Developing with Couchbase Server: Building Scalable, by MC Brown

By MC Brown

Ultra-modern hugely interactive web content pose a problem for standard SQL databases - the power to scale speedily and serve a great deal of concurrent clients. With this concise consultant, you are going to how to construct internet functions on most sensible of Couchbase Server 2.0, a NoSQL database that could deal with web content and social media the place millions of clients learn and write huge volumes of knowledge. utilizing meals recipe info as examples, this ebook demonstrates how one can reap the benefits of Couchbase's document-oriented database layout, and the way to shop and question facts with a variety of CRUD operations. detect why Couchbase is healthier than SQL databases with memcached stages for dealing with facts from the main interactive parts of your software.

The Data Model Resource Book, Vol. 2: A Library of Data Models by Industry Types

A brief and trustworthy solution to construct confirmed databases for center enterprise functionsIndustry specialists raved concerning the information version source ebook while it was once first released in March 1997 since it supplied an easy, reasonably-priced solution to layout databases for middle company features. Len Silverston has now revised and up to date the highly profitable First variation, whereas including a significant other quantity to maintain extra particular requisites of alternative companies.

Coloured Petri Nets: Basic Concepts, Analysis Methods and Practical Use

This ebook offers a coherent description of the theoretical and functional aspects
of colored Petri Nets (CP-nets or CPN). It exhibits how CP-nets were developed
- from being a promising theoretical version to being a full-fledged language
for the layout, specification, simulation, validation and implementation of
large software program platforms (and different structures within which people and/or computers
communicate by way of a few roughly formal rules). The book
contains the formal definition of CP-nets and the mathematical idea behind
their research tools. despite the fact that, it's been the purpose to jot down the publication in
such a manner that it additionally turns into appealing to readers who're extra in
applications than the underlying arithmetic. which means a wide a part of the
book is written in a mode that's towards an engineering textbook (or a users'
manual) than it really is to a standard textbook in theoretical desktop technology. The book
consists of 3 separate volumes.

The first quantity defines the internet version (i. e. , hierarchical CP-nets) and the
basic options (e. g. , the various behavioural homes akin to deadlocks, fairness
and domestic markings). It provides an in depth presentation of many smaIl examples
and a short evaluate of a few commercial purposes. It introduces the formal
analysis tools. FinaIly, it features a description of a suite of CPN tools
which help the sensible use of CP-nets. many of the fabric during this quantity is
application orientated. the aim of the quantity is to educate the reader how to
construct CPN versions and the way to examine those via simulation.

The moment quantity includes a unique presentation of the idea in the back of the
formal research equipment - particularly incidence graphs with equivalence
classes and place/transition invariants. It additionally describes how those research methods
are supported via computing device instruments. components of this quantity are particularly theoretical
while different elements are software orientated. the aim of the quantity is to teach
the reader find out how to use the formal research tools. this may no longer inevitably require
a deep realizing of the underlying mathematical concept (although such
knowledge will after all be a help).

The 3rd quantity incorporates a unique description of a range of industrial
applications. the aim is to record crucial principles and experiences
from the initiatives - in a manner that is necessary for readers who don't yet
have own event with the development and research of huge CPN diagrams.
Another objective is to illustrate the feasibility of utilizing CP-nets and the
CPN instruments for such initiatives.

Parallel Computational Fluid Dynamics 1995. Implementations and Results Using Parallel Computers

Parallel Computational Fluid Dynamics(CFD) is an the world over acknowledged fast-growing box. for the reason that 1989, the variety of members attending Parallel CFD meetings has doubled. so as to maintain tune of present worldwide advancements, the Parallel CFD convention each year brings scientists jointly to debate and document effects at the usage of parallel computing as a realistic computational device for fixing advanced fluid dynamic difficulties.

Hadoop: The Definitive Guide, 2nd Edition

Observe how Apache Hadoop can unharness the ability of your information. This complete source exhibits you the way to construct and preserve trustworthy, scalable, disbursed platforms with the Hadoop framework - an open resource implementation of MapReduce, the set of rules on which Google equipped its empire. Programmers will locate info for studying datasets of any dimension, and directors will manage and run Hadoop clusters.

Sample text

With add() the operation will fail if the document ID you specify already exists. '); The add() function is useful when you are storing data into the database for the first time. For example, consider storing user data using the email address as the document ID. Using set() would overwrite an old user record. Using add() would fail the registration and indicate the user should use the password recovery system. The add() function is also atomic, so multiple writers can be adding data to the cluster at the same time, and it’s safe to use within a multi-threaded environment.

Each design document can contain mul‐ tiple views, and each view can contain both the map and optional reduce function. You can define multiple design documents per bucket.

Sometimes this is just for the purposes of external storage (for example on disk), but more complex solutions exist for object relational modeling (ORM), where an in‐ ternal object is translated into RDBMS based storage. With Couchbase Server an alternative model is available, with internal objects being serializable into the JSON format, which allows integration with the built-in document model, views and indexing. Within the PHP client library there are a number of optional connection options that configure how the client library behaves.
