These non-functional aspects, which are very common in the treatment of spatial data, are the main reason for using NoSQL database. However, currently there are no systematic studies on the data modeling for NoSQL databases, especially the document-oriented ones. Therefore, this article proposes...
《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...
Documentmodels represent data as documents, with fields and values. They’re used in NoSQL databases, such as MongoDB and Couchbase. Time-seriesmodels are used to represent time-stamped data and are widely used in IoT and financial data analysis. ...

Graph Data Modeling for NoSQL and SQL Master a graph data modeling technique superior to traditional data modeling for both relational and NoSQL databases (graph, document, key-value, and column), leveraging cognitive psychology to improve big data designs. ...
(iv) graph databases [19,20]. For rationality, sanity and demonstrating the storage structure, the researchers follow the database schema techniques without losing the advantages of schema flexibility provided by NoSQL databases. Such schema modeling strategies in NoSQL databases are quite different ...

this approach isn't very scalable. Remember that, in NoSQL databases, there are nojoinsbetween containers, so joins aren't an option for you. Also remember that, for NoSQL databases, the objective is to reduce the number of requests by modeling data so that you can fetch your applic...
The data modeling principles for NoSQL databases rely on writes to the database being relatively cheap, and disk space is generally the cheapest resource. When designing your database, to get the most efficient reads, you might need to duplicate data. In Cassandra, you can create ...
