Zahraniční

In the context of computer science (CS), „Zahraniční“ translates from Czech as „foreign,“ often used in the context of „foreign keys“ in database design. A foreign key is a field (or collection of fields) in one table that uniquely identifies a row of another table or the same table, creating a relationship between the two. This relationship enables established data integrity and referential actions, ensuring that relationships between tables remain consistent. The term can also refer to „foreign data,“ which can pertain to external databases, services, or resources that a given system interacts with. Understanding foreign keys and how they operate is critical for relational database management and ensures that data can be accurately related and retrieved within complex systems.
