NoSQL systems are characterized by high flexibility but also high heterogeneity.We argue that data modeling notions can be useful in the context on NoSQL databases.We propose NoAM, an abstract data model for No
《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...

They’re used in NoSQL databases, such as MongoDB and Couchbase. Time-series models are used to represent time-stamped data and are widely used in IoT and financial data analysis. Data Modeling Process Here are the 10 steps a data modeler or data architect typically takes during the ...
With NoSQL Workbench, you can: Define your data model using one or more tables. Visualize the data model to understand how it works in different scenarios. Build the data plane operations for multiple programming languages. In this blog post, I am using NoSQL Workbench, that is now ...
Promises of agility and schemaless data storage are always around the corner for NoSQL databases. And the thing is, it's all true: You can store unstructured data easily...but you'll need to apply structure when you actually use the data. Various solutio
SQL关系型数据库,需要多个Table描述数据关系,处理时还需要繁重的JOIN计算 JSON文档型数据库,可以简化表达,同时对最终用户更加直观清晰 JSON文档型数据库,采用子对象和数组嵌套的“逆规范化(Denormalize )”数据模式来表示关系,确实会增加存储消耗(包括网络传输方面的消耗)。但考虑到如今存储成本、计算、网络传输带宽成本...
Data modeling is the process of creating a diagram that represents your data system & defines the structure, attributes, and relationships of your entities.
