I he need to handle increasingly larger data volumes is one factor driving
the adoption of a new class of nonrelational NoSQL databases. Advocates
of NoSOL databases claim they can be used to build systems that are
more
performant,
scale better, and are easier to program.
NoSOL Distilled is a concise but thorough introduction to this rapidly
emerging technology. PramodJ. Sadalageand Martin Fowler explain
how NoSQL databases work and the ways that they may
bea
superior
alternative to a traditional
RDBMS.
The authors provide a fast-paced guide
to the concepts you need to know in order to evaluate whether NoSOL
databases are right for your needs and, if so, which technologies you
should explore further.
The first part of the book concentrates on core concepts, including
schemaless data models, aggregates, new distribution models, the
CAP theorem, and map-reduce. In the second part, the authors explore
architectural and design issues associated with implementing NoSQL.
They also present realistic use cases that demonstrate NoSQL databases
at work and feature representative examples using Riak, MongoDB,
Cassandra, and Neo4j.
In addition, by drawingon Pramod Sadalage s pioneering work, NoSQL
Distilled shows how to implement evolutionary design with schema
migration: an essential technique for applying NoSQL databases. The book
concludes by describing how NoSQL is ushering in a new age of Polyglot
Persistence, where multiple data-storage worlds coexist, and architects
can choose the technology best optimized for each type of data access.
PRAMOD J. SADALAGE, Principal Consultant at ThoughtWorks, enjoys the
rare role of bridging the divide between database professionals and
application developers. He regularly consults with clients who have
particularly challenging data needs requiring new technologies and
techniques. He developed pioneering techniques that allowed relational
databases to be designed in an evolutionary manner based on
version-controlled schema migrations. With Scott Ambler, he coauthored
Refactoring Oataboses
(Addison-Wesley,
2006).
MARTIN
FOWLER, Chief
Scientist at ThoughtWorks, focuses on better ways to design software
systems and improve developer productivity. His books include Patterns
of Enterprise Application Architecture; UML Distilled, Third Edition;
Domain-Specific Languages (with Rebecca Parsons); and
Refactoríng:
Improving the Design of Existing Code [with Kent Beck, John Brant,
and William Opdyke)
