《Data Modeling and Schema Design》这本书在详细介绍NoSQL的各种建模方法之前,先用了一个章节给我们讲解通用数据建模的基本知识。因此,即使作为程序开发者或DBA的你,已经陷入日常工作,忘却了数据建模的重要性,又或是过去没有系统性学习过数据建模,也可以从本书直接学习到完整的知识。 数据模型的概念名词: 一本好...
初看目录及导语,我认为《Data Modeling and Schema Design》(数据建模及模型设计)是每一位文档型数据库从业者必读的书,没有之一。 文档型数据库是NoSQL的一个总要分支,MongoDB以及我所在的巨杉数据库SequoiaDB都是JSON文档型数据库。本书讲解JSON的数据建模及模型设计,可谓是开山之作。 文档型数据库常常被贴上“...

They provide a schema for how the data will be physically stored within a database. As such, they’re the least abstract of all. They offer a finalized design that can be implemented as arelational database, including associative tables that illustrate the relationships among entities as well ...
Standard- Tables where you can store data and add to the navigation in model-driven apps. Most tables that you create will be standard. Several standard tables are created from the Common Data Model schema in a Dataverse environment.
schema的type,例如边label,属性key或顶点label,在第一次创建时(edge、properties、vertices)被分配给图的元素。每一个元素指定的type不能被改变,确保系统的type是稳定的。 这节之外的schema定义参数声明等,在Chapter 30, Advanced Schema讨论了schema tpye性能优化等。
Schemas commonly use visual representations to communicate the architecture of the database, becoming the foundation for an organization’s data management discipline. This process of database schema design is also known asdata modeling. These data models serve a variety of roles, such as database ...
Dimensional data modeling can result in a design called a star schema, which has denormalized tables, and it is used for building reporting and analytical systems. Dimensional models are designed to be great at getting data out of a data warehouse and into the hands of business users. By stor...
