Summary
This article explores the architectural approaches and technological challenges associated with developing data warehouses (DWH) tailored to the needs of small and medium-sized enterprises (SMEs) in Bulgaria. Based on empirical data from the National Statistical Institute (NSI) and Eurostat, the analysis reveals a significant digital transformation lag among Bulgarian enterprises. The study examines the evolution of data warehousing concepts, from the classical Kimball and Inmon methodologies to modern cloud-based solutions such as BigQuery, Snowflake, and AWS Redshift. Particular focus is placed on the specificities of the Bulgarian SME sector, identifying key barriers: shortage of qualified personnel (data analysts/engineers), limited financial resources, managerial psychological barriers, and regulatory requirements (GDPR). The research provides practical recommendations for Bulgarian entrepreneurs regarding the choice between on-premise and cloud solutions, emphasizing return on investment (ROI) and strategic steps for initiating business intelligence projects.
