Lexis Nexis: All content tagged as Lexis Nexis in NoSQL databases and polyglot persistence

MarkLogic, LexisNexis, XML, and Search

The lessons to be learned from the story about LexisNexis and MarkLogic—GigaOm and PR announcement—are quite simple:

  • Put XML into an XML database, objects into an Object Database, JSON into a document database, relational data into a relational database and you’ll get the best results
  • the better the data store understands the structure of your data, the better search results should be

Hortonworks Data Platform: Hortonworks’ Hadoop Distribution

Announcement came out today[1]:

Hortonworks Data Platform, powered by Apache Hadoop — As we began to interact with enterprises and ecosystem partners, the one constant was the need for a base distribution of Apache Hadoop that is 100% open source and that contains the essential components used with every Hadoop installation.  A distribution was needed to provide an easy to install, tightly integrated and well tested set of servers and tools. As we interacted with potential partners, we also heard the message loud and clear that they wanted open and secure APIs to easily integrate and extend Hadoop. We believe we have succeeded on both fronts. The Hortonworks Data Platform is such an open source distribution.  It is powered by Apache Hadoop and includes the essential Hadoop components, plus some that make it more manageable, open and extensible. Our distribution is based on Hadoop 0.20.205, the first Apache Hadoop release that supports security and HBase.  It also includes some new APIs, such as WebHDFS and those in Ambari and HCatalog, which will make it easy for our partners to integrate their products with Apache Hadoop. For those new to Ambari, it is an open source Apache project that will bring improved installation and management to Hadoop. HCatalog is a metadata management service for simplifying the sharing of data between Hadoop and other data systems. We are releasing Hortonworks Data Platform initially as a limited technology preview with plans to open it up to the public in early 2012.

The fight is on–even if for now the tone is still polite. And if we are adding to the mix MapR and LexisNexis’ HPCC, not to mention the armies of marketers and sales coming from Oracle, IBM, EMC, NetApp, etc. this actually smells like war.

Edward Ribeiro apty commented: “This reminds me of Linux distros war circa 2001”.

BI Pentaho Integrates Hadoop, NoSQL Databases, and Analytic Databases

Dr.Dobb’s:

  • The ability to orchestrate execution of Hadoop related tasks (i.e., executing a Hive Query, Pig Script, or M/R job) as part of a broader IT workflow.
  • The ability to setup dependencies, so if a step fails the job can branch down a recovery path or send a notification, or if it’s a success it goes on to subsequent dependent tasks. Likewise it supports initiating several tasks in parallel.
  • New integration for Pig — so that developers have the ability to execute a Pig job from a PDI Job flow, integrate the execution of Pig jobs in broader IT workflows through PDI Jobs, take advantage of our out of the box scheduler, and so on.

The list of tools Pentaho 4 integrates with is quite long:

  • a long list of traditional RDBMS
  • analytics databases (Greenplum, Vertica, Netezza, Teradata, etc.)
  • NoSQL databases (MongoDB, HBase, etc.)
  • Hadoop variants
  • LexisNexis HPCC

This is the world of polyglot persistence and hybrid data storage.
