| OData
OData is a Web API for Data Access and manipulation. It is similar to a
mini-ODBC or JDBC API but specifically intended for the Web. More precisely, OData allows clients to construct URIs that name an entity set, filter among the entities it contains, and traverse relationships to related entities and collections of entities. OData provides mechanisms for resources (also known as providers) to present descriptions of the data structures they expose and for clients (also known as consumers) to access and manipulate the exposed portions of the resources via the HTTP protocol. The OData Web API describes how requests from clients and results from the providers should be formatted. The OData specification documents have been submitted to OASIS (Organization for the Advancement of Structured Information Standards) in May 2012.

| Optimize storage with deep compression in DB2 10
Organizations are generating more data now than at any other time in history. And the need to comply with legal and governmental
regulations means that they're keeping that data around for longer periods of time. As a result, databases are growing at an astonishing
rate. In fact, according to industry analysts, enterprise databases are growing at the rate of 125 percent annually. This explosion in
data volume places tremendous pressure on enterprises to store, protect, distribute, and derive value from all the data being generated.
In 2007, IBM responded to this pressure by introducing new compression technology, known as Deep Compression, in DB2 Version 9. Since then,
IBM has improved this technology in subsequent releases of DB2. This article describes the various compression methods that are available
in DB2 Version 10.1, as well as provides recommended "best practices" that will help you achieve maximum storage space savings when you
adopt any of the compression techniques available.

| Develop software faster with continuous integration
Continuous integration is a software development practice in which members of a team integrate their work frequently; usually each person integrates at least daily which leads to multiple integrations per day. Each integration is verified by an automated build (including test) to detect integration errors as quickly as possible. Many teams find that this approach significantly reduces integration problems and allows a team to develop cohesive software more rapidly. Therefore, continuous integration, especially in the early stage of development process, can greatly improve the efficiency and help find potential issues as soon as possible. The authors describe the practice of continuous integration using the IBM SmartCloud Enterprise as the framework.

permit any of these techniques, next-generation JVM languages do, with varying
implementation details. In this article, Neal Ford investigates how Groovy, Scala, and Clojure realize the intent of the Interpreter design pattern by allowing functional extensions in ways that Java does not.

| Comment lines: Using an adapter service pattern to build a more flexible, low maintenance ESB
Integrating multiple systems in a point to point manner can be very time
consuming and expensive to maintain. One common approach to resolve this issue
is to introduce an Enterprise Service Bus (ESB), which replaces the point to
point approach with a single, centralized place to integrate systems, and does
so in a service-oriented manner. However, if done incorrectly, this can still
create maintenance headaches. Here is a look at a pattern that can “future
proof” your integration work, allowing for the upgrading or replacement of legacy systems without excessive additional integration work.

| XML data mining, Part 1: Survey several approaches to XML data mining
XML is used for data representation, storage, and exchange in many
different arenas. This series explores one facet of XML data analysis: XML data mining. In
this first article, get an introduction to some techniques and approaches for mining hidden knowledge
from XML documents. Learn about mining data, the hierarchical structure of
the information, and the relationships between elements. Subsequent articles will cover
mining XML association rules and clustering multi-version XML documents.

rules from XML documents. Mining association rules from XML documents is different from mining rules
from relational data. Information can be structured differently in XML because of the
language's flexibility and hierarchical organization. This article also introduces the notion of dynamic association
rules. You'll explore an approach to mining XML association rules when the underlying XML
documents change without a full re-run of the association rules discovery algorithm.

| DB2 best practices: Multi-temperature data management
Data in a data warehouse can be classified according to its temperature. The temperature
of data is based on how often it is accessed, how volatile it is, and how important the
performance of the queries that access the data is. Hot data is frequently accessed and
updated, and users expect optimal performance when accessing this data. Cold data is
rarely accessed and updated, and the performance of the queries that access this data is
not essential. Using faster, more expensive storage devices for hot data and slower, less
expensive storage devices for cold data optimizes the performance of the queries that
matter most while helping to reduce overall cost.

| Make your HTML pages smarter with RDFa 1.1 Lite
Resource Description Framework (RDF) has evolved into increasingly
pragmatic formats over time. RDF annotation (RDFa) has been particularly
successful as a system for annotating HTML documents inline on the web. It is
supported by Google and other search engines in the form of Rich Snippets. The
emergence of microdata and the Schema.org initiative applied pressure to
simplify RDFa even further. The W3C took action and produced a radically
simplified version: RDFa 1.1 Lite. In this article, learn about RDFa Lite, and
get a head start on producing and processing the shape of Rich Snippets to come.

| Meet six misunderstood Ruby features
Suppose you are a C++ developer and you
need to do some prototyping quickly in Ruby. When you pick up a Ruby reference book
like the Pickaxe or browse the Ruby site, you see familiar constructs like
class declaration, support for threads, and exception handling. Just when
you thought you knew how Ruby works, you realize that concurrency in your Ruby code is
not behaving like Boost threads, catch and throw are not what they seem, and others have used
something called self all over the place in their Ruby script. Welcome to Ruby!
