This process of database schema design is also known as data modeling. 模式通常使用可视化表示来传达数据库的体系结构,成为组织数据管理规程的基础。数据库模式设计的这个过程也称为数据建模。 These data models serve a variety of roles, such as database users, database administrators, and programmers. ...
While conceptual, logical, and physical schemas contain different levels of information about databases in their diagrams, star and snowflake schemas represent those relationships between entities differently. More specifically, a star schema is a type of relational database schema that is composed of a...
