The Qlik Sense SaaS catalog can now include data that is stored in relational databases such as Oracle, SQL Server and Snowflake increasing data reuse, visibility and governance while expanding the types of content that data engineers and stewards can manage and distribute. It also simplifies data use as data consumers no longer need to setup data connections as they can simply browse for the data they need within the catalog.
