This book offers a comprehensive introduction to relational (SQL) and
non-relational (NoSQL) databases. The authors thoroughly review the
current state of database tools and techniques, and examine coming
innovations.
The book opens with a broad look at data management, including an
overview of information systems and databases, and an explanation of
contemporary database types:
- SQL and NoSQL databases, and their respective management systems
- The nature and uses of Big Data
- A high-level view of the organization of data management
Data Modeling and Consistency
Chapter-length treatment is afforded Data Modeling in both relational
and graph databases, including enterprise-wide data architecture, and
formulas for database design. Coverage of languages extends from an
overview of operators, to SQL and and QBE (Query by Example), to
integrity constraints and more.
A full chapter probes the challenges of Ensuring Data Consistency,
covering:
- Multi-User Operation
- Troubleshooting
- Consistency in Massive Distributed Data
- Comparison of the ACID and BASE consistency models, and more
System Architecture also gets from its own chapter, which explores
Processing of Homogeneous and Heterogeneous Data; Storage and Access
Structures; Multi-dimensional Data Structures and Parallel Processing
with MapReduce, among other topics.
Post-Relational and NoSQL Databases
The chapter on post-relational databases discusses the limits of SQL -
and what lies beyond, including Multi-Dimensional Databases, Knowledge
Bases and and Fuzzy Databases.
A final chapter covers NoSQL Databases, along with
- Development of Non-Relational Technologies,
- Key-Value, Column-Family and Document Stores
- XML Databases and Graphic Databases, and more
The book includes more than 100 tables, examples and illustrations, and
each chapter offers a list of resources for further reading.
SQL & NoSQL Databases conveys the strengths and weaknesses of
relational and non-relational approaches, and shows how to undertake
development for big data applications. The book benefits readers
including students and practitioners working across the broad field of
applied information technology.
This textbook has been recommended and developed for university courses
in Germany, Austria and Switzerland.
