Does oracle 10g provide any special time series data features? I have a developer who "thinks it used to be an option in 8i". Is this OLAP, and is this included as a standard feature in 10g, or is it an add-on?
If special time series data features have something to do with Oracle Data Warehousing, then ... well, I guess this is the answer. You might check the Data Warehousing and Business Intelligence section of the Oracle Documentation.
