Open Suck… I mean Open Source

Posted by mysticstache on

If you’re reading this for a socialist country, I’m sorry but you’re going to struggle to understand the basic premise of this discussion. The application of a common cliché in capitalist societies, “You get what you pay for” I believe is universally appropriate. From my father-in-law, who bought the cheapest satellite service and complains incessantly about how much he wishes he had the same cable service I have but is unwilling to pay the higher service charges, to out sourcing call centers to regions of the world that speak a different language than the users of this service, to booking a cheaper hotel near the Orlando amusements with free shuttle service that’s just a glorified, overcrowded city bus without the graffiti. Going cheap is almost always going to disappoint. But this is a technical blog and my focus is Business Intelligence.

I’m working on a favor for a friend and I wanted to take this opportunity to explore some new technology. This friend of mine doesn’t have any budget for this project so I’m looking for cost effective components for this application that’s simply client front end to an RDBMS. My friend runs a small collection of Windows 7 desktops, I love Entity Framework, I’m proficient in Visual Studio, and I don’t need a “Big Data” solution. So I start thinking Open Source. Alright, hurdle 1, I’m not a java guy, and some of you might start harping about how Ruby, Rails, PHP running on Apache, Beans and Java all vastly different things…. I’m not into any of them; they’re all Java to me. A lifetime ago I played with swing and it sucked on Windows. Most Java apps I see run in Windows, are crap.

I don’t want to go into an in depth discussion on all the options, but I decided to investigate PostreSQL based on a recommendation from someone in my network who swears by it. One of the things I liked is the multi-OS support. Just in case the world turns upside down and I want to install the database one something other than a Microsoft OS, I thought I’d work with an RDBMS that would work the same no matter where it was installed with ne common client. The installation was smooth enough. I installed everything and clicked next, next, next… no errors. Good. Then I started researching ADO .NET clients to support Entity Framework, that’s where the wheels fell off.

In the realm of free providers to go with the free RDBMS; there is an OLEDB provider pgnpoledb, multiple JDBC drivers, and one ODBC/.NET provider npgsql. Now, I’m skeptical man and before I went down the path of actually trying to connect Entity Framework to the PostgreSQL database I decided to read the npgsql wiki. Pages were devoted to all the different issues and bugs, what was or wasn’t being submitted for acceptance in GitHub. From the headache mounting on my cranium, I could tell this option was going to require maybe a bit more effort than I was willing to invest in a favor for a friend. A lot of posters were pointing to the .NET provider for PostgreSQL from DevArt. Long story short, $199 for what I wanted… Wait a second I thought this crap was all Open Source and free!

Let’s just explore this concept, which has long been my complaint with the Open Source stack. If your goal is to create a mission critical high availability enterprise application with the Open Source offerings, you must be prepared to not only code your application, but also the platform on which it runs, or abandon the “Potentially Free” benefits of Open Source by purchasing licensed products to augment and stabilize the Open Source platforms. Option 1 means roughly doubling your workforce or your time to market. You need resources to code the platform and resources to code the application or resources that do both, but really only one at a time. Option 2 cuts into your equipment and tools budget and you need to verify what the vendor’s royalty and redistribution requirements are. No one wants to depend on a component that requires $1000 royalty for every user on a 40,000 seat client server application, right?

There are other Open Source challenges I love to joke with the diehard apologists I know. Like the fact that your favorite platform was written by one talented foreigner who doesn’t speak your language and only responds to email questions once a week when the internet service satellite flies over his bunker. I like a challenge as much as the next person, and I sympathize with the desire to revolt against the powerful software companies that are so slow to accommodate user needs. But, I’m just not willing to chance providing a service, where contractually I have to pay a refund for every minute of down time, dependent on a platform that was developed by hobbyists and amateurs.

Look at the example I stated above where the free provider has lots of challenges and the paid one is stable and supports all features of the toolset it’s meant to service. Developers whose livelihood (paycheck) is dependent on the successful execution of a project are naturally going to be more motivated to generate a better product than those who are working merely to support a community. Likewise, those tasks that facilitate the collection of said paycheck will take priority over the needs of a community, which leads you to have more down time as you wait for someone to get off from work (or high school marching band practice and homework) to fix a bug in the platform your product depends on and publish it to GitHub.

 

 

How are you coming with those TPS reports?

Posted by mysticstache on

Does anyone remember the original “Weekend at Bernie’s”? When the two accountants are pouring over the green and white dot matrix printouts of the accounts on the hot tar roof of their apartment building? That’s the traditional report, pages and pages of numbers. Until the invention of spreadsheets, this was the means by which accountants reviewed the accounts. Larger companies have since outgrown even spreadsheets and demanded larger data storage, like databases. However a majority of the reporting provided from these robust data stores still looks like a spreadsheet.

Detailed row data has its uses. Financial transactions and system audit logs are very useful when displayed as uniform rows of data for visual scanning. You can easily find the row that doesn’t look like the others when searching for an error, but how easy is it to determine transaction volume, or the frequency of a particular event? Are you going to count the lines and keep a tick mark tally on another sheet? You can calculate some of these statistics and group them by date, and compare the groups if all the data is still available at the source. Hopefully the query doesn’t slow down the system while users are trying to do their work on it. Save the data in monthly spreadsheets that are backed up regularly? In most cases, the generation of these reports just becomes a meaningless process and waste of paper.

Business Intelligence (BI), I don’t know who coined the term, is meant to communicate the difference between a report (any formatted delivery of data) and the display of information in a way that aides in the business decision making process. BI reporting answers questions like how are this month’s sales compared to last month’s? Or has there been a statistically significant increase in defects with the new modifications to our product?

Many professionals familiar with BI reporting make the assumption that it’s really only applicable to data collected and aggregated over a large period of time. Contact center management is the best example of why this isn’t the case. A contact center is much like an old Amateur Radio that requires constant tuning to produce the best receiving and transmitting signals. These machines come with a panel full of dials and switches used to make sure the radio and the antenna are in perfect attunement. Similarly, contact center managers are constantly monitoring the call handle and queue times making sure the correct proportion of agents are staffed for email, voice, or chat processing. These managers require timely 15 or 30 minute latent reports to determine short term staffing levels. Most companies see the customer service departments as necessary expenses to keep their customers happy. Decision makers need nearly real-time information to make constant adjustments maximizing the efficiency of the staff and keeping their customers happy.

The challenge for BI professionals is, understanding the users’ needs well enough to deliver the correct solution for the need. There isn’t a one size fits all approach to BI delivery. The assembly manager needs metrics on how many completed plastic toys are failing inspection every half hour. Management needs to compare this month’s inspection failures to the samples before switching to the new vendor, perhaps a few times a week. The executive might want to know how sales are going this year compared to the last five, but she only needs this information on the first of the month when she first walks into the office. Each one of these examples has different requirements for the size of the data set, the amount of time the report needs to be displayed for, and the near or distant data term period access.

What’s the point? Go run a search on any technology job board for Business Intelligence or BI. Employers are looking for qualified BI professionals to deliver reporting solutions way that aide in the business decision making process. It’s a growing space/niche on par with security and mobile development. If you can get past the stigma placed on this practice by developers that “Reporting Work” is somehow inferior to software development, there is a lot of opportunity to be had.
