Historic
This is the view that the book of Revelation is not a story of the end times, but an allegorical commentary representing the socio-political climate of the time. Generally, it is accept that Revelation was written when there was a lot of persecution of the early Christians, and oppressive imperial cult worship was imminent, implying that John of Patmos wrote the story in the form of vague symbols understood only to the readers to persuade them not to give into the persecution.
This view is taken by most liberal to moderate Biblical scholars, and it is explained a little more at
this site. The symbols identify Babylon as the Roman Empire, the seven headed dragon adorned in seven crowns as the seven preceding Roman kings, the woman in scarlet and purple as a symbol of Rome (because those are the colors of the Roman empire), the bizarre locusts that erupt out of the ground as Roman footsoldiers, and the Anti-Christ as Emperor Dolmitia.
Preterist
This view in general interprets Revelation as a story of the end-times, it states that all or most of the prophecies in Revelation and Daniel have been fulfilled. There are actually 2 kinds of preterism: Partial Preterism and Full Preterism:
Partial: this is generally the view that almost all of the prophecies have been fulfilled (by at least 70 AD because Jesus said he'd fulfill his prophecies before the end of the first generation) with the exclusion the Second Coming, Day of Judgment, and Rapture.
Full: believes that
all prophecies in scripture occurred before 70 AD. Generally, it takes the view that many of the prophecies in scripture dont tell of a Rapture, but rather the destruction of Jerusalem. It also takes the event known as the Second Resurrection, where the bible describes that the dead will raise physically out of the ground to be Judge by Christ, as more or less a symbolic event where souls resting in the Sheol rise spiritually to the Heavenly (or Hellish) realm.
In both types of preterism, the events in Revelation are told as occurring a very long time ago and are generally localized. It also views many of the apocalyptic events and depictions of the anti-christ as symbolic rather than of literal events or real people.
Futurist
Almost all people who believe in the Rapture are Futurists (or partial Futurists). The view that the prophecies in Revelation have yet to be fulfilled (a partial Futurists believes that we are already seeing the prophecies fulfilled today). The most notable difference between Futurism and Preterism is that Futurists believe that the events in Revelation are apocalyptic and will occur on a global scale.
Amillenialism
The belief that Jesus Christ's 1000 year reign in the Second Coming is figurative. Generally, this view is held by preterists who believe that Christ will not erect a physical church on Earth, but a spiritual church.
Premillenialism
This is the belief that after the Tribulation, Jesus Christ will establish a physical 1000 year reign on earth that will be paradise before the final judgment.
Postmillenialism
A view that ignores the Rapture and Tribulation, it states that the world will have a massive religious revival that will last for 1000 years (or an arbitrarily long length of time) of peace before Christ comes back for the final judgment.
Pretribulation
A view that says that believers will be raptured away before the Tribulation so they dont have to experience pain and suffering.
Midtribulation
A view that says the rapture will occur 3 1/2 years after the Tribulation has begun. Some take this view to imply that there will be several mini-tribulations, they even go so far as to say that massive alien abductions or planes that disappear from midair are "secular" explanations for the miniraptures.
Posttribulation
A view that states that believers are not spared the horrors of the Tribulation, but they will eventually be raptured at the end of the 7-year tribulation.
