Direct Discovery


Direct Discovery

The Direct Discovery capability in QlikView expands the potential use cases for Business Discovery, enabling business users to conduct associative analysis on larger data sources. It provides the complete associative experience of QlikView on top of data coming directly from larger external data sources and enables users to combine that big data with data stored in memory.

The Direct Discovery capability combines the associative capabilities of QlikView in-memory data set with a query model where not all of the source data is directly loaded into the QlikView data model. The aggregated query result is passed back to user interface so the Direct Discovery data set is part of the associative experience. You can navigate both on the in-memory data and the Direct Discovery data as a unified set.

You can create charts to analyze data from the combined data sets, make selections in either of the in-memory or Direct Discovery data, and see associations across them with the same characteristic QlikView colours; green, white, and grey.

In order to use Direct Discovery in QlikView, you must use special functions in the load script. The way you create charts from Direct Discovery fields differs somewhat from working with other data sources, and since all the data is not kept in-memory, there may be performance issues when large amounts of data are retrieved.
