What type of database does the Qlik Sense Repository Database run?

The Qlik Sense Repository Database operates as a relational database. This means it uses a structured format where data is organized into tables with predefined relationships between them. The relational model is instrumental in ensuring data integrity and enabling efficient querying through SQL (Structured Query Language).

Utilizing a relational database allows Qlik Sense to manage connections, user roles, and application metadata systematically, ensuring that various components of the Qlik environment can effectively interact with one another. This structured approach enhances the ability to manage relational data, which is critical for maintaining the consistency and reliability of the repository that supports the overall functionality of the Qlik Sense platform.

Other types of databases, such as analytical, NoSQL, or distributed databases, serve different use cases. While analytical databases focus on optimizing query performance over large datasets for analysis, NoSQL databases provide flexibility for unstructured data and scalability, and distributed databases manage data across multiple locations. However, the specific design and requirements of the Qlik Sense environment align more closely with the structured, relationship-based approach of a relational database.
