Consultant Advises CMU Students on Cutting Edge Capstone Project

/in /by

Data Warehouse Consultants is focused on the Western Pennsylvania market and encourages our consultants to support the local institutions here.  Bob Brichacek,  a senior consultant for the firm, moonlights as an adjunct professor at the Carnegie Mellon University Heinz Graduate School.  Bob teaches a graduate course in Data Warehousing and acts as a regular sponsor of the Master’s of Information System Management’s “capstone” program.  This program is a semester-long project course where students work in teams to solve a real-world problem submitted by local businesses.

This year Bob’s team built an incredibly functional cloud-based video conversion tool using the Amazon Web Services cloud-based products.  This project has been featured on Carnegie Mellon’s website.  They write:

Bob Brichacek, the team’s faculty advisor, commended the students on their motivation and creativity, calling them “some of the smartest people I’ve ever worked with.”

“This is the most current technology. [The students] got to play with [tools] that a very small percentage of the population has played with,” said Brichacek. He adds that the pieces of the AWS toolset don’t just plug and play, and that the students’ main accomplishment was successfully customizing each piece to have the functionality Legendary required.

Excel External Content Blocked

/in /by
We have been encountering a new issue with Microsoft Excel and one of our clients had it today.  It took a little while to figure out, so we want to help out others in this situation.

 

Issue – Excel External/Web Content is Blocked: In most of our interactive applications, we allow for exporting data (either to csv or to xls extensions). By default, these downloads will open in Excel.  A recent update did something to Excel to prevent these files from opening.  It happened to my PC at home (just figured I did something). But then today, it happened at one of the client sites. Everything looks OK with the file when you download it, but either the file doesn’t open, or excel opens and there is no file there.  There is no error message or anything – the file just doesn’t open.

 

Resolution: When the file downloads, instead of opening the file, open the folder location to view the file. Right click the file, and click properties.  At the bottom of the window, there is an “Unblock” button. If you click unblock you can open the file. This shows that the file content is getting blocked because it came from the internet (external).  Unblocking it allows for opening the file (but you’d have to do that every time you download/open a file).  To not have to do it every time, you have to change excel settings.

 

Steps:
1. Open excel -> options -> trust center. Click “Trust Center Settings”.
2. Options -> Trust Center -> Click “Trust Center Settings”
3. Go to Protected View: Uncheck “Enable Protected View for files originating from the internet”.

 

After doing some research, it seems we are not the only ones experiencing this issue.  Here is a link to news article about it:

8/26/2016 Update – It seems like Microsoft has now resolved the issue.

UNIX Quick Start Guides

/in /by

Unix (all-caps UNIX for the trademark) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, developed in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
From the power user’s or programmer’s perspective, Unix systems are characterized by a modular design that is sometimes called the “Unix philosophy”, meaning that the operating system provides a set of simple tools that each perform a limited, well-defined function, with a unified filesystem as the main means of communication and a shell scripting and command language to combine the tools to perform complex workflows. Aside from the modular design, Unix also distinguishes itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language that allowed Unix to reach numerous platforms.

The .NET Framework (pronounced dot net) is a software framework developed by Microsoft that runs primarily on Microsoft Windows. It includes a large class library known as Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages. Programs written for .NET Framework execute in a software environment (as contrasted to hardware environment), known as Common Language Runtime (CLR), an application virtual machine that provides services such as security, memory management, and exception handling. FCL and CLR together constitute .NET Framework. Read more.

A top 10 Children’s Hospital Implements Radiology Tracking Board

/in /by

The radiology department of a top 10 Children’s Hospital began using a customized on-line patient tracking board created for them by Data Warehouse Consultants this week. This new application significantly reduces the phone calls and coordination that nurses, physicians and staff must do to efficiently move patients through the radiology department.

The implementation of the tracking board was the final result of an extensive development effort led by Data Warehouse Consultants. The firm worked with the hospitals staff to document the specific processes it uses to maintain a world-class facility.

These processes were then converted into a web-based application using Data Warehouse Consultants’ methodology to create a customized tracking board specifically for the radiology department. The tracking board allows staff in the department to monitor and update the status of X-ray, ultrasound, MRI and other radiology patients as they progress through the department.

Development in Sqoop 1 vs Sqoop 2

/0 Comments/in /by

I was working on a project last week to load data into a HDFS-based Hive database. This was essentially a periodic load so Sqoop appeared to be the best tool for the job. My small project consisted of the following goals:

– Connect Sqoop to SQL Server and/or Oracle instances
– Export a set of tables into HDFS files
– Load the data files into Hive tables

Sqoop was a new tool to me, so I started with the highest version which was 1.99.3. I was thinking that it’s almost always better to start with the new functionality in case you might need it. I struggled through the limited documentation but was eventually able to get Sqoop connected to both Oracle and SQL Server using the Command Line Interface available in Sqoop 2. The most challenging part of this exercise was working on the connection string and TCP/IP isues, but that’s a topic for another time.

I was able to export the tables into HDFS relatively easily, and I began looking for the run-time option that would allow me to automatically create the Hive table. I couldn’t figure out how to do it right away, but I was able to run a LOAD DATA operation in HIVE to load the data files into HIVE. This was an ok solution, but the problem is that I expected Sqoop to do this automatically. I needed to transfer about 500 tables, so loading them all manually was going to be a real pain.

After researching the issue further I discovered that the 1.99 version of Sqoop does not support the automatic creation of Hive tables that is available in 1.4.4 yet. Doh! This is a key requirement for my project with so many tables, so it turns out that choosing 1.99 was not the best decision. Once I knew that was the case, I began researching how to do this task in version 1.4.5 instead. In this version there is a simple –create-hive-table option that accomplishes my goal easily and seamlessly. Luckily for me most of the work I had already done on 1.99 translated fairly well back to 1.99. This allowed me to complete the project relatively quickly after I decided to roll back to an earlier version.

The moral of this story is that in the Wild Wild West of big data, newer is not always better. It pays to put the work in up front to be sure the version you are selecting meets you needs. In the open source world often the old version is older but “old reliable” – more reliable and has more features.

ACDHS Qualifies Data Warehouse Consultants to Build Custom Applications

Alleghany County Seal LogoPittsburgh, PA:  Allegheny County Department of Human Services (DHS) approved Data Warehouse Consultants to build business intelligence and web applications beginning in September 2014.
