Which of the following below is the best description of a stored procedure?

Stored procedures are widely used in many database management systems to contain SQL statements. The database administrator (DBA), or someone designated by the DBA, creates the various SQL statements that are needed in that business, and then programmers can simply call the stored procedures. Stored procedures are not related to dynamic linked libraries (DLLs). Stored procedures could be called by other stored procedures that are also on the server. Finally, stored procedures are not related to middleware.
