PASS Healthcare February meeting

February 6, 2015 by neal Leave a Comment

Time to jump back into the Healthcare VC with our first meeting of 2015. This month’s speaker is by David Moutray. Please sign up at the PASS Healthcare website. The meeting is scheduled for Thursday, February 19, 2015 at 1 PM (Eastern).

Here are some details on David’s presentation.

Topic Name
Data Quality: Boosting Software Performance and Business Profit

Topic Synopsis
If “Data is the Lifeblood of Modern Business,” then most businesses are walking corpses with sludge in their veins, because 10% to 25% of all data records in the average enterprise are wrong. Until the dramatic problems of Data Quality Management are addressed, SQL can never fulfill its original promise to eliminate application “silos”, enable systems to communicate and provide useful, actionable information to the modern business. I believe that we are on the cusp of a revolution in Data Quality that is even greater in scope and impact than the revolution in manufacturing quality that began over 40 years ago. Businesses that make the transition will survive and thrive. Those that don’t will finally stop shambling about and lay down to die. What is this revolution in Data Quality? How can you be a part of it (and avoid the headman’s ax)?!? This presentation will change the way you think about your jobs as Database Administrators and Application Developers.

Speaker Bio
As a database administrator and ETL developer for a large data warehouse team, I am passionate about fast query performance, data integrity and the relational data model. Like most Database Administrators, I am highly opinionated, but unlike some, I am willing to endure personal abuse in the spirit of open discussion. I also tell (bad) jokes. Hecklers are welcome.

Hadoop training Day 2

February 5, 2015 by neal Leave a Comment

Day two of my training was all about Pig, which is a scripting language for exploring data sets.

Here is a list of a few topics we covered today:

  • Pig Latin
  • A few operators
  • Grunt
  • Bag
  • Joins

We also worked on a few examples covering clickstream and stock market data.

I’m starting to realize how much there really is to learn here. We’re cramming a lot of information into each session, but I think this is the best way to get some experience with it.

Hadoop training Day 1

February 4, 2015 by neal Leave a Comment

I decided it is finally time to jump in and start looking at Hadoop. I’d originally scheduled for Windows version of the class, but it was cancelled so I switched to the Apache version. At this point, I really wish I’d kept up with Linux commands…

Some of the topics we have discussed so far:

  • Overall Hadoop architecture
  • HDFS
  • YARN
  • MapReduce
  • Briefly discussed Pig, but will get into that more tomorrow

I’m taking the Hortonworks official training since they are a Microsoft partner. One thing that is a little odd is that I am the only one in my classroom. Everyone else (about 15) are in different cities/offices. I really set up with combination of cameras and WebEx. It seems to work well, at least so far. The learning facilitator is top notch as well. Definitely not his first time teaching the course.

Lots to learn with Hadoop and I am hoping this course will help me get up and running.
