This is a follow-up to a previous question. Any time you provide the Salesforce interviewer with the answer, you should anticipate a follow-up question. This indicates that they either need more information or have a specific interest in this topic. If there are several follow-up questions about the same topic, they indicate that the subject is important to their operations. You should use it as a clue to talk more about the subject when answering their questions.

Anonymous Answer

A Network Protocol driver which uses an application server to convert JDBC calls directly or indirectly into the vendor-specific database protocol.
A Thin Driver which converts JDBC calls directly into the vendor-specific database protocol. This driver has the best performance, as it requires no client or server-side library, but it does depend on direct interaction with the Database.
