Getting started with Google BigQuery and GDELT Project
Once upon the time, the new kid on the block left more established search engines in the dust, then, after reinventing web-based email service, Google introduced its Apps. Today, let’s talk about one of the myriad services Google offers to us: BigQuery. Basically, this cloud-based service allows us to utilize Google’s hardware to store our own datasets or access public data on the go. Google provides API for Java, PHP, and Python access. In addition, various third-party tools now connect directly to BigQuery: Tableau, R, JasperSoft, and Simba to name a few. We get a 1 TB monthly usage quota to query BigQuery’s data for free. Some of the downsides of this service include: premiums for storing our own data and querying in excess of the free quota. We are also limited with data manipulation tasks we can perform in BigQuery; in fact, we can only append records to our table, we cannot update or delete them. Finally, this service uses a SQL language dialect, which lacks some of the SQL commands we are accustomed to: DISTINCT comes to mind, or resort us to some convoluted workarounds (try using the TOP command.) Meet, the GDELT Project – “the largest, most comprehensive, and highest resolution open database of human society ever created.” In this tutorial, we will learn some interesting facts about different countries, using GDELT data in BigQuery.

Excel Formulas vs. Functions – Auto Loan Calculator (PMT)
If you are like me, you are using terms Excel Formulas and Functions interchangeably. However, these expressions represent distinctly different concepts. We can think of a formula as a statement that returns results of a certain user-defined calculation. Formulas can contain values (numeric, date, text,) cell references, ranges of cells, named ranges; they can perform any mathematical operation (addition, subtraction, multiplication, division, exponentiation,) as well as evaluate results of Excel’s built-in functions…A function is a predetermined formula that helps us simplify complex procedures and operations. For example, great folks at Microsoft programmed different functions that allow us to sum a group of numbers, search for a specific word within a text string, determine current date and time, or even figure out amount of our loan payment. Ability to construct complex Excel formulas , using multiple Excel functions is one of the prerequisites for becoming an Excel expert. Formulas always start with the equal sign ( = ), and we always enclose functional arguments (if any) inside parentheses.
Let’s suppose that you need to calculate auto loan payment for your dream car – 2015 Ford Mustang GT. According to TrueCarPrice , for the base V8 model, you should expect to shell out $ 32,864 of your hard-earned dollars for this car; if you reside in the state that Ford Motor Company calls home. This price is comprised of $ 29,612 true value estimate, $ 567 market premium, $ 825 delivery charge, and state sales tax. According, to Bank Rate, you can realistically finance this purchase with a 3% interest rate loan. Since you just received your Holiday bonus, you want to put it towards a $5,000 down payment on your new car. Let’s calculate your monthly car payment using both: formula method without utilizing Excel functions: =P*i*(1+i)^n/((1+i)^n-1) , as well as through a formula incorporating Excel’s PMT function. Both of these methods rely on formulas to perform the necessary calculations, but only the second method makes use of an Excel function.
