Abstract: Business Intelligence (BI) has evolved from static reporting to interactive, self-service analytics, enabling organizations to make data-driven decisions in real time. Qlik Sense, a leading BI platform, offers an associative in-memory data model, advanced visualization tools, and robust ETL capabilities that empower users to explore and analyze complex datasets efficiently. This review article focuses on advanced data modeling techniques and performance optimization strategies that enhance Qlik Sense dashboard responsiveness, scalability, and usability. Key topics include star, snowflake, and galaxy schemas, management of synthetic keys and circular references, incremental loading, and QVD optimization. The article also highlights best practices in dashboard design, scripting, set analysis, and integration with external analytics tools like R and Python, enabling predictive and prescriptive analytics. Practical applications across finance, healthcare, retail, and supply chain sectors demonstrate how Qlik Sense supports actionable insights, operational efficiency, and strategic decision-making. Additionally, the review addresses common implementation challenges, such as data quality issues, model complexity, and user adoption barriers, and proposes mitigation strategies through governance, training, and iterative refinement. Future trends, including AI-driven analytics, cloud deployment, mobile BI, and natural language querying, illustrate the ongoing evolution of Qlik Sense as an intelligent, user-centric BI platform. By adopting advanced modeling techniques, optimization strategies, and best practices, organizations can fully leverage their data assets to drive informed, timely, and sustainable business decisions.
