DBMS Keys
DBMS Keys are an important part of any database. They are used to uniquely identify a row in a table. There are three types of keys in a DBMS: primary key, foreign key, and unique key. A primary key is a column or set of columns that uniquely identify a row in a table. A foreign key is a column or set of columns in one table that refers to the primary key in another table. A unique key is a column or set of columns that uniquely identify a row in a table, but does not reference any other table.A database management system (DBMS) is a collection of programs that enables you to store, modify, and extract information from a database. There are four main types of DBMS keys: primary keys, foreign keys, candidate keys, and composite keys.Primary Keys: A primary key is a unique identifier for each record in a table. Foreign Keys: A foreign key is a field in a table that matches the primary key of another table. Candidate Keys: A candidate key is a field in a table that could be used as a primary key. Composite Keys: A composite key is a combination of two or more fields in a table that uniquely identify a record.A key is a set of one or more database attributes (columns) used to uniquely identify a database row. A primary key is a key that uniquely identifies a row in a table. A foreign key is a key that uniquely identifies a row in another table. A composite key is a key that consists of two or more attributes (columns).A key is a single or combination of multiple fields in a table that uniquely identify a row in the table. Keys are used to create relationships between tables and to ensure data integrity. In a database, there are three types of keys: primary keys, foreign keys, and candidate keys. A primary key is a field in a table that uniquely identifies each row in the table. A foreign key is a field in one table that corresponds to the primary key of another table. A candidate key is a field or combination of fields that could be used as the primary key for the table.
