翻译下面短文。 A database management system (DBMS) or database software program enables the creation of a database—a collection of related data stored in a manner so that information can be retrieved as needed. In a relational DBMS (the most common type found on personal computers), a field or column is a collection of characters that make up a single piece of data, such as a name or phone number; a record or row is a collection of related fields; and a table is a collection of related records. One or more tables can be stored in a database file.
