Which database is best? The question, obviously, depends on what you want to use it for.
I, like most analysts, want to use a database to warehouse, process, and manipulate data—and there’s no shortage of thoughtful commentary outlining the types of databases I should prefer. But these evaluations, which typically discuss databases in terms of …Continue

As the amount of the data grows exponentially and terms such as big data become mainstream, the need to handle all this data has increased. Database skills have become some of the most sought-after in the job market today. SQL, which stands for Structured Query Language and is used for relational databases (RDBMS), is one of those skills. In fact,…Continue

In this blog, I will be discussing some distinct types of data involved in feedback. The types that I will be covering are as follows: 1) structural; 2) event; 3) quantitative; 4) contextual; and 5) systemic. In 2014, I recall reading a number of blogs about three types of data: prescriptive, descriptive, and predictive. There was a data scientist apparently on tour lecturing extensively about these three types. I don't recall the individual's name. Well, prescription, description, and…Continue

I rarely get to use a walkie-talkie during a course in school. As the snapshot of my desktop shows on the image below, I had both a multi-line telephone and portable radio. Just before the exam, I participated in a simulation. Our tabletop exercise contained an emergency scenario: a train derailment involving the evacuation of residents. I served as the Social Services Director. Although I didn't choose this role for myself, I thought it made sense given my graduate degree in the area of…Continue

The Unix Philosophy, summarized by Doug McIlroy in 1994:
Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface.
This is considered by some to be the greatest revelation in the history of computer science, and there’s no debate that this philosophy has been instrumental in the success of Unix and its derivatives. Beyond Unix, it’s easy to see how this philosophy has…Continue

What is a temporal database?
A temporal database is a database with built-in support for handling data involving time.
This definition is from Wikipedia. It is simple and straightforward. Since we expect every database to have some kind of support for time operations, we could say that all databases are temporal databases based on this definition.

Here’s a brilliant presentation from Mike Bowers, Principal Engineer at the Church of Jesus Christ of Latter Day Saints. It accomplishes two major objectives; Mike reviews the strengths and weaknesses of the five major classes of databases today (relational, dimensional, object, graph and document). He then dissects the major NoSQL databases on the market including MarkLogic, Mongo, Riak, Cloudant/Couch DB and Cassandra. How do they stack up? Are they enterprise ready? If developer…Continue
