MarkLogic 6: An introduction

By

The latest permeation of MarkLogic (version 6) offers ACID (atomicity, consistency, isolation, durability) transactions, horizontal scaling, real-time indexing, high availability, disaster recovery, government-grade security and built-in search.

MarkLogic has made application development easier with Java and REST APIs. They also added JSON support. This allows developers to use their language of choice, and eliminate the need to learn new production language. It also provides data visualization widgets. These widgets can display the shape and dimensions of data, identify trends or patterns and explore the data as a whole.

Version 6 also comes with built in database analytics. Integration with IBM Cognos and Tableau is included as well. This enables analysts to create reports, dashboards and the data. Lastly, version 6 adds the in-database MapReduce capabilities.

Find out more about MarkLogic version 6 here.

And here is more from their website:

Mission-critical Big Data Applications around the world are powered by MarkLogic. It is the only Enterprise NoSQL database that manages all types of data at scale in real time. It gives you the range of features you need to deliver value. It lets you leverage your existing tools, knowledge, and experience. And it provides a reliable, scalable, and secure platform for your important data.

New Feature Highlights

Business Intelligence Tools

Business Intelligence Tools
Big Data in the enterprise needs to be accessible to everyone who could benefit from the information. To make that easier, MarkLogic now includes out-of-the-box integration with Business Intelligence tools like IBM Cognos and Tableau to allow analysts to use familiar solutions for generating reports, dashboards and data exploration results from data stored in MarkLogic.

 

REST API

REST API
In order to enable developers to work in their language of choice, MarkLogic now includes a REST API that allows you to perform searches, create documents, read documents, update documents, and delete documents. The REST API allows you to build fully functional MarkLogic applications in any programming language. It also allows you to directly load JSON documents.

 

MarkLogic Java API

MarkLogic Java API
The new Java API allows you full-featured access to MarkLogic functionality with pure Java. The MarkLogic Java API is written on top of the REST API, and has all of its functionality such as paginated search with facets and snippets, full document CRUD operations, and more.

 

Enhanced JSON Support

Enhanced JSON Support
Our new JSON library makes it easy to store JSON documents as key-value stores, and to convert them back and forth between JSON and XML. The REST Client API and the MarkLogic Client API for Java make use of this functionality to make it easier to load and work with JSON documents.

 

Visualization Widgets

Visualization Widgets
We’ve also added Visualization Widgets so you can easily build powerful applications that help your users discover the shape and dimensions of data, quickly assess trends and patterns, and explore data more intuitively. You can access these widgets with MarkLogic Application Builder.

 

In-database MapReduce & User Defined Functions

In-database MapReduce & User Defined Functions
Many customers wanted more flexibility to develop complex, real-time analytics. We’ve extended MarkLogic 6 to let you create user-defined aggregate functions (UDFs) that take advantage of MarkLogic’s parallel-processing architecture. We call this In-database MapReduce, and it lets you create blindingly fast analytic functions with custom C++ code by writing “map” and “reduce” functions.

 

In-Database Analytic Functions

In-Database Analytic Functions
In order to enable customers to leverage the power of the MarkLogic platform to produce enterprise-grade analytics, we’ve included several built-in XQuery functions to perform analytic and statistical functions.

 

MarkLogic Content Pump (mlcp)

MarkLogic Content Pump
In order to speed loading and exporting of data between databases, we are introducing the MarkLogic Content Pump (mlcp). mlcp is a command-line tool for loading content into MarkLogic Server and for migrating content from one instance of MarkLogic to another, even if they are on different platforms. If you have a Hadoop cluster, mlcp takes advantage of Hadoop to parallelize the loading. mlcp takes much of the functionality of the open source projects Record Loader and xqsync and bundles them in a single package, and allows them to take advantage of Hadoop if it is available; Hadoop is not required to use mlcp, but is used if it is available.

 

FIPS 140-2 Cryptographic Compliance

FIPS 140-2 Cryptographic Compliance
MarkLogic 6 includes the OpenSSL Federal Information Processing Standard (FIPS) Object Module, which was evaluated by the National Institute of Standards (NIST) for FIPS 140-2 compliance. More details on the OpenSSL Object Module and on the FIPS 140-2 compliance.

 

Search API Enhancements

Search API Enhancements
When you’ve got a lot of data, great search is key. We’ve worked to make our search API even better with the following enhancements:

  • Structured Search
  • Extracting metadata at search time
  • Modify the unconstrained term behavior using <search:term>
  • Range constraints for path range indexes
  • Ability to return values from range indexes with search:values
  • JSON key support

 

Path Range Indexes

Path Range Indexes
In order to enable fine-grained range indexes while maintaining the advantages of using the lexicon functions and the range query constructors MarkLogic now includes support for range index specified by a path. You can specify a subset of XPath as the definition of what goes into an index. The search API can take advantage of path range indexes to create range constraints on them. Path range indexes are also useful when setting up SQL views on data stored in a MarkLogic database.

 

Synonym Search

Synonym Search
You now have the option to ensure that documents that contain multiple synonyms are scored appropriately, rather than unnaturally gaining points to the search score. Learn more about how the architecture of MarkLogic works and how you can deploy it.

There is no time to wait for long development cycles that produce software that is obsolete at launch. DevOps may be disruptive, but it is essential.
Explosive growth in connected devices. Enormous amounts of data for collection and analysis. Critical use of data for split-second decision making and actionable information. All three are factors in making the Internet of Things a reality. Yet, any one factor would have an IT organization pondering its infrastructure strategy. How should your organization enhance its IT framework to enable an Internet of Things implementation? In his session at Internet of @ThingsExpo, James Kirkland, Chief Architect for the Internet of Things and Intelligent Systems at Red Hat, described how to revolutioniz...
Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.
The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example t...

The Internet of Things (IoT) is the biggest idea since the creation of the Worldwide Web more than 20 years ago.
The definition of IoT is not new, in fact it’s been around for over a decade. What has changed is the public's awareness that the technology we use on a daily basis has caught up on the vision of an always on, always connected world. If you look into the details of what comprises the IoT, you’ll see that it includes everything from cloud computing, Big Data analytics, “Things,” Web communication, applications, network, storage, etc. It is essentially including everything connected online from hardware to software, or as we like to say, it’s an Internet of many different things. The difference ...
How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happens, where data lives and where the interface lies. For instance, it's a mix of architectural styles ...
The security devil is always in the details of the attack: the ones you've endured, the ones you prepare yourself to fend off, and the ones that, you fear, will catch you completely unaware and defenseless. The Internet of Things (IoT) is nothing if not an endless proliferation of details. It's the vision of a world in which continuous Internet connectivity and addressability is embedded into a growing range of human artifacts, into the natural world, and even into our smartphones, appliances, and physical persons. In the IoT vision, every new "thing" - sensor, actuator, data source, data con...

"Matrix is an ambitious open standard and implementation that's set up to break down the fragmentation problems that exist in IP messaging and VoIP communication," explained John Woolf, Technical Evangelist at Matrix, in this SYS-CON.tv interview at @ThingsExpo, held Nov 4–6, 2014, at the Santa Clara Convention Center in Santa Clara, CA.
We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...
The 3rd International @ThingsExpo, co-located with the 16th International Cloud Expo - to be held June 9-11, 2015, at the Javits Center in New York City, NY - announces that it is now accepting Keynote Proposals. The Internet of Things (IoT) is the most profound change in personal and enterprise IT since the creation of the Worldwide Web more than 20 years ago. All major researchers estimate there will be tens of billions devices - computers, smartphones, tablets, and sensors - connected to the Internet by 2020. This number will continue to grow at a rapid pace for the next several decades.
The Internet of Things will greatly expand the opportunities for data collection and new business models driven off of that data. In her session at @ThingsExpo, Esmeralda Swartz, CMO of MetraTech, discussed how for this to be effective you not only need to have infrastructure and operational models capable of utilizing this new phenomenon, but increasingly service providers will need to convince a skeptical public to participate. Get ready to show them the money!
