The process of developing a database implementation (schema) from a data model is termed physical database design. In short, the data model defines what data must be represented in the application and the database schema defines how that data is stored. The goal of data modeling, also ...
Improved data models for databases may be achieved by improving the quality of synthetic data upon for modeling those databases. According to some aspects, these and other benefits may be achieved by using numeric distribution information in a schema describing one or more numeric fields and, based...
