Decline of the ODS

"Remember the great proliferation of data marts in the late 1990s? By the turn of the century, most large corporations had dozens — sometimes hundreds — of data marts, resulting in an administrative nightmare. Then the pendulum swung the other way, and the same companies consolidated their data marts as best they could, during the great database consolidation that geared up in 2001. According to Giga Information Group, 17 percent of Global 2000 companies completed a data mart consolidation project by the end of 2002"

writes Philip Russom for Intelligent Enterprise.

"Most IT professionals are fully aware of the rise and fall of the data mart, yet few realize (or will admit) that the operational data store (ODS) is suffering an analogous and equally painful trend."
