Synopsis
● An important step in database implementation is the data modeling, because it facilitates the understanding of the project through key features that can prevent programming and operation errors.
● In database technologies, some of thenew issues increasingly debated arenon-conventional applications, includingNoSQL (Not only SQL) databases, whichwere initially created in response tothe needs for better scalability, lowerlatency and higher flexibility in an eraof bigdata and cloud computing. Thesenon-functional aspects are the main reasonfor using NoSQL database.
● Data modeling has an important role to play in NoSQL environments. The datamodeling process involves the creation of a diagram that represents the meaning of the data and the relationship between the data elements. Thus, understanding is a fundamental aspect of data modeling and a pattern for this kind of representation has few contributions for NoSQL databases.
● This book explains a NoSQLdata modeling standard, introducing modeling techniques that can be used on document-oriented databases. We have considered Cassandra and Riak NoSQL databases because of the heterogeneous characteristics of each NoSQL database classification.
