary key, but it can consist of multiple columns to form a composite primary key. It maintains data consistency by preventing duplicate records and providing a basis for foreign key references, while automatically creating indexes to speed up queries. When selecting primary keys, the principles of stability, simplicity and business-free meaning should be followed. Common methods include self-incremental integers, GUID/UUID and natural keys if necessary. Composite primary keys are suitable for situations where a single field cannot uniquely identify data. For example, student ID and course ID form the primary key of the course selection schedule, but due to its complexity and performance impacts.

Many online services support offline access, such as Gmail, Google Docs, and Google Calendar. Of course, you can't download new emails or sync new files, but you can view what you saved when you last connected to the network.
It should be noted that you may not be able to enable offline access while the network is off-network, so be sure to plan in advance and check when there is a network connection.
