Transactional write priority: Its primary principle is to optimize for high-frequency insert and update transactional operations (OLTP).

Centralized simplicity: The design features one central table (facts) connected directly to descriptive tables (dimensions), forming a star shape. This simple structure makes it very easy for beginners to write reports and queries.

Zero redundancy: It enforces strict rules to ensure data is never repeated across tables, which saves the maximum amount of hard drive space but makes querying very slow and complicated.

Fast reporting: It is built for speed when reading data. By keeping connections simple, it allows business reports and charts to load quickly, even though it might use a bit more storage space.
