1. What are the differences between an SQL agent and an SQL implementation An SQL agent is any structure that causes SQL statements to be executed. The SQL agent is bound to the SQL client within the SQL implementation. An SQL implementation is a processor that executes SQL statements according to the requirements of the SQL agent. The SQL implementation includes one SQL client and one or more SQL servers. The SQL client establishes SQL connections with the SQL servers and maintains data related to interactions with the SQL agent and the SQL servers. An SQL server manages the SQL session that takes place over the SQL connection and executes SQL statements received from the SQL client.
