First look at QlikView Direct Discovery

Direct Discovery is one of the recent and long awaited features of QlikView which became available starting from version 11.2. Direct Discovery allows mixing data from external data sources and from QlikView's in-memory data engine using the same QlikView scripting language and expressions. Aim of Direct Discovery is to go beyond RAM limitations and enable real-time querying against large volumes of data outside of QlikView, while presenting the same associative experience as for regular in-memory data. Here are two good documents that describe it in more details: QlikView Direct Discovery Datasheet and QlikView Direct Discovery FAQ.

From development standpoint, Direct Discovery can be employed by two ways: using DIRECT SELECT statement in loading script and SQL( ) function in expressions.
