数据库模型和数据模型之间有什么区别

what is the difference between the database model and the data model

推荐答案

想知道，谷歌不可用或者什么？ ：笑：



数据库模型是一种确定数据库逻辑结构的数据模型，从根本上决定数据的数据格式可以存储，组织和操纵。最流行的数据库模型示例是关系模型，它使用基于表格的格式。

数据模型组织数据元素并标准化数据元素的相关方式另一个。由于数据元素记录现实生活中的人，地点和事物以及它们之间的事件，因此数据模型代表现实，例如房屋有许多窗户或猫有两只眼睛。计算机用于计算这些现实生活中的事物和事件，因此数据模型是确保人与人之间精确交流的必要标准。

Wondering, google is not available or what ? :laugh:

A database model is a type of data model that determines the logical structure of a database and fundamentally determines in which manner data can be stored, organized, and manipulated. The most popular example of a database model is the relational model, which uses a table-based format.
A data model organizes data elements and standardizes how the data elements relate to one another. Since data elements document real life people, places and things and the events between them, the data model represents reality, for example a house has many windows or a cat has two eyes. Computers are used for the accounting of these real life things and events and therefore the data model is a necessary standard to ensure exact communication between human beings.
