Oracle Application Express - Background

Background

Historically speaking, Application Express has gone through many name changes since its inception in 2000. A reasonably complete history of the names includes:

  • Flows
  • Oracle Platform
  • Project Marvel
  • HTML DB
  • Application Express (APEX)

One popular misconception is that Application Express is merely new version of Web DB. Mike Hichwa created Web DB, a successful web front-end for Oracle, but the development of Web DB started to move in a direction that diverged from Mike's vision. When tasked with building an internal web calendar, Mike enlisted the help of Joel Kallman and started "Flows". They co-developed the Web Calendar and Flows, adding features to Flows as they needed them to develop the calendar. In the earliest days of Flows, there was no front-end for it, so all changes to an application were made in SQL*Plus via inserts, updates and deletes. In some ways APEX is an evolution of Web DB, but it was developed with new code and no upgrade path.

A popular application developed in Application Express is the AskTom application developed by Thomas Kyte. Oracle's Metalink support site had been running on APEX, but was replaced with a Flash version in September 2008. Oracle's online store also runs on APEX.

Famous quotes containing the word background:

    ... every experience in life enriches one’s background and should teach valuable lessons.
    Mary Barnett Gilson (1877–?)

    I had many problems in my conduct of the office being contrasted with President Kennedy’s conduct in the office, with my manner of dealing with things and his manner, with my accent and his accent, with my background and his background. He was a great public hero, and anything I did that someone didn’t approve of, they would always feel that President Kennedy wouldn’t have done that.
    Lyndon Baines Johnson (1908–1973)

    Pilate with his question “What is truth?” is gladly trotted out these days as an advocate of Christ, so as to arouse the suspicion that everything known and knowable is an illusion and to erect the cross upon that gruesome background of the impossibility of knowledge.
    Friedrich Nietzsche (1844–1900)
