• Why use Hadoop?
• What is Hadoop?
• Recognizing Use Cases
• Some Use Cases

Apache Hadoop has evolved into the standard platform solution for data storage and analysis.

Two key aspects of Hadoop have driven its rapid adoption by companies hungry for improved insights into the data they collect:

• Hadoop can store data of any type and from any source—inexpensively and at very large scale.
• Hadoop enables the sophisticated analysis of even very large data sets, easily and quickly.

Internet Of Things Security Trends

Internet of things (IoT) is one of those buzzwords that has been around in recent years and is increasingly gaining popularity as it evolves into more concrete realizations. This article describes some of the most recent announcements.

Devoxx – Refactoring to Java 8 (by Trisha Gee)

A talk about refactoring to Java 8 and the impact on performance.

Why should you refactor to Java 8:

A simple, quick word on ARTIFICIAL INTELLIGENCE. What is Weak and Strong Artificial Intelligence?

What to do when max number of processes is exceeded in your Oracle database?

Metal Molly knew what they were saying, or they have been very popular in Ljubljana, but as the song goes, orange seems to be very smart!

This blog post describes how to build an xml file with Informatica Powercenter, considered as a rather complicated task. So this blog post explains the basics in this matter.

Some of the Devoxx 2015 talks really worth watching.

Now and then I get a request to create a graph in OBIEE that touches the boundaries as to what OBIEE is capable of. A quadrant like report, in which every quadrant has a different color was one of them. Naturally we succeeded.

Some tips on a performance issue I have faced multiple times: the tuning of a data warehouse query. Behold!

Below you can see an overview of a star schema (or a dimensional schema if you must) which is commonly used in business intelligence reporting tools.

Big data could really be called "big frustration", it hyped-up or even over-hyped?

The challenge of sifting through new and enormous sources of raw data from web activity logs, mobile click streams, machine sensors, and social media in Hadoop is daunting for organizations. Realizing strategic insight from Hadoop has been the domain of highly skilled and scarce data scientists, who use complex programming tools and a range of disjointed point solutions to find, explore, transform, analyze, and export the data the business needs. Blending the new unstructured data stored in Hadoop with NoSQL and relational databases provides a richer 360 degree view of customers and operations for competitive advantage.

Ever had that problem when, in reporting, some records just wouldn’t show because, basically, you were dealing with bad data? It happens more too often that data is loaded with empty id fields, simply because someone forgot to foresee an alternative or because of the all to known these-fields-will-never-be-empty assumption!

Just recently I was performing an OBIEE upgrade for a client on a windows machine. We were going from a 11.1.1.6.0 to a 11.1.1.7.1 OBIEE installation which is a pretty straightforward if you follow the right steps.

Are you tired of outdated confirmation boxes popping up every time you need to approve a delete action in one of your applications? I sure am. That’s why I decided to replace them with a jQuery dialog box. They are much more customizable to suit the look and feel of your application. The only requisite for this to work is to include the jQuery library in your application, which is integrated as of APEX 4.

One of the sessions at Oracle Open World 2014 was a session about the new features in the Oracle 12c database that can be of use for developers. The session was given by Alex Nuyten. (Most of the credits for this blog post go to him.)

Most recently, I was working on a project in which there was the requirement to populate multiple fields when selecting a value from an autocomplete list. This would make it possible for the end user to fill in an entire form with a single click of a button. Accomplishing this would highly enhance the user experience and reduce the repetitive steps of filling in a form.

A few notes on The Real World Performance Tour, organised by OBUG with Andrew Holdsworth, Tom Kyte and Graham Wood.

Most Java developers are familiar with Tomcat. It is a mature, lightweight and easy to use web server for Java web applications. But it still surprising how few people are aware and use some of the basic features/concepts of this application. This blogpost describes some of the features Tomcat users should be familiar with and use them as much as possible.

 Oracle released Endeca 3.1 with lot's of new features. Main focus of this release is Self-Service. 

This is our second article in a series featuring a hands-on experience with the Oracle Endeca Information Discovery 3.0 platform (short OEID). This post will be a brief summary of how to deploy the Getting Started application

Have you ever had the need to merge cells in OBIEE (11g), like you can do in Excel? Just to make a report look that much nicer? It’s possible!

How to integrate Google Charts/Maps in your OBIEE report in only a few minutes!

By upgrading your OBIEE 10g rpd file to OBIEE 11g by using the ua batch program (Upgrade Assistant), you can receive some connection pool errors by viewing at the data in the physical layer.

Oracle is a Leader in the recently published Gartner Magic Quadrants for Application Infrastructure (including SOA and SOA Governance).

When installing OBIEE 11g on a Windows machine some steps of the Configuration process may fail …
Or errors can show up when starting the domain.
