Installing Scala and Apache Spark on a Mac

The following outlines the steps I've followed to get get Scala and Apache Spark installed on my Mac. This allows me to play with Apache Spark on my laptop (single node) before deploying my code to a multi-node cluster.

The reason why I want to highlight this is because Christian … Continue reading "Going to the core of Oracle Analytics"

Getting Smarter in Renting with Tableau 10

Preface

Not a long time ago a friend of mine spent a significant amount of time trying to find a flat to rent. And according to what he said it wasn't an easy task. It took him a decent time and efforts to find something that is big enough (but not too big) not too far from a workplace, had required features and affordable at the same time. And as a specialist in data analysis, (more...)

Importance of BI tools for Pharmaceutical Industry

The pharmaceutical industry has been focusing much of its energy on producing the next chartbusting drugs.

However, the industry is also facing challenges in terms of the changing regulations, increasing number of declines on drug approvals and the continuing need to develop high value biologics. Refocusing efforts is imperative.

There are existing processes, systems and practices that need to be immediately addressed. Key performance indicators (KPI) using BI tools help corporations identify areas that need (more...)

Unify – An Insight Into the Product

Unify - An Insight Into the Product

Monday, 12 Jun saw the official release of Unify, Rittman Mead's very own connector between Tableau and OBIEE. It provides a simple but powerful integration between the two applications that allows you to execute queries through OBIEE and manipulate and render the datasets using Tableau.

Unify - An Insight Into the Product

Why We Made It

One of the first questions of course would be why we would want to do this in the first place. The excellent thing about OBI (more...)

Unify: See Your Data From Every Perspective

Ad hoc access to accurate and secured data has always been the goal of business intelligence platforms. Yet, most fall short of balancing the needs of business users with the concerns of IT.

Rittman Mead has worked with hundreds of organizations representing all points on the spectrum between agility and governance. Today we're excited to announce our new product, Unify, which allows Tableau users to directly connect to OBIEE, providing the best of both (more...)

OAC: Essbase and DVCS

Finally managed to get around to having a proper look at Essbase within Oracle Analytics Cloud Service (OAC) after a busy couple of months. This post focusses mainly on initial impressions on the ‘out of the box’ the Essbase side of this - which we will explore in more detail in future posts, as well as more detail on the use of Essbase with DVCS.

Using Essbase with DVCS

One of the features we are (more...)

Business Intelligence for the Finance Industry

The banking and finance industry is experiencing continuous changes brought about by advances in technology. The changes are welcome – however not without the accompanying challenges.

As a result, the kind of market we now have is dynamic and Wall Street is making the necessary adjustments, not to dampen vibrancy in the market, but to improve strategies in line with the changing technology. That requires developing new tools and implementing them correctly.

Business Intelligence (BI) (more...)

Overview of the new Cloudera Data Science Workbench

Recently Cloudera released a new product called Cloudera Data Science Workbench(CDSW)

Being a Cloudera Partner, we at Rittman Mead are always excited when something new comes along.

The CDSW is positioned as a collaborative platform for data scientists/engineers and analysts, enabling larger teams to work in a self-service manner through a web browser. This browser application is effectively an IDE for R, Python and Scala - all your favorite toys!

The CDSW is deployed (more...)

First Steps with Oracle Analytics Cloud

Preface

Not a long ago Oracle added a new offer to their Cloud - an OBIEE in a Cloud with full access. Francesco Tisiot made an overview of it and now it's time to go a bit deeper and see how you can poke it with a sharp stick by yourself. In this blog, I'll show how to get your own OAC instance as fast and easy as possible.

Before you start

The very first (more...)

Benefits and Use of Analytics for Insurance

The world in which we live is a volatile world, a fact that doesn’t bode well for the insurance industry whose greatest ally is “certainty”. Analytics, however, can somehow fill the gap. In this regard, BI reporting tools such as data visualization software are extremely useful.

Advanced analytics for insurance allows all stakeholders in the industry to identify new growth opportunities and risk factors as soon as they take shape. Insurance companies such as yours (more...)

ACE Alumni

Today, I asked Oracle to move me from Oracle ACE Director status to Oracle ACE Alumni status.  There are a number of reasons why I decided to change status.  When I started answering questions on internet forums years ago, I did it to share what I had learned in order to help others.  The same goes for this blog which I originally started so that I could give better and more complete answers to questions (more...)

OBIEE upgrades and Windows vulnerabilities

OBIEE upgrades and Windows vulnerabilities

OBIEE upgrades and Windows vulnerabilities

These two topics may seem unrelated; however, the ransomware attacks over the last few days provide us with a reminder of what people can do with known vulnerabilities in an operating system.

Organisations consider upgrades a necessary evil; they cost money, take up time and often have little tangible benefit or return on investment (ROI). In the case of upgrades between major version of software, for example, moving from OBIEE 10g to 12c there are (more...)
