A data model is crucial for building business intelligence (BI) solutions that empower users to make data-driven decisions and identify new business opportunities. Data models are the pillars of a system and dat
physical storage structures (physical files). Data consistency is a hallmark of relational database models since they maintain data integrity across applications and database copies, also called instances. With a relational model database, multiple instances of a database always have the same data....
